Astrophotographer Josh Dury shares the camera kit he can’t live without

[ad_1]

He might have been shooting the stars since he was seven years old, but Josh Dury is adamant that astrophotography is for everyone – you really don’t need to be an astronomer.

In fact, the advances made in camera technology over the past decade mean that capturing high-resolution images with low noise – the holy grail for astrophotographers – has never been so straightforward.

All you need, says Dury, is a camera that can handle digital noise well, a wide-angle lens that will let in plenty of light via a large aperture and a solid platform to shoot from.

So read on to explore the essentials that this astro pro takes on every voyage…

Astronomical light rail costs, teacher shortage, Joe Biden, Vivek Ramaswamy, photography

Opinion editor’s note: Star Tribune Opinion publishes letters from readers online and in print each day. To contribute, click here.

•••

The front-page article in the Aug. 22 edition “Deal struck to cover light-rail shortfall” stirred boyhood memories of watching President John F. Kennedy address Congress in May 1961 to propose landing a man on the moon and safely returning him to Earth before the decade was out. Slightly more than eight years later, I watched Apollo 11 Commander Neil Armstrong step onto the moon’s surface in July 1969.

The Metropolitan Council’s version of Project Apollo, the Southwest light-rail line, seeks to transport persons safely between downtown Minneapolis and Eden Prairie, a distance of 14.5 miles. That is a much less daunting prospect than the average distance between the Earth and the moon of approximately 239,000 miles.

The line is now supposed to begin service in 2027, some 17 years after the Met Council assumed control of the project and twice as long as it took America to land a man on the moon. The Apollo 11 mission cost $355 million, which equates to an inflation-adjusted $2.95 billion. The latest cost estimate for the Southwest light rail project (a number which seems to be in a constant state of flux) is $2.7 billion.

Am I the only person who finds all of this remarkable?

Thomas Moore, Eden Prairie

•••

With an extension of the Blue Line light rail in early planning stages, now is the time to do what should have been done with the Green Line — elevate the tracks for the majority of the route. An “L” would have several advantages — the most important would be improved safety for pedestrians, bikes and cars. Also, shops along the route would benefit from street parking at near-current levels, and pedestrians able to get to the store without multi-block detours to the nearest sanctioned crossing. Light-rail drivers would be freed from having to stop for traffic lights or slow down for errant drivers and walkers, so the trains would be able to put on more speed between stops. If the “L” turns out to be the fastest way to get from A to B more people will ride it. Isn’t that sort of the point?

Rich Brown, Minneapolis

TEACHER SHORTAGE

I wish Mike Thompson had talked with a teacher before creating his political cartoon in Wednesday’s paper. He missed the point completely of why many teachers are leaving the profession. Certainly teachers are concerned about their students’ mental health and would like more support for disruptive students. But students are the reason teachers remain, not why they leave. Teachers have worked hard to gain knowledge in their subject matter and in methodology to teach all types of learners. The disrespect from politicians and others who think they are qualified to micromanage curriculum make the job nearly impossible. To top it off, teacher pay remains low while the bureaucracy expands and expands. Talk with teachers, please. They need community support.

Ruth Thorstad, Dresser, Wis.

JOE BIDEN

Regarding Ryan Winkler’s commentary “Skeptics like Phillips should count on Biden” (Opinion Exchange, Aug. 11), President Joe Biden certainly has had many accomplishments. But for some to dismiss or ignore the voices of others within the party at this point calling for alternate ideas, views, etc., is reckless.

Debate and competition during a primary season should be welcomed. Fresh voices and perspectives help us evolve and grow as a party. As Rep. Dean Phillips so clearly stated, it should be a competition, not a coronation.

But once the convention is held and the nomination completed next summer, we must turn out and support whoever the candidate is. Democrats should have learned in 2016 that unifying behind their candidate after nomination is crucial to victory.

Jeff Isaacson, Lino Lakes

•••

In the commentary “The 2024 primaries and your call to duty” the writer argues that Republicans “need to do the right thing” and vote what’s best for the country. That means not supporting the candidacy of Donald Trump.

I agree.

What’s confusing, however, is the writer goes on to say that Biden is too old to run again. That he plans to vote for a yet unnamed younger Democratic primary candidate without identifying their credentials.

Despite his age, Biden has had an extraordinarily successful first term with regard to the economy, civil rights and the environment. He is a kind and decent human being. Yes, he misspeaks. Stuttering has been a lifelong issue for him.

So far his Democratic primary opponents — authors Marianne Williamson and Robert F. Kennedy Jr. — have never won elected office anywhere. Who does this author intend to vote for exactly who is capable of beating either Donald Trump or Ron DeSantis in 2024? Running for president is extremely expensive. It would be extremely difficult for another Democrat to jump in at this point and run a national presidential campaign.

If Biden chose not to run, his logical successor would be Vice President Kamala Harris, whose national approval rating sits at 32%, according to a recent NBC News poll, and who polls well behind both Trump and DeSantis.

So the alternatives to Biden are an unpopular vice president and two authors whose far-left positions have limited national appeal. The hard reality is Biden is the strongest candidate for the Democratic Party in 2024.

I suggest the writer do the right thing and support him.

Jim Piga, Mendota Heights

VIVEK RAMASWAMY

The youthful voters whom Vivek Ramaswamy, the self-proclaimed leader of a “new generation,” attempted to reach out to at the Republican presidential candidate debate the other night probably are not aware that voting for him might be the last opportunity they get to cast a ballot for a while.

The 38-year-old wealthy entrepreneur, the youngest candidate, has proposed raising the voting age to 25 unless an individual volunteers for military service or passes some sort of civics test that he has described as the same as one given for naturalization for citizenship; in other words, treating them as mercenaries or immigrants.

Ramaswamy’s proposition is not an outlier. A few months ago, a Republican operative unveiled to party leaders and donors a multipronged strategy to curtail access to voting by younger people, particularly college students.

That approach, fleshed out by Ramaswamy, is part and parcel of the GOP’s voter suppression campaign, which has so far primarily been directed to Black people, other ethnic minorities and poorer people.

Now, Ramaswamy is making that concept a cornerstone of his party.

So, if younger voters are attracted to his fresh face and anti-politician rhetoric, they ought to be aware that voting for him may lead to their disenfranchisement.

PHOTOGRAPHY

A newspaper does many things but on Wednesday the Star Tribune did the impossible with its front-page picture: It made me 17 again, if only for a few minutes.

The picture of two young teenagers sitting on a downed tree limb over a cool stream has stayed with me more than any other newspaper image in a long time.

The portrayal of a respite of cool water on a scorching day was also a symbol of our need for a respite — if only for a moment — from the steady drumbeat of war, politics and crime, which dominate the daily paper.

A news organization’s job is to provide a snapshot of a day in the life of our collective existence: good, bad and ugly.

On Wednesday, the Star Tribune, thanks to photographer Renée Jones Schneider, did that magnificently.

TV Star Rubina Dilaik On Himachal’s Disaster

[ad_1]

‘Family, friends, far off relatives, almost everyone has been impacted by nature’s fury.’

IMAGE: A row of buildings in Kullu district collapsed on August 24 and hundreds of travellers were stranded in relief camps after landslides blocked the road to Mandi in rain-battered Himachal Pradesh. Photograph: ANI Photo

Rubina Dilaik is a popular face on television thanks to dramas like Chotti Bahu, Shakti — Astitva Ke Ehsaas Ki and Punar Vivah — Ek Nayi Umeed, along with reality shows like Fear Factor: Khatron Ke Khiladi 12, Jhalak Dikhhla Jaa 10 and Bigg Boss 14 which she won.

The actress who made it to the British weekly Eastern Eye‘s 2022 list of ‘Top 50 Asian Stars’, ranking 31st, was born in Shimla, went to school and college there, and won two local beauty pageants, crowned Miss Shimla in 2006.

Understandably then, Rubina is disturbed by the natural disasters plaguing her home state since the onset of the monsoon this year.

Speaking to Rediff.com Senior Contributor Roshmila Bhattacharya from Los Angeles, Rubina says, “Each one of us is contributing to these natural calamities. We ourselves are responsible for incurring nature’s wrath.”

 

‘Family, friends, far off relatives, almost everyone has been impacted’

The news reports coming in from Shimla and other parts of Himachal Pradesh of devastating landslides leading to roads and even houses cracking are terrifying and heart-wrenching.

Family, friends, far off relatives, almost everyone has been impacted by nature’s fury.

There’s been loss of crops, but by the grace of God, I’ve not heard of any loss of human life or even houses within our circle.

Of course, property has been damaged, fields too, and business have been majorly impacted.

But I believe that if a person is safe in the midst of all the death and destruction, then that’s a blessing to be counted.

I am currently in Los Angeles on a leisure trip. Once I am back, I will definitely visit my parents in Shimla. They were in Mumbai with me before I left for LA.

‘Our doors are open to anyone needing help’

In a personal capacity my family is extending help to neighbours and those in the surrounding village to the best of their capacity while the government debates on compensation which is a process in itself.

As public figures, both Abhinav (actor-husband Abhinav Shukla) and I have always reached out.

Our doors are open to anyone needing help.

We have also gone through a pandemic worldwide and it has taught us how to face a disaster situation.

Life itself teaches you how to deal with a crisis.

I’m deeply rooted to my birth place and culture.

The last time I visited Himachal Pradesh was in the first week of July.

Shimla is my home town and there are a lot of memories.

Even the Summer Hill, where a house went down the hill recently, brings back a wave of nostalgia because while in school, we were taken there for picnics.

I haven’t visited the Shiv temple which was also completely destroyed in a landslide, burying some devotees.

The news broke my heart.

The videos coming out of Mandi which has also been ravaged by flash floods and landslides are equally heart-wrenching.

My prayers and sympathies are with all those going through difficult times.

IMAGE: A bridge near the flooded Chaba power house in Shimla. Photograph: ANI Photo

‘It’s important to have a balanced view about both the economy and ecology’

Abhinav is a keen mountaineer and has successfully climbed the highest mountain peak in Ladakh, Stok Kangri, with his brother in 2017.

Whenever he has come back from climbs, he has spoken about how governments in every state are taking good care of these mountains.

They do not give permission for any climbs if they feel the mountain will not support them.

Mountaineers, like my husband, too are very responsible, environmentally conscious and planet friendly.

There have rarely been reports of irresponsible climbs.

We are living in tricky times and it’s important to have a balanced view about both the economy and ecology.

A state like Himachal Pradesh needs tourism to flourish, but at the same time it should ensure that tourism does not have an adverse impact.

Yes, what is happening there right now will create some fear, both among locals and tourists.

In a way fear is good because you realise nature’s wrath and based on this knowledge, can make wise decisions to build a better tomorrow.

But living in fear and not wanting any kind of development can also be counter-productive.

‘Each one of us is contributing to these natural calamities’

Experts have been blaming the present crisis on unplanned development and increased tourism, particularly in Shimla. I agree, partially.

If we had been more systematic in developing our infrastructure, maybe this might not have happened.

But that is an idealistic thought.

The town of Shimla was built by the British before Independence, so it’s too late to ponder on this.

What we can discuss is global warning which is affecting almost every part of the world.

It’s just unfortunate that it has affected my state more severely.

Each one of us is contributing to these natural calamities.

We ourselves are responsible for incurring nature’s wrath.

Our ego makes us believe that we are in control, but it’s high time we let go of our ego and realise that nature knows how to take care of itself.

Nothing, and no one, is above nature.

And till we realise this, we will continue to incur nature’s wrath.

Watch: Massive landslide in Himachal’s Kullu, several houses collapse

See Saturn at its biggest and brightest of 2023 this weekend

[ad_1]

Saturn makes for an excellent skywatching target this weekend, thanks to its current position in the solar system.

The ringed gas giant will reach opposition, meaning it will be situated directly opposite from the sun with Earth in the middle. Around the same time, Saturn will reach perigee, its closest approach to Earth, according to In-The-Sky. The combination of these two celestial events means Saturn will appear at its biggest and brightest this weekend. The planet should remain visible through February 2024.

Top Innovative Assignment Formats That Foster Active Learning In Students

[ad_1]

In the rapidly evolving academic setting of the 21st century, the demand for innovative assignment formats is stronger than ever. Students are ever more engaged by dynamic, interactive learning methods that transcend the conventional and usher in the novel. As a result, educators must explore new and engaging assignment formats that foster active participation and stimulate curiosity and intellectual growth in students.

Top Innovative Assignment Formats

The Concept of Active Learning

Active learning is an instructive method that engages students in the learning process directly, often via problem-solving assignments, group discussions, or practical projects. The aim is to stimulate a higher level of thinking, leading to improved understanding and retention of information. This multifaceted approach allows students to apply knowledge, promote collaboration, boost confidence, and nurture critical thinking skills.

In the context of innovative assignments, active learning ensures assignments are more than mere completion tasks. Instead, they become engaging activities that stimulate critical thinking, independent research, collaboration, and problem-solving—laying foundations for lifelong learning.

Traditional Assignment Formats and Their Limitations

Traditional assignment formats range from tests, quizzes, and essay assignments to exams. While they play a crucial part in the learning process, they have been found to limit the full spectrum of learning, inhibiting creativity, critical thinking, and collaborative capabilities. Hence, the need for innovative assignment formats has become a central focus in modern educational philosophy.

Innovative Assignment Formats and How They Foster Active Learning

Several alternative assignment formats have emerged in the past decades that have proven effective in triggering student engagement and inspiring active learning. The following are some note-worthy examples:

Problem-Based Learning Assignments

Problem-based learning assignments present complex, real-world problems that students work to solve, leveraging their analytical skills and collaborative effort. This method places students in the active role of problem-solvers, promoting deep understanding and knowledge application in various contexts.

Flipped Classroom Assignments

The flipped classroom approach takes the traditional teaching model and turns it on its head. Students are tasked with learning new concepts independently, using technological resources like online lectures and educational videos. Later, classroom time is utilized for discussions, problem-solving, and teacher-guided activities to cement their understanding.

Top Innovative Assignment Formats

Collaborative or Group Assignments

Group assignments encourage cooperation among students, intensifying their practical understanding of the topic at hand. They help to improve students’ communication, teamwork, and leadership skills, fostering their ability to interact and function in a group setting.

Digital and Technology-Based Assignments

Education is continually evolving to keep up with the digital revolution we’re experiencing globally. Digital and technology-based assignments are now becoming an integral part of modern learning. These assignments leverage the power of technology, encouraging students to interact with various digital platforms to enhance their learning experience. They can involve activities such as participating in online forums, creating multimedia projects, or using educational apps specifically designed to boost comprehension and engagement in various subjects.

As Johannes Helmold, an expert at Academichelp, notes, these innovative assignments not only make learning more exciting and relevant but also equip students with indispensable digital skills for the future. Another significant advantage of such assignments is that they allow for a more personalized learning experience. For example, assignments posted at Academichelp’s site can be customized to each student’s unique learning pace and style, maximizing their potential for academic success.

Moreover, several educational platforms like Tutorbin.com are making it easier for teachers to incorporate digital and technology-based assignments in their curriculum. These platforms provide a wide range of resources and tools to facilitate interactive and engaging digital assignments, thus fostering a more immersive and dynamic learning environment.

Top Innovative Assignment Formats

Real-World Scenario Assignments

Real-world scenario assignments invite students to apply their knowledge and skills in practical scenarios, simulating real-life situations. This format can stimulate critical thinking, creativity, and innovation, helping students realize the relevance of their learning to their future career and life.

Practical Tips for Educators to Implement Innovative Assignment Formats

For educators to integrate innovative assignments successfully, they must adapt to the students’ needs, capabilities, and interests. Appropriation of technologies and resources is key, and providing a conducive active learning environment is paramount. Regular feedback and guidance motivate students and help them align their learning efforts effectively.

Case Studies and Examples of Successful Innovative Assignment Formats

Many case studies demonstrate the power of innovative assignments in fostering active learning. For instance, in schools employing the Flipped Classroom Model, researchers have found significant improvements in student comprehension and engagement. Similarly, the use of digital assignments has been linked to improved technical skills and increased student motivation.

Top Innovative Assignment Formats

Conclusion

Embracing innovative assignment formats is invaluable in fostering active learning among students. The inclusion of problem-based learning, flipped instruction, group assignments, digital projects, and real-world scenario tasks into curriculum design helps to create a more engaging, interactive, and enriching learning experience. As we celebrate the diversity and individuality of our classrooms, let us also diversify our teaching methods for the benefit of our future generations.

De nuevo en mi rincón del Maestrazgo

[ad_1]

Acabamos de finalizar la segunda parte de nuestras astrovacaciones. En el novilunio de julio estuvimos en Paravientos (Cuenca) y para el novilunio de agosto hemos regresado un año más a nuestro rincón del Maestrazgo (Teruel). Si no me equivoco es el 4 año que venimos aquí por vacaciones y esto obedece a varias causas: la excepcional calidad del cielo, los impresionantes paisajes, la tranquilidad, el atractivo del turismo paleontológico y la gastronomía. No os voy a mentir, en pocos lugares encuentro un cielo y unas condiciones de observación como aquí.

Afortunadamente este año la meteorología ha sido benévola y hemos podido aprovechar casi todas las noches. Además las temperaturas han sido agradables durante toda la semana y es que este agosto ha sido abrasador, llegamos cuando finalizaba una ola de calor y nos fuimos cuando comenzaba otra por lo que nos sentimos afortunados de haber podido disfrutar de noches transparentes libres de calima.

De Andrómeda a las Pléyades, uno de los grandes campos que pude disfrutar durante estas vacaciones.

Noches bien aprovechadas

Como ya sabrás si eres un lector habitual de este blog estuvimos alojados en Masada Andabe, una masía a las afueras del pueblo de Cuevas de Cañart. Su ubicación, alejada de cualquier punto de contaminación lumínica la otorga un cielo de gran oscuridad. No es un lugar apto para cualquiera. Olvídate de usar el móvil, no hay cobertura, no hay Internet. El agua potable tienes que traerla en garrafas desde el pueblo a unos 7 Km por una «carretera» que pondrá a juego los amortiguadores de tu coche y los empastes de tus muelas. No es un sitio para personas dependientes de Internet o TV por cable. Aquí vienes a desconectar y a disfrutar de unos cielos oscuros (cada año menos, por desgracia).

La Masada es perfecta para la práctica de la astronomía. Es nuestro rincón del Maestrazgo.
La masada es perfecta para la astronomía. Cielos oscuros y comodidad para plantar el telescopio en la propia casa rural.

Llegamos el viernes 12 y a pesar de las 4 horas de viaje no pude resistirme a montar el telescopio en cuanto se puso el Sol. Estuve aprovechando para calcular la visibilidad solar para ese día ya que en 2026 hay un eclipse total y la franja de totalidad pasa por Teruel. Lamentablemente no hay visión directa del Sol desde la casa a la hora del eclipse. Tendremos que buscar un lugar más elevado si queremos verlo. No os durmáis, hay que ir buscando sitio porque se va a poner todo hasta arriba, el eclipse será al atardecer y necesitarás estar en un sitio elevado. Tengo otras dos oportunidades para probar sitios los próximos años antes de decidirme.

La primera noche fue muy aprovechable aunque con algo de calima, ya en retirada, después de unos días abrasadores. Estuve sacando la luminancia de un objeto en el Cisne y pude aprovechar hasta la salida de la Luna, un poco antes de las 04:00. Se dejaron ver algunas Perseidas. Saturno y Júpiter estuvieron presentes durante casi toda la noche, el último brillando con gran intensidad sobre el cielo turolense. Curiosamente, al otro lado del mundo, el japonés Hideo Nishimura estaba descubriendo un nuevo cometa en la constelación de Géminis. Unos días después tendríamos ocasión de fotografiarlo, ya llegaremos a ello.

Por fin pude quitarme la espinita de fotografiar Rho Ophiuchi

Fuertes tormentas y otras lluvias de estrellas

Al día siguiente, sábado, aprovechamos para ir al pueblo a hacer compra y por la noche tocaba observar las Perseidas pero las nubes hicieron acto de presencia y tuvimos un buen tormentón por la tarde que dejó mucha humedad ambiental. Al anochecer el cielo estaba cubierto y la humedad altísima, aún así monté el telescopio y nos pusimos a esperar. Hasta la 01.00 de la mañana no se despejó por completo y fue entonces cuando pudimos empezar a ver las primeras Perseidas de la noche, aunque no tenían una actividad muy elevada.

A eso de las 02:30 el SQM marcaba 21.54 con una temperatura IR en el cenit de -5º (ambiente de 19º y HR del 99%) pero ya sin restos de la calima de los últimos días. La humedad estaba disparada y en el telescopio tuve que encender las cintas calefactables. Entre las 01:30 y las 02:00 vimos unos 21 meteoros y en la siguiente media hora 12 meteoros. A partir de las 03:00 la actividad aumentó bastante incluidos algunos meteoros muy brillantes que dejaban estela a su paso y un par de bólidos muy luminosos.

Estuve sacando el color de la nebulosa del día anterior y cuando llegó el amanecer astronómico me dispuse a hacer los flats pero la lámina empezó a hacer cosas muy raras, parpadeos y cambios de brillo. Era la primera vez que me pasaba y todavía no se a qué se debió el problema, tal vez fuera la alta humedad o un voltaje bajo de la batería… el caso es que los flats no salieron bien y opté por no desmontar la cámara cuando recogí el equipo.

Lo bueno de observar desde la propia casa es que tardo muy poco en recoger y puedo dejar el tubo totalmente montado y sin guardar en la caja. De esta forma podría volver a intentar hacer flats al día siguiente y valdrían para la sesión anterior. Recordad, si no tocáis nada en el tren óptico los flats de un día podrían valer para otro en el peor de los casos (rezad para que no se deposite ninguna mota de polvo en el tren óptico).

Un gran campo dentro del Cisne con anotaciones de constelaciones y objetos.

Segundo pico de Perseidas

La siguiente noche, del 13 al 14 de agosto hubo una gran actividad de Perseidas desde primera hora de la noche. A eso de las 00:30 el SQM daba 21.34 y el IR en cénit -13º con temperatura ambiental de 20,4º y HR del 82%. La noche estaba despejada aunque soplaba una brisa intensa en ocasiones. Comencé a sacar el color del siguiente objeto, una nebulosa en Cefeo y estuve observando con los prismáticos durante buena parte de la noche. Me perdí en las nebulosas de Sagitario y comprobé una vez más que la Nebulosa de los Velos es visible con unos 10×50 si tienes la suficiente paciencia y un buen cielo. Me sorprendió observar la Nebulosa de la Hélice, especialmente me sorprendió su gran tamaño comparado con otras planetarias como M27, por ejemplo.

También estuve sacando algunas fotos con la Canon y la StarAdventurer. Un gran campo de la vía láctea y luego me estuve centrando en diferentes constelaciones. Perseo, Casiopea, Hércules, Capricornio… en todas las fotos aparecía un fondo verdoso, sin duda la presencia de airglow era patente y eso explicaba las variaciones del SQM durante la noche.

Al final de la sesión pude hacer correctamente los flats. Los problemas del día anterior habían desaparecido. No tengo ni idea de qué falló en la sesión anterior, espero que sea algo puntual.

La noche del 14 al 15 el SQM marcaba 21.53 un poco antes de las 00:00 de la noche con IR de -10º (temperatura ambiental de 21º y 65% de HR) con una brisa un poco más fuerte que el día anterior. Había alguna tormenta al norte, a la altura de Huesca y se veían los relámpagos en la distancia.

Persistía una moderada actividad de meteoros y con el telescopio me puse a captar la luminancia de la nebulosa de Cefeo que comencé a sacar el color el día anterior. Fue una noche muy buena en la que el SQM llegó a marcar 21.65 a última hora.

La noche del 15 al 16 tuve que empezar algo más tarde porque había algunas nubes en el cielo. Eran nubes altas y dispersas, llegó un momento en que el cielo se despejó pero a eso de las 02:00 se cubrió totalmente y desistí. Era la 5ª noche de astronomía consecutiva y el cansancio se acumulaba así que en el fondo hasta agradecí el poder dormir un poco más esa noche.

También algo de turismo paleontológico en este rincón del Maestrazgo

Al día siguiente hicimos una ruta turística y nos pilló una granizada en el camino. Las tormentas por esta zona del Maestrazgo son habituales en esta época del año y en ocasiones basntante intensas, con granizo de buen tamaño. En esta ocasión no pasaron del diámetro de una canica y rezas por que tu coche no sufra daños. De vuelta al llegar a la casa rural nos pilló un reventón tremendo de agua, hasta tuve que parar el coche en el pueblo porque no había manera de conducir. Las calles del pueblo bajaban como ríos . Duró unos pocos minutos pero descargó una buena cantidad de litros.

Al llegar a la casa rural nos dimos cuenta de que me había dejado las sillas y la mesita plegable fuera y estaban totalmente caladas de agua. Voy a tener que buscarles reemplazo porque están ya algo viejas y este «lavado» era lo que menos necesitaban.

Por la noche la temperatura bajó bastante y estuvimos a unos 17,7ºC con una HR del 99%. De hecho me tuve que poner pantalón térmico y el de sky porque con el vaquero era desagradable estar. El SQM marcaba 21.38 y el IR -10º, pero las condiciones fueron mejorando gracias a una brisa seca y cálida.

Fue otra noche totalmente aprovechable porque a medida que pasaba el tiempo y con la brisa seca iba disminuyendo la humedad y las condiciones mejoraban a cada hora con un SQM máximo de 21.52. Pude sacar más tiempo de luminancia con el telescopio y pasé un buen rato gozando con los prismáticos. Sobre todo disfruté mucho de la Galaxia de Andrómeda, que creo que es la vez que mejor la he visto con prismáticos cuando estaba próxima al cénit. La imagen era muy contrastada y se apreciaba con todo lujo de detalles con sus galaxias satélites M32 y M110.

Ruta del silencio.
Mirador de la ruta del silencio. Una foto que tenía en mente desde hacía años.

Al día siguiente hicimos otra ruta turística hasta Galve para ver el nuevo Museo Paleontológico. A la vuelta paramos a cenar en Ejulve y después fuimos hasta un mirador cercano para hacer una panorámica nocturna que tenía en mente desde hace años. Al llegar al mirador saqué el trípode y la StarAdventurer y dejé la mochila de la cámara en el suelo pero a pocos centímetros ví algo que me llamó la atención. Apunté bien con la linterna (era ya de noche) y vi un escorpión muy quieto. Al principio pensé que estaba muerto pero al dar una patada en el suelo cerca de él levantó el aguijón y comenzó a correr. Rápidamente quité la mochila del suelo y continué iluminándole con la linterna mientras se alejaba. Decidí dejar la mochila en el coche y le dije a Diana que estuviéramos atentos por si veíamos alguno más en las proximidades. Al final sacamos unas cuantas fotos y decidimos bajar por la carretera un poco más para sacar otra panorámica de otro lugar especial, los órganos de Montoro.

montoroorganosweb

La carretera era sinuosa y estrecha así que había que ir despacio. Ya habíamos visto un corzo y un zorro cruzarse en el camino así que yo iba despacito y muy atento. De hecho vimos un corzo atropellado unos kilómetros más adelante. Al final llegamos a nuestro destino. Volví a montar la Star Adventurer y sacamos las fotos que queríamos. La temperatura era alta y yo estaba con pantalones cortos, no hace falta que os diga que los mosquitos se cebaron conmigo.

A la vuelta, cuando cogimos el camino de la casa rural también iba muy despacio por si se cruzaba algún animal y justo en un momento veo algo salir por mi izquierda y pisé el freno a fondo. El coche se paró y se caló y vi un animal salir prácticamente de delante del coche hacia el lado derecho e internarse en el bosque corriendo. Al principio pensé en un mapache pero después lo identifiqué mejor como un tejón. Nos llevamos un buen susto y si no le dimos fue precisamente porque iba a menos de 30Km/h. Por la noche hay que ir con mucho cuidado por estas carreteras. Mas adelante también vimos una pareja de chotacabras posados en el asfalto que remontaron el vuelo al acercarnos.

Esa noche no monté el telescopio a pesar de que estaba muy despejado, pero ya era algo tarde y estaba cansado del viaje.

A la noche siguiente si que monté el telescopio y a eso de las 2 de la mañana con 22º y una HR del 40% se notaba la entrada de una masa de aire cálido y me quedé aprovechando hasta casi las 6 de la mañana completando algunas horas más de luminancia. Fue una noche totalmente aprovechable en la que gocé de nuevo con los prismáticos 10×50 y los 2,1×42.

También aproveché para fotografiar el cometa 12P/Pons-Brooks que tuvo un estallido de actividad hace unas semanas y el cometa c/2023 P1 a última hora de la noche. Estuve intentando observarlo con prismáticos pero todavía no está lo suficientemente cerca ni es lo suficientemente brillante para ello. En cualquier caso poder fotografiarlo fue un broche de oro perfecto para unas vacaciones estupendas. El año que viene exploraremos nuevos sitios pero sin duda volveremos aquí en más ocasiones. Es un sitio que merece la pena si te gusta la astronomía.

India | Photography and the return of analogue

[ad_1]

In 2015, when I quit my job as the editor of a fashion magazine to study photography in Paris, I was a senior student. Very senior. Imagine my surprise then when my international classmates — aged mostly between 18 and 28 — were all shooting film, something I’d given up in 2006.

Like most photographers pre-digital era, however, I had shot slide, colour negative, and black and white film. I had push processed, cross processed, and even taken a course in film processing and printing. I thought I was stone age, except, as it turned out, that’s where the world now wanted to be.

As I was swept up in its wake — unearthing an old medium format twin lens reflex Yashica gifted by an uncle, its leather cover falling apart, and purchasing boxes of 120 Kodak Portra — I could see film photography take off.

There were many signs. First, the 25.5 million posts on Instagram under the hashtag #filmisnotdead. Then, the reissue of out-of-production film and film cameras such as Kodak Ektachrome and the Leica M6, respectively. There were also the soaring sales of Fuji Instax for instant photography and the 2017 return of Polaroid as Polaroid Originals, after its 2001 bankruptcy. And then, in 2022, Ricoh Pentax announced it was developing a new 35mm film camera.

In India, in 2016, by popular demand, Radhakrishnan Vijayakumar, Group CEO of Srishti Digilife, had started to import and sell film from Kodak, Ilford and Lomography, and develop chemicals for the film in the Indian market. Since then, Ilford’s revenues have grown from ₹50 lakh to ₹4.5 crore, while Kodak has shot up from ₹85 lakh to ₹4.8 crore last year.

Join the community

India has seen a boom, too. In the past three years, several WhatsApp and Facebook groups for enthusiasts and professionals have sprung up — to share resources, exchange ideas, and troubleshoot problems. Film photography workshops have become the order of the day as have film processing studios, such as Zhenwei in Mumbai (founded in 2020, it processes around 300 rolls of film every month).

Community dark rooms have also mushroomed across the country, from Siliguri to Goa, Delhi, Gurugram, Chennai, Bengaluru, and Puducherry. Many of these spaces, such as the Chennai Photo Biennale (CPB) and Zhenwei, sell their own respooled film (bought in bulk, cut, and spooled onto new canisters for very economical rates, given that film prices have increased dramatically year-on-year).

Artist and photographer Sasikanth Somu, 56, runs a community darkroom at the Centre d’Art in Auroville. Started during the pandemic, at the tail end of 2020, he holds workshops as well. One of the reasons film is back, he feels, lies in it being the antithesis of today’s instant culture — where you can shoot, upload and receive appreciation in less than a minute. “My students get hooked to that process of not seeing the image straight away, of waiting to process their film rolls, print photographs, and only then see the positive images.”

Menty Jamir, a photo-artist and creative director based between Delhi and Shillong, started shooting film three years ago when friend and Magnum photographer Sohrab Hura gave her his medium format camera with 20 black-and-white rolls, as she was heading home to Shillong during the pandemic. In 2021, out of curiosity, she signed up for the Photo.South.Asia darkroom workshops, initiated and mentored by Delhi-based photographer Srinivas Kuruganti — to learn more about the analogue approach, print-making, and gain the confidence to shoot film. “The change in form itself can enhance one’s way of seeing and open a fresh perspective,” she says.

In short, like any self-respecting hero, film photography has risen victorious from the dead. Except that there’s a twist to the tale. It turns out the hero is not film photography as much as analogue photography. What’s the difference? The latter encompasses all the processes that were used to capture and create images from the 19th century onwards, well before the invention of the 35mm camera. Some of them, such as cyanotypes (a contact printing process that produces cyan blue prints), don’t even use a camera.

Alternative processes, or historic processes, as they are called, are having their moment in the sun. Popular filters on social media say something about the likeability of the medium. And as if to prove the point, the ongoing fourth anniversary celebrations of Museo Camera in Gurugram include exhibitions of historic cyanotype, gum bichromate, and albumen prints.

For the love of the dark

For Varun Gupta, 41, analogue artist, director and co-founder of Chennai Photo Biennale — which has just moved into new premises that offers a community darkroom as well as workshops and kits for alternative processes — it is the element of chance that accounts for the appeal of alternative process. “With digital, everything has become so controlled that one finds it almost impossible to truly surrender. [With alternative process] you’re not really sure what you’re going to get; you modify and troubleshoot. It’s also very tactile.”

The pandemic was a tipping point for alternative processes, he says. Gupta saw a global spike in interest in 2020. That was also the year CPB started doing cyanotype workshops. At the end of the first wave, the sessions, which took place in parks, attracted participants to the tune of a few hundred at a time; Gupta attributes it to digital revulsion. “We wake up in the morning and stare at a phone, before you sleep you stare at it. It’s this circle of consumption on screens that has made us collectively yearn for something analogue.”

In the past three years, they have taught the process to more than 2,000 people. CPB now sells two types of cyanotype kits (starting from ₹1,200) and has an e-learning course, too. Gupta also teaches salt printing and Van Dyke brown and is looking forward to learning the gum processes.

Another practitioner is Sarang Sena, 37. In early 2018, the Delhi-based visual artist decided to use the wet plate collodion (a 19th century process) for a personal project. He spent the good part of a year fine-tuning the chemistry for Indian weather. Then came the pandemic and a broken enlarger, which gave him one last step to complete: create his own enlarger. Once he had done that, he realised he could make his own large format view camera — big wooden boxes with bellows on a stand that most of us had last seen in movies from the 1940s and 50s.

The culmination was a series titled Six Feet Apart, where he created portraits of people who visited his house. “With a view camera, there’s a lot more interaction with the subject or the space, and a big thought process before you even set up the camera,” he says. Another of his portrait series, Contributors — celebrating a diverse set of individuals for their contribution to a COVID-hit society — made around the same time appeared in Vogue Italia. A key factor that drew Sena to this process was that each image was one-off, “there’s no way to repeat that particular image”.

He has since set up a studio space called Class of Yesterday: CYStudios in Delhi, where anybody can book their own unique portrait. Footballer Sunil Chhetri is a client, as are actors Dipannita Sharma and Nasir Abdullah.

MAP does its bit

Outside of workshops and analogue communities, spaces such as The Museum of Art & Photography (MAP) in Bengaluru are also playing a role in this revival. “One of the largest collections at MAP is photography that spans from the 1850s to the present. And a big part of it is based on film and alternative processes like albumen and bromide prints, woodburytype, and silver gelatin prints,” says Prachi Gupta, a senior archivist at the museum. Two ongoing exhibitions — Time and Time Again, a retrospective of artist Jyoti Bhatt, and With Great Ease, an exhibition of late photographer T.S. Satyan’s work — are all film. “The exhibitions show original silver gelatin prints and contact sheets; the Satyan exhibit also has his Six-20 Brownie C camera on display. And the response from all age groups has been spectacular. We see people spending time with the photographs, inspecting them closely, reading the inscriptions,” says Gupta, adding, “Through exhibitions, workshops and our digitised collection, the aim is to constantly expose and educate the audience.” MAP recently conducted a workshop on cyanotype and more are in the pipeline.

Making the alternative accessible

There are a few photographers whose work I’ve been obsessed with for a long time: Sarah Moon, Paolo Roversi, Jack Davison, all of whom shoot fashion, though they are not just fashion photographers. Their images are the result of a combination of shooting and printing, the latter as important as the former. Moon uses direct carbon printing for her super saturated hues and is happy to degrade her negative; Roversi, who has possibly the largest stock of the now discontinued 8×10 Polaroid film, does platinum palladium prints; and Davison recently did a series of photogravure from his digital work.

As somebody who was wondering how to even attempt any of these methods, learning that they are, for the most part, accessible in India, feels liberating. Three touchstones have emerged to learn alternative processes in the country: Maze Collective Studio in Delhi, Studio Goppo in Santiniketan, and Studio Kanike in Bengaluru.

Maze Collective, co-founded by Ashish Sahoo, 34, and Zahra Yazdani in 2020, offers one-month alternative process residencies and shorter film photography workshops. Sahoo has also created one of India’s cheapest large format view cameras, essential to some alternative processes, with his collaborator Himanshu Bablani, who runs a makerspace called Banana House in Delhi. “You can get some really cheap cameras abroad, but by the time they come to India with customs duties and all, they become expensive. Plus, if any problem arises with the camera, we can troubleshoot and send you the parts,” he says, explaining that most parts are 3D printed and the rest are laser cut with stainless steel.

Santiniketan-based Arpan Mukherjee, 46, has been practising alternative processes the longest. He started in 2000-2001, not as a photographer but as an artist working with photosensitive materials in the form of silkscreen. “With alternate process, you can click an image, print it on your own, on leaves, on paper, on any surface,” he says. “And you have to print it with your hands. So the quality of the photography doesn’t depend on the camera, or the printer, but on your skill and craftsmanship.”

In 2015, the artist and associate professor in Santiniketan’s Department of Graphic Art, co-founded Studio Goppo with his partner Shreya to grow the alternative processes community. They offer two-week to two-month residencies to teach not only commonly known processes but also rarer ones such as calotype (where paper coated with silver chloride is exposed to light in a camera obscura) and colour gum bichromate (a process using salt of dichromate that produces painterly images).

Trying hybrid methods

Interestingly, alternative processes aren’t about shunning modern technology. All the practitioners work with contemporary technology when required, and in fact, use hybrid methods to create something new. “You can click an image on your digital camera, create and print a digital negative,” Mukherjee explains.

With such processes also come more layered ways of storytelling. Vivek Muthuramalingam, photographer, artist, and founder of Studio Kanike in Bengaluru, talks about elevating his documentary photography practice. For a series that he did on Goa’s poders (bakers) a few years ago, he used seawater from nearby beaches to create salt prints — and as he described in a personal essay in the Dark ‘N’ Light zine, the “organic substances that came along with the sea water, like plankton and algae, imparted its own tonality and hue to the print”.

Muthuramalingam explains the versatility of the process to me with another example: “For instance, if I were doing a work that follows the Silk Route, and I go to Cambay to find nothing there [in the Travels of Ibn Battuta, the scholar-traveller wrote an entire chapter on the city that was once an important trading centre in Gujarat], I could pick up salt and create the whole series.” The choices are endless: maybe cyanotype for a theme of loss steeped in blue or Van Dyke brown for sepia-tinted memories?

These processes are not just curiosities anymore; they have started to be woven into mainstream photography and art, textile design, and even magazines and online. And the trend isn’t showing any sign of slowing down.

Print perfect

 Some common alternative processes

Albumen prints: Popular from 1855 to 1895, as the name suggests, paper is coated with egg white — which makes it smooth and shiny — and then silver nitrate. Images are contact printed and change hue over time.

Cyanotypes: Considered the gateway to alternative process, it’s a non-silver, contact printing method that gives a blue print (the architects’ blueprint takes its name from it) is easy to use on a variety of media including cloth.

Gum prints: Gum oil uses a mix of Gum Arabic and oil paint and the final result is black and white and looks like something drawn with charcoal. Gum bichromate is a process where you use watercolour and it can be colour or black and white. It has beautiful tones and colours.

Platinum palladium: Considered the acme of alternative prints for its ability to reproduce a large scale of tonalities, its soft grays, and its archival qualities. The price of platinum makes it an expensive and rare proposition.

Salt prints: A process that combines salt, silver nitrate, and a UV light to produce reddish brown images. In use till the 1850s.

Van Dyke brown: Named after Flemish painter Anthony Van Dyck who was famous for a particular hue of brown, it is also a contact printing process.

Wet plate collodion: It’s a 19th century photographic process that uses a glass or metal plate coated with collodion, immersed in silver nitrate to make it light sensitive, and inserted into a large format camera where an exposure lasts between 4-30 seconds, while the solution is still wet. The plate is then rushed to a dark room and covered with developer liquid, at which point you get a negative. A fixing bath turns the image positive. It’s called an ambrotype if it’s on glass and a tintype or ferrotype if it’s on metal. The result is an ethereal image as collodion renders tones differently from those of black and white photography. Dry Plate Collodion is where the plates are coated with a gelatin emulsion which creates long lasting negatives that can be easily stored and developed.

We took some of the best flagship phones for an astrophotography face-off — here are the results

[ad_1]

All smartphones can take good looking photos when it’s sunny and bright out, but very few are equipped to tackle the night sky. Astrophotography has increasingly become more than just a novel hobby, moving closer to the mainstream where you no longer need the expertise and patience to see the stars in photos. 

One reason why? Many of the best camera phones around leverage their respective night modes to draw out the twinkling lights above us from the darkness of space.
