Siguiendo con la presentación de sus últimas cámaras de nueva generación QHY ha presentado el modelo QHY5III585C una cámara a color enfocada a astrofotografía planetaria y guiado con una sensibilidad al infrarrojo cercano similar a la QHY5III462C pero con mayor rango dinámico que ésta.
La QHY5III585C trae un generoso sensor de 1/1,2 pulgadas y un excelente desempeño con nulo amp-glow. Con esta cámara se incluye un filtro de corte UV/IR y un filtro IR850nm.
En estos nuevos sensores, la parte del fotodiodo del pozo de píxeles es físicamente más profunda que en los modelos anteriores. Esto permite que los fotones de longitudes de onda más largas penetren más profundamente en el sustrato lo que aumenta enormemente la sensibilidad del sensor a la luz roja e infrarroja cercana alcanzando sensibilidades similares a la de la luz visible.
Con esta cámara tendremos un alto rango dinámico (HDR) de 88 dB, aproximadamente ocho veces más que el sensor IMX485 de la generación anterior.
Con su pixel de 2.9um de tamaño esta cámara es perfecta para astrofotografía planetaria y con un sensor de 3856*2180 píxeles nos presenta la posibilidad de realizar grandes capturas en fotografía lunar de 8.4 Megapíxeles.
Al igual que el resto de cámaras de esta segunda generación incorpora un puerto USB 3.2 de tipo C más robusto que los anteriores de tipo B.
La ampliación de memoria desde los 256MB hasta los 512MB DDR3 es otra de las mejoras de esta nueva gama de cámaras.
La QHY5III585C ya está disponible en algunas tiendas con un precio aproximado de unos 418€.

Intense moment frozen in time. Aurora framing the mountains in the background and Vikbutan Bay in the foreground, Lofoten Islands, Norway. The intensity of this display lasted for a short 10 minutes.
With humble excitement, I am pleased to announce that my piece, Intensity, which was also a 2020 PPA Gold Medal Winner, has been selected as Best of Show in the 9th Annual Photography Show of the Flagler County Art League by Juror, Eric Breitenbach.
“It’s not just the northern lights but the way their forms and shapes play off the landscape. The photographer made an astute selection of the location for composition and incorporated extraordinary technique for a once in a lifetime picture.” – Eric Breitenbach
This piece, along with three of my other works, (Reaching Out – Honorable Mention | Animals, Fading Mist (Vanishing Mist) – Honorable Mention | Land/Sea/Cityscapes, and Orange Glow) will be displayed alongside a richly talented cohort of fellow photographers, and can be viewed at: Flagler County Art League.

Unfortunately, with big sadness I just found out that one of our members is no longer among us. This is what Don Machholz’s wife announced on Don’s Facebook page:
It is with profound sadness that I share with everyone that my beloved husband, Don Machholz, passed away unexpectedly and swiftly from COVID at 3:15 AM on Tuesday, August 9, 2022. He was a very kind, gentle and loving soul, we love each other from the moon and back.
Don was a world famous comet hunter. He discovered as many as 12 comets during his lifetime and never gave up his passion. Until very recently Don would continue his comet hunting though visual observation.
Don spent more than 9,000 hours comet-hunting in a career spanning over 50 years. These comets include the periodic comets 96P/Machholz, 141P/Machholz, the non-periodic C/2004 Q2 (Machholz) that were visible with binoculars in the northern sky in 2004 and 2005, C/2010 F4 (Machholz), and C/2018 V1 (Machholz-Fujikawa-Iwamoto). In 1985, comet Machholz 1985-e, was discovered using a homemade cardboard telescope with a wide aperture, 10 inches across, that gave it a broader field of view than most commercial telescopes. Don utilized a variety of methods in his comet discoveries, in 1986 using 29×130 binoculars he discovered 96P/Machholz.
Don Machholz was one of the inventors of the Messier Marathon, which is a race to observe all the Messier objects in a single night.
The fascination of star gazing had already started during the very first years of my childhood. I was looking up at the night sky with my grandfather every summer night, studying constellations, the phases of the moon cycle, counting satellite passages and by using his binoculars to discover globular clusters of stars. Equipped with star maps from his home-library I was gradually discovering more and more of this fascinating world we call universe.
Even though years went by, the interest and fascination of cosmos had never left me… I found myself occupied with many other things before astronomy finally became my main hobby in recent years.
I was born in Stockholm, Sweden 1979 and grew for the most part of my childhood years in Greece. Later I’ve studied physics at Lund’s university and was hoping to continue with astronomy. At my free time I was an active amateur astronomer in South Sweden, Lund. At some point I was also appointed as chief of observatory for the Tycho Brahe Astronomy Society in Lund.
Circumstances in life led me to move with my family to California. Today I’m working as a sofrware developer within the aviation industry and weather systems for airports. During my off-time, I spend most of my time with my wife Melissa and our daughters.
My main hobbies are astronomy, astrophotography, game development and I was also a member of several astronomy societies in south Sweden but time was never enough to continue being an active member.
This blog is dedicated to my family (Melissa, Vanita and Lena Grace), our friends and to all of you who share the same fascination towards the beauty of this science and all the mysteries yet to be revealed by our constant discoveries!

After weeks of suffocating heat and smoke from the Tamarack, Beckworth, and Dixie fires, Aubrey and I decided it was time to make a trip the California coast, one of the only places within a 7 hour drive that could promise cool and clean air. We followed the long and windy roads to Salt Point State Park, one of my favorite stretches of coast that has the same strange rock formations you would expect to find in Utah. Ironically, though we came to breath fresh air, the sky itself was foggy most of the day and resembled the smoky skies from home. Still, simply knowing that the air was clean made all the difference, and sleeping in a tent in cold damp air was exactly the relief we’d hoped for.
The area is also quite popular with fishing and other harvesting. At one beach we met some friendly van lifers cleaning out their Sea Urchin haul, and I bravely nibbled on a piece of sea-to-mouth Uni they offered. It was extraordinarily delicate, sweet, fishy, salty, and nutty.
Bizarre sandstone shapes etched by millennia of wind, salt, and rain in Salt Point State Park, on California’s Pacific Coast. I used a long exposure (30 seconds) in this photograph to blur the misty sea to accentuate the strange figures.
We had visited here once before, but looking through my blogs that image never seems to have made it on here, so now seems like a good time to share it, too. The rocks here are covered in mesmerizing designs of tafoni, the same kind of weather rock found elsewhere along the coast, and in the southwest.
Intricate patterns of tafoni (the sculpted cave-like features on the sandstone) adorn the wild coastline of California, while the huge waves of the Pacific Ocean crash against the shore.
We have just returned from a memorable astrophotography trip at a Bortle 1 dark sky site. The event was an annual star party hosted by the Oklahoma City Astronomy Club known as the Okie-Tex Star Party.
After a few location changes during the first several years, the star party found its home at Camp Billy Joe near the small town of Kenton, OK, not far from the Oklahoma/Texas border. The name ‘Okie-Tex’ was selected to show the collaborative efforts of the two states.
Aside from taking some amazing astrophotography images through our telescopes, the event opened our eyes to the experience of being under a truly dark sky.
Arriving at the Okie-Tex Star Party
Camp Billy Joe is a very remote location away from all city light pollution. This also means that depending on where you live, you might have to drive (or fly) a long distance to get there.
We flew from Toronto to Dallas/Fort Worth where we boarded our connecting flight to Amarillo, Texas. From there, we rented a car and drove approximately 2.5 hours to the star party site.
When you arrive, you can check in (if registration is open) and then set up anywhere on the field. Like most star parties, your chances of getting a better spot are higher the earlier you arrive.
When traveling to the star party by car, there are significant distances between each of the small towns along the way. You’ll want to make sure you always have a lot of gas to avoid running out before the next gas station. There is no gas station in Kenton and the closest gas station to the star party is either Boise City, OK (36 miles) or Clayton, NM (43 miles).
It is always nice (and often easiest) to arrive at a new location in daylight. For our travel, we arranged for an early morning flight to arrive around dinner time to get settled and set up the first night. For our flight home, we made sure to book an afternoon flight to accommodate the long drive from the star party back to the Amarillo airport.
Where to Stay for the Okie-Tex Star Party
Like most star parties, camping is your easiest option for enjoying the star party. You can set up your gear outside your camper or tent and enjoy all the other activities and events on-site.
If you’d prefer a little more shelter or a bed while at Okie-Tex, they do have a limited number of bunkhouses available on a first come first serve basis. This includes a separate bunkhouse for men and women, as well as a family option.
Aside from the above options, there are limited alternatives for sleeping arrangements outside Camp Billy Joe. There is a small bed and breakfast nearby that we heard books up early.
As a speaker at the event, they arranged for a mobile home rental for us in the small town of Kenton, OK. This meant we had to drive the short distance (3 mins) to and from the star party and park outside the gates, which closed at 9 p.m. to avoid headlights or any type of white light once it was dark out.

Meals and Food Options
When you are so far removed from city amenities, the logistics for running a star party are more complicated.
In terms of food, there is catering available for those who are in a tent or staying offsite. There is a separate registration process and cost associated with this, so keep an eye out for this when completing registration.
If you’re looking for a late-night snack, the Cosmic Cafe is also available on-site each night from 10 p.m. until 2 a.m.
If you are camping, please note that open flames are not allowed for cooking (to discourage smoke and fire issues) but cookstoves are okay.
And if you’re up for a bit of a drive (approximately 45 minutes), there are also food options available in Boise City OK, and Clayton, NM.
Events at Okie-Tex Star Party
There are a lot of activities to do at the Okie-Tex Star Party besides astronomy or astrophotography.
There are plenty of great speakers lined up throughout the week and some additional workshops you can register for. There is also a swap meet, vendor tents, and some pretty awesome giveaways.
If you’re up for a little adventure, there are some other sightseeing activities that you can do in the area, including hiking the Black Mesa Summit, walking along a dormant volcano, and checking out preserved dinosaur tracks.
South View on top of Black Mesa Summit
Black Mesa Summit
We hiked the Black Mesa Summit which is only a short 10-15 minute drive from the star party. You can use Google Maps to get you to the parking lot and follow the trail to the top. Be sure to bring a backpack with water to keep you hydrated for the 9 mile trek and be on the look out for rattlesnakes.
Fun fact: Cimarron County, OK, which includes the Town of Kenton and the summit, is the only county in the U.S.A to touch 4 different states (Texas, New Mexico, Colorado, & Kansas).
You will want to make sure you leave plenty of time before dusk to complete the entire journey. It took us three hours to finish the 9-mile (14-kilometer) hike.
You will hike a long way (approx. 2 miles) before reaching the point of the hike where you actually start to ascend the Mesa.
Be sure to get your photo at the top of the summit, which is signified by a granite column. This is where you will see information about the 4 different states.
There is apparently a logbook at the base of the column as we later saw on social media. We did not sign it as we could have sworn the case it was in said ‘do not open’.
If you want the best view (and a view of the star party) but sure to follow a small path to the south. This will take you near the edge marked by two large wooden crosses. You can spot Kenton and to the left, the field of the star party. Again, be on the look for rattlesnakes that apparently like the tall grass.

Bortle 1 Skies
As a Bortle 1 site, the skies at Okie-Tex were incredible. We were lucky enough to have two crystal clear nights under the darkest skies I have ever seen.
Unfortunately, one of those nights was the day we arrived and we were, of course, exhausted from travel. With a half-day workshop the next day, I had to pack it in early. But the following night was also great.
We were told by the regular attendees of the Okie-Tex Star Party that some years have been very windy, but this was not the case for our trip. The skies were calm, cool, and most importantly, dark.

The scenic, rolling landscape at the Okie-Tex Star Party is well-suited for nightscape photography. Our host (Andy) spent much of his time at the party taking incredible nightscape images with creative compositions (including this incredible 360-degree view of the night sky).
I tried to capture as many Milky Way nightscape-style images as I could with my stationary tripod and filming camera (a stock Canon EOS R6). The following image is a single, 25-second exposure at ISO 3200 of the Milky Way from our campsite.

Deep-Sky Astrophotography Setup
Even though we flew, we were able to bring a fair amount of gear with us to take advantage of the dark skies. Because this was our first time under Bortle 1 skies, I did want to bring a little more focal length than I typically bring to a star party.
Below is the breakdown of the rig that I brought in my carry-on luggage and personal item (backpack). We did have to check one bag as our tripods did not fit in any of our carry-on bags. It also came in handy for packing some warmer clothing for at night.
Trevor (left) and Ashley’s (right) setup
I chose to photograph the Embryo Nebula in Perseus in LRGB. Unfortunately, the clearest nights of our trip landed at times when I had to present in the morning, and I didn’t run the rig as long as I wanted to.
My final image includes just 2.5 hours of total exposure time, using a ZWO ASI6200MM Pro camera and LRGB filters.

(Ashley has not yet processed her images of the Cave Nebula, but we will add those to the post when ready!)
When you are flying to a star party, you realize there are lots of other things that you typically bring to make things more comfortable, that you wouldn’t be able to given the circumstances – things like chairs, a table, a blanket, etc. Thankfully, Andy, from the Oklahoma City Astronomy Club had us covered, and brought all those things for us, including extension cords.
He even brought and set up a sky-box for us to have a little place to go during the star party, which also doubles as protection from the wind, which is common at Okie-Tex. He also kept an eye on our gear, so we could leave it set up, while we traveled to and from the town where we were staying. Thanks, Andy!

Star Party Speakers
In 2022, I was a speaker at the Okie-Tex Star Party. They expressed interest in having me attend in 2021, but due to the pandemic and the lockdowns between the Canada and USA border, it was arranged for the following year.
I presented on two topics: a half-day workshop on wide-field Astro imaging, and as per the request of the star party organizers, a presentation on the ZWO ASIAIR. Both talks went well and attendees seemed to be engaged in the information.
In addition to myself, there were other presentations from folks like Jonathan Talbot and Rick Fienberg on the topics of ‘Leveraging New CMOS Technology’, ‘Pixinsight Beginner Imaging’, ‘The New Era of Professional-Amateur Collaboration in Astronomy’ and ‘The Great North American Solar Eclipses of 2023 & 2024’.

Rules at Okie-Tex Star Party
As far as rules go, Okie-Tex is a pretty laid-back star party. They do have a few rules to follow, mostly pertaining to white light which is normal for a star party:
No white light after dark (laptops, cars, cell phones, etc.)
No laser pointers
Dim red light only and aim it at the ground
Anticipate your vehicle lights (opening and locking doors) and take the appropriate steps to make sure there are no issues with light
Park outside the gates after 9 p.m. if you are not staying overnight and park facing away from the star party
Pets are allowed but they must be leashed and contained at all times. Be sure to clean up after them.
Okie-Tex Star Party Impressions
This is a very relaxed and casual star party that doesn’t impact the amazing Bortle 1 skies. People just ‘get’ the rules (i.e. no white light) so all you need to do is show up, set up, and enjoy yourself.
The Oklahoma City Astronomy Club are great hosts. Being in such a remote location, it can be easy to feel a little uneasy, but they really do make sure you have all the comforts and necessities at the site – washrooms, showers, catering, power, etc. The star party is well organized and runs like you think a star party that has run for 30+ years would run – like a well-oiled machine.
The Okie-Tex Star Party from above.
There are a lot of seasoned attendees at this star party that make it a lot of fun. You can join in on the conversation, and get the scoop on their stories from the many years they have spent attending the star party and make new friends.
You’ll also want to be sure to hike to the top of the nearby rock formation adjacent to the star party to see Okie and Tex, the official flamingo mascots of the star party.
Overall, we had such a great time at the Okie-Tex star party and can definitely see ourselves returning in the future. A big thanks to the Oklahoma City Astronomy Club for the invite and for taking such good care of us!

The winners of the prestigious Landscape Photographer of the Year 2022 competition have been announced. Here’s a selection of our favourites
Landscape Photographer of the Year has now been running for 15 editions. Founded in 2006 by the hugely well-respected landscape photographer, Charlie Waite, each year the judges have the unenviable task of looking through many thousands of images to decide on the best of the best.
The competition is open to images of the United Kingdom, Isle of Man and the Channel Islands, but photographers can be of any nationality. As well as the main adult competition, a youth award runs alongside it, both sharing the same main categories – many of which you’ll see on these two spreads. The categories are Classic View, Urban Life, Black and White and Your View. There also special awards, comprising Coast, Historic Britain, Lines in the Landscape and Landscapes at Night.
One of the most prestigious competitions to be shortlisted in, it also has a prize fund worth more than £20,000 and culminates in a touring exhibition across the country.
Judges for this year’s competition include some of the leading names in photography and publishing – many of whom you’ll have seen in the pages of our magazine and online. Acclaimed photographers such as Lizzie Shepherd, Verity Milligan and Martin Evening are on the judging panel, as is our very own editor, Nigel Atherton.
The overall prize goes to William Davies, for his beautiful image of the Brecon Beacons in South Wales, while the overall Youth award goes to Natasha Burns for her beautiful shot taken in Argyll.
As well as a touring exhibition, a hardback book, published by Ilex Press, containing all of the winners, plus many more runners-up, highly commended, commended and shortlisted images, is available to buy.
For more information on the competition, the exhibition, the book and how to enter next year’s competition, visit www.lpoty.co.uk
See the winners below
Landscape Photographer of the Year overall winner 2022
William Davies – Brecon In Winter
Location: Brecon Beacons National Park, Wales
Canon EOS 5DSR, EF 70-200mm f/4L
Image: William Davies
Taken from the Pen-y-Crug hillfort, the viewpoint provides a stunning panorama of Brecon and the surrounding mountains in South Wales. William says, ‘On this December morning,
I arrived in the gloom before dawn but was lucky to find the sunlight soon breaking through a clearing in the snowstorm, adding a burst of warmth and colour to the scene.’ William used a telephoto lens, which has helped to compress the sunlit fields and the snow-covered hills and mountains in the background.
Landscape Photographer of the Year Overall Youth winner 2022
Natasha Burns – Dawn Reflection

Simon Turnball – Oh! Limpet Games
Location: Ayrmer Cove, Devon, England
Canon EOS 5D Mark III, EF 24-70mm f/2.8L
Image: Simon Turnball
Simon came across this fascinating scene while wandering along the Devon coast. He was immediately taken by its intriguing lines and colours, with the rock pool providing a wonderful composition and the limpets adding interest. He describes them as ‘playfully sliding down the gully like an Olympic bobsleigh team’.
Black and White category winner
Paul Killeen – Souls Tied
Location: Stranocum, County Antrim, Northern Ireland
Canon EOS 5D Mark IV, EF 70-300mm f/4-5.6L
Image: Paul Killeen
Paul’s beautifully peaceful image has a poignant message behind it. Taken on the same day as the funeral of a family friend, the two birds at the centre of the image reminded the photographer of his late friend Lynsey and her husband Simon.
Urban Life category winner
Kevin Williams – Fully Loaded
Location: The Port of Felixstowe, Suffolk, England
Nikon D810, 24-120mm f/4
Image: Kevin Williams
Kevin used a long exposure of 120 seconds to achieve this beautiful image.
Coast category winner
Gray Eaton – The Sacred Garden
Location: Anglesey, Wales
Nikon D3, 14mm f/2.8
Image: Gray Eaton
This tiny chapel – St Cwyfan – has been photographed many times. Inaccessible at high tide, Gray wanted to capture something that was a little different. In a single frame he wanted to show both the chapel and the aquatic world surrounding it, along with the submerged garden of algae.
Lines in the Landscape category winner
Damian Waters – Loch Awe
Location: Argyll and Bute, Scotland
Canon EOS 5D Mark IV, EF 17-40mm f/4
Image: Damian Waters
Damian planned this image before arriving at the scene, but discovered that the train was delayed on his arrival. He thought that the evening would close in too quickly, but just in the nick of time, the train emerged from the gloom.

I took my first two Ha images of Sh2-216 back in January 2017 and followed them up with some more in November. The initial results were shown here: http://andrewluck.me.uk/?p=1269.
Due to the extreme faintness of the object I’d opted to use 1 hour exposures for a total of 10 hours. Initial processing was enough to show detail in the nebula but the background showed some processing artifacts.
Fast forward to September 2020 and some clear sky opportunities lead to my acquiring another 7 hours of Ha exposures. As some online images showed some OIII in the nebula as well I added 17 hours of OIII images (1 hour images) and to complete the set a further 12 hours of RGB images (20 minutes each).
To combine the images I created an RGB image and then used the PixInsight NBRGBCombination script to blend in the Ha and OIII.
