Sigma 14mm F1.4 DG DN Art – Review 2023

[ad_1]

Astrophotography is one of the corners of the photo world that calls for specialized equipment, and the Sigma 14mm F1.4 DG DN Art ($1,599) fits that niche because of its bright maximum aperture, weather-sealed design, excellent handling of flare, manual focus lock, and heat retainer. The lens is also a good choice for landscapes, cityscapes, and other wide-angle subjects. However, the Editors’ Choice-winning Sigma 20mm F1.4 DG DN Art ($899) is more compelling because of its significantly lower price and similarly tuned optics.


Ultra-Wide Angle and Aperture

The Sigma 14mm F1.4 DG DN Art is the first lens we’ve seen with such a wide angle and aperture on a full-frame system. Sigma had a 14mm F1.8 DG HSM Art in the SLR days, and Sony markets the FE 14mm F1.8 GM ($1,599.99) today, but night sky photographers chase faster glass to help keep ISO and shutter combinations reasonable, as well as to more easily set focus. The Sigma 14mm is available for Sony cameras, as well as for L-Mount Alliance bodies.

The combination of a big f-stop and ultra-wide view makes for a hefty lens. The 14mm F1.4 DG DN Art’s 19-element, 15-group optical formula results in a 5.9-by-4.0-inch (HD) barrel and 2.6-pound weight. It’s a heavy lens to carry, especially if you’ve got others in your bag. If you don’t mind giving up a half-stop of light, the Sony FE 14mm F1.8 GM is downright small by comparison (3.3 by 3.9 inches, 1.0 pounds). For reference, Sigma’s 20mm F1.4 DG DN Art comes in at 3.5 by 4.5 inches, and 1.4 pounds.

Sony touts the FE 14mm F1.8 GM for astro work and it tests well for that discipline, but Sigma leans further into astro features here. The Sigma 14mm F1.4 is just as good at suppressing sagittal coma as the company’s 20mm F1.4 lens in the field, for instance. And, like the 20mm, it includes a manual focus lock and incorporates a heat retainer into its barrel (meaning you can add a lens heater to fight condensation without impacting the frame).

The barrel uses a mix of thermally stable composite (a high-grade plastic Sigma says is lighter but just as durable as aluminum) and magnesium in places where metal makes more sense. The 14mm is fully weather-sealed, and the front element includes an anti-smudge fluorine coat, so it’s ready for outdoor work. It’s too big to support front filters, but the lens includes a rear slot for gels.

Sigma includes a rotating tripod collar with an Arca-Swiss dovetail foot with the lens. You can remove it, but if you plan on using a tripod (a requirement for night sky work), you should use the lens mount as the attachment point, not your camera (the lens is front-heavy). Sigma also includes a rubber beauty ring in the box to replace the collar for those times you don’t need it, along with a soft carrying pouch and a slip-on front cap that protects the lens.

One other note: Sigma warns photographers with pacemakers to be careful with the 14mm F1.4. The lens includes a magnet, so you should keep it at least two inches away from your chest to avoid complications. If you’re concerned, you should talk to your doctor about how this might affect your health.


Controls for Night Sky Work

The 14mm F1.4 Art has all of the controls I expect from a modern high-end lens. The on-barrel aperture ring toggles between third-stop detent clicks and smooth, silent turns. It also includes an “A” position if you want to move aperture control to the camera body. The aperture lock switch lets you keep the lens set at either “A” or in its manual range but doesn’t go as far as to lock the lens down at a particular f-stop.

It’s easy to toggle the focus mode via the AF/MF toggle, and you can use the function button just below it to drive or lock focus, depending on how you set up your camera. The manual focus experience was pleasing, and the bright aperture made it pretty easy to lock focus on distant stars, even with my first-generation Sony a7R IV and its so-so rear LCD. I made sure to engage the Manual Focus Lock switch once I had focus set perfectly, which gave me the freedom to move my tripod around and try different frames.

Autofocus is as quick as I’ve seen on the a7R IV. The 14mm F1.4 uses a linear HLA focus motor that racks focus instantly and silently. The lens calls for a serious gimbal like the DJI RS 3 for video work but does a good job for point-of-view and other special effects shots. Some focus breathing is visible, however: The angle of view is slightly wider when you focus on a nearby subject. You might notice the change in rack focus shots that shift perspective for dramatic effect, but it won’t detract from takes with moderate shifts to focus.

Despite a design tilted toward night sky work, the 14mm F1.4 does a decent job with close-up subjects (even though it falls well outside of the macro realm). It focuses as close as 11.8 inches away from the sensor for 1:11.9 reproduction. The broad view makes for interesting close-up effect shots that show an especially broad range of your surroundings. The working distance from the front element is around three inches, though, so make sure not to shade your subject.


Sigma 14mm F1.4 Art: In the Lab

I tested the 14mm F1.4’s resolution using our standard method—tightly framing and photographing a transmissive SFRPlus test chart. There’s a slight complication in this case though: You must perform this test at a close distance with a wide lens and Sigma’s technical documentation cautions that the lens doesn’t perform as well at focus distances of less than 6.6ft (2m). This makes sense because test charts are flat, and the 14mm’s bulbous optics capture a field of focus with a decided curve. As a result, sharpness results away from the center are artificially low. This characteristic is not a problem when you focus on distant objects (the stars in the night sky are more than a couple of meters away). And for closer subjects, either using a wide aperture to induce background blur or increasing the depth of field mitigates this issue.

At f/1.4, the 14mm shows an excellent 4,400 lines at the center of the Sony a7R IV’s 60MP sensor. Off-center sharpness drops quickly, as I expect from a lens with field curvature. The center gets better at f/2, showing an outstanding 5,000 lines, and maintains that level of quality through f/11. There’s a drop in picture quality at f/16, a result of diffraction, but I still see very good results (4,000 lines) in the central area of the frame. You might still want to stop all the way down to get sunstars; the 14mm draws crisp 22-point starbursts at its minimum aperture.

To supplement the close-up lab charts, I made some boring images of a wide paved walkway, with the point of focus set further out. In this sequence, the lens shows softness at the edges and corners at f/1.4 and f/2, but edges are clear starting at f/2.8, and tack sharp from f/5.6-11. Thus, the 14mm F1.4 is more than capable for landscapes.

At wide apertures, the 14mm F1.4 handles backlit situations and flare quite well. I made some images into the sun with it just out of frame and the integrated hood and anti-reflective coatings helped images maintain good contrast. I couldn’t spot any evidence of ghosts or false color at wide apertures, but I did notice some reflections when I tested at f/16 for sunstars.

The optics show some barrel distortion and a vignette without corrections or a Raw profile. You won’t have to worry about this if you use your camera in JPG mode, but for Raw photography, make sure to enable any correction profiles to brighten edges and eliminate visible barrel distortion.

I also used the lens for some night sky photography: The lens is a technical star here (pardon the pun). It draws stars in the night sky as perfect pinpoints through most of the frame. I can spot some sagittal coma at the corners of the frame, an effect that draws stars as crosshatches with some false color rather than a pinpoint of light, but it’s no worse here than it is with the 20mm F1.4 DG DN Art. The biggest challenge I had was finding an interesting frame. The trees in my yard are a little too dense for an unobstructed view of the sky, and suburbia doesn’t lend itself to epic astro-landscape shots like you get from the dark, open skies of more remote locales. It’s a real shame that I couldn’t try this one out at Arches or Yosemite.

At near distances, it’s possible to induce some background blur. A 14mm is not my first choice for close-ups because it’s hard to find an angle that doesn’t introduce a distorted perspective, but you can certainly use it for a blurred background effect. The defocused highlights, or bokeh, is very pleasing: They are rounded, have soft edges, and are free of distracting onion skin and LoCa false color.


An Ultra-Wide Lens for Night Sky Photographers

There’s good reason for astrophotographers to get excited about the Sigma 14mm F1.4 DG DN Art. The lens is the broadest full-frame optic with an f/1.4 aperture for any system, and its on-barrel controls suit night sky work well. It also focuses quickly, shows minimal sagittal coma, and is fully weather-sealed. For the same price, the Sony FE 14mm F1.8 GM is more practical to carry, but it doesn’t have as many astro-specific features such as a manual focus lock. Therefore, Sigma’s 20mm F1.4 DG DN Art remains our Editors’ Choice winner for astrophotography primes; it’s a lot more affordable than either of the aforementioned 14mm lenses and still covers a wide angle.

Those are all specialty lenses for astrophotography, though. If you don’t care about night sky photos, the Editors’ Choice-winning Sigma 14-24mm F2.8 DG DN Art ($1,199) is a more practical ultra-wide zoom that’s also available for both E- and L-mount. And Sony owners can go even wider with the FE 12-24mm F4 G OSS ($1,774.99).

Star clouds, nebulae, oddballs at galaxy’s core

[ad_1]

July’s night skies are legendary for their sheer abundance of celestial objects such as immense star clouds, light and dark nebulae, crowded clusters and oddities.

Daniel Zantzinger / Skywatcher's Guide
Daniel Zantzinger / Skywatcher’s Guide

By midnight all month, the Milky Way galaxy stretches from below the southern horizon to high overhead before plunging into the northeastern abyss. The stellar cascade soars above and beyond, so these nights are primed for long exposure astrophotography and time-lapse videos.

Constellation Scorpius reaches its highest point above the southern horizon for the year — culminates — when it straddles the north/south meridian 9 p.m. July 20. To its east lies Constellation Sagittarius, which culminates next month. When you look between the two constellations, you’re looking in the direction of the unseen bulging center of the Milky Way. As a point of reference, the exquisite Butterfly Nebula (NGC 6302) follows the most direct line of sight to the core.

Scorpius and Sagittarius are home to light nebulae including emission, reflection and planetary nebulae, as well as dark nebulae known as Barnard objects, which are essentially dense patches of gas and dust blocking starlight from behind.

Under dark and clear skies, it’s easy to become awestruck in this dense and diverse neighborhood even with the naked eye. The scorpion asterism alone has 182 visible stars. The other objects here, however, are best resolved and teased out from their compact concentrations with at least a small telescope. Image-stabilized 10×50 binoculars will also provide sufficient in-depth focus.

Find Antares, the heart star of Scorpius, a bright and unmissable red supergiant in the center of the asterism. With a telescope, zero in to observe the delicate nebulosity of Messier object 4, the Rho-Ophiuchus cloud complex illuminated by Antares and neighboring stars. With the naked eye, look east above the hook-shaped stinger to find the Ptolemy Cluster (M7), an open star cluster of about 80 scattered blue stars.

The reason that this part of the sky is so target rich is because three or more bands — arms — of the galaxy overlap. “Or more” because, as is often the case with clouds, it’s often difficult to visually determine where one stops and another starts. Nevertheless, the principals are the Sagittarius-Carina, Scutum-Centaurus and Perseus arms.

The center of the Milky Way is for the most part obscured by dense clouds of gas and dust that block visible light. There are, however, a few significant gaps in the veil — Baade’s Window for one — that allow skywatchers to observe some of the inner structures.

East of Scorpius the skywatcher enters Sagittarius, the superlative centaur Chiron to the ancient Greeks and the archer god Nergal to the Babylonians. This is high-end real estate for vast star clouds and stunning nebulae. The Large Sagittarius Star Cloud is the brightest stretch of road along the Milky Way and the innermost galactic structure that can be observed in visible wavelengths. It is iconic and easily recognizable by its dark nebulae rift lanes of light-obscuring molecular clouds composed of hydrogen gas with a blend of about 150 exotic species of dust. Note that it’s only due to the existence of Baade’s Window that we can see the large star cloud at all.

In Sagittarius, look for the famous Lagoon (M8), Omega (M17) and North America (NGC 7000) light emission nebulae. The Trifid Nebula (M20) is a hybrid of both light and dark nebulae: a luminous star-forming area trifurcated by a lobed dark nebula cataloged as Barnard 85.

Constellation Ophiuchus, the serpent-bearer, due north of Scorpius, culminates at 9 p.m. July 25. Dark nebulae hunters will find ample prey near the Sagittarius-Ophiuchus boundary and within Ophiuchus itself. This frontier holds myriad highly complex Barnard objects. The Dark Horse and Rider is composed of the Pipe Nebula, the hind quarters and back leg of the horse. Barnard 63 is the front leg, B270 is the horse’s head and B276 is the rider’s head.

Ophiuchus (pronounced oh-fee-YOU-kuss) also rewards skywatchers with its multitude of star clusters, the most impressive of which are M9 and M10. Called globular clusters because of their spherical shapes, they contain at minimum tens of thousands of stars in an extremely compressed area. M12, M62 and M107 are outstanding sights as well.

Look for NGC 6240, the oddball Starfish Galaxy, a merger remnant on the center-right of the asterism. A starburst galaxy of intense star birthing activity, it formed when three smaller galaxies slowly merged over several billion years, and now resembles a starfish. This lenticular galaxy retains their original three nuclei and native black holes, two of which are expected to eventually merge into a supermassive black hole.

Even though the Milky Way is “our home galaxy,” its heart is impossibly far away. To put things into perspective, Antares is 554.5 light years from the Sun. One light year is 5.88 trillion miles, so traveling even near the speed of light it would take more than 40 generations of astronauts to arrive at Antares. The center of the Milky Way is 26,000 light years away, so its light arriving today left it during the peak of the ice age’s Last Glacial Maximum.

The moon is full 9:41 p.m. July 3 and is called the Full Buck Moon, a reference to the mature growth of male deer antlers.

Astrophotography in July 2023: what to shoot in the night sky this coming month

[ad_1]

With little or no astronomical darkness at the start of July in northern latitudes, some astrophotographers might think this month is a write-off for creating night sky images. Not so! July is one of the best few months of the year to get the Milky Way high in the sky as seen from the northern hemisphere – and, crucially, its bright center – while July’s full ‘Super Buck Moon’ is one of the brightest yet lowest-hanging of the year. 

Add plenty of conjunctions between the planets and the moon, the year’s first so-called supermoon, the peak of the Delta Aquariids meteor shower and 2023’s second ‘Manhattanhenge’ for New Yorkers and there’s plenty more to get excited about for astrophotographers in July 2023.

Google Pixel Fold First Impressions

[ad_1]

While I am an adherent to the “right tool for the job” principle, I am also open to a single device that can replace two other devices. So far, my experience has been mixed: while the iPhone and Android smartphones made dedicated music players like the iPod superfluous, their small displays make them less than ideal for reading or watching videos (at least to my eyes). You win some, you lose some.

But with folding smartphones, the promise is that this one device will be so good for reading and watching videos that it will eliminate the need for a standalone tablet while making phone-centric tasks like email, maps, social media, workplace collaboration, and so on even more immersive and enjoyable. If it works, it’s the best of both worlds. If it doesn’t, well. We’ve been there before.

Folding smartphones have run into some obvious headwinds, of course. They’re very expensive, often twice as expensive as a typical flagship smartphone. The folding display technology has had reliability and durability issues. Developers have been slow to adapt their Android apps to the unique benefits of this form factor. And folding phones, while elegant and fun while open, are thick and heavy when closed, and they don’t close flat. Compromises are everywhere.

And given Google’s unfortunately spotty record with hardware quality, it’s reasonable to question how this company could possibly succeed where its more experienced competitors—mostly Samsung—have so far been hit or miss. It’s certainly been at the top of my mind, and never more so than when my $1900 credit card purchase was completed on Monday as Google shipped its first folding smartphone, the Pixel Fold, to my home.

And … wow.

Put simply, I think I may be looking at the future of smartphones here. Not so much in Google’s v1 outing, which is far too expensive to ever be mainstream, but rather in the way that the online giant pulled an Apple, observed what has worked and not worked in previous folding smartphone designs, waited until it could do better, and then finally pulled the trigger.

In real-world terms, this means that the Pixel Fold is thin—about half an inch or so—for a folding phone while closed, making it feel less chunky and awkward than Samsung’s offerings, and easily pocketable. It also closes flat, with no air gap, and because it features the instant classic Pixel camera bar across its back, you can use it normally, if slightly angled, on a table when closed. (When open, you get some wobble.) And the outside display, while small at just 5.8 inches, mostly fills up the exterior of the device, and is not oddly tall and thin like Samsung’s, helping it look and feel more natural as a smartphone.

When unfolded, the Pixel Fold is unbelievably thin, much thinner than any of my smartphones. Its internal folding display is expansive and a welcome sight to my middle-aged eyes. It’s like a 7.6-inch mini-tablet with a blessedly square (6:5) aspect ratio that I wish Google has used for the Pixel Tablet as well. But that’s the magic here, a big part of why it feels like the future: this is a smartphone that is small and thin enough to fit fine in my front pocket, but it also opens up like a flower into an even thinner device with a much bigger display that is ideal for consuming content. It’s not just two things in one, it’s two useful things in one.

What everyone is probably most interested in is the folding bit. That is, how well does the hinge work and how much rumpling can one see on the screen’s crease? Here, I have mostly good news with the caveat that I just got the thing: the hinge is fantastic and something the Surface team would brag about incessantly, and the folding display is, well, a folding display. You can see the crease clearly when the device is off, but it’s not obnoxious and it does seem to disappear when fully open, depending on the app. Or, apps: when you use two apps side-by-side, the crease disappears as well.

As a Pixel fan, I like how Google has also blended the best of its smartphone platform with this new form factor. Obviously, Pixel Fold benefits from the same work on large-screen Android compatibility as with Pixel Tablet. But unlike with the tablet, the cameras here really matter—they’re not quite as good as the setup you get with Pixel 7 Pro, but close—and you can take selfies with the main cameras thanks to the external display. And can take astrophotography shots without needing a tripod because the device can be angled to the stars and kept steady with that rock-solid hinge. Nice.

The basics are, well, basic. You get the same clean Android image as on other Pixels with the same AI benefits, and the same basic UI found on the Pixel Tablet (when the Fold is open). And I really like its industrial design. But you also get the same acceptable but uninspiring performance, I’d imagine, and I’d be shocked if the battery life was any good given how much trouble my Pixel 7 Pro has getting through a day. (The Pixel 7 Pro has a bigger battery than the dual-screen Pixel Fold, too.) I will find out.

The question before us, then, is whether a Pixel Fold is an acceptable replacement for a Pixel 7 Pro and a Pixel Tablet (or maybe an iPad Mini, if you’re looking for a tablet a little closer in size). Wherever you fall in this debate, the issues I see are price and battery. A Pixel 7 Pro ($900) and Pixel Tablet ($500) are together less expensive ($1400) by hundreds of dollars, and each has its own battery. But then again, you can’t stick a Pixel Tablet in your pocket, can you?

I’ll spend some more time with Pixel Fold and report back soon.

The Cherry Springs Star Party is a Stargazing Paradise

[ad_1]

The Cherry Springs Star Party has become an increasingly popular destination for stargazers along the east coast, for good reason. Now that the word is out about the pristine skies of Cherry Springs, the event sells out quicker every year. 

It is held at a state park between Coudersport and Galeton in Potter County, Pennsylvania during the new moon in June. 

It takes place on the overnight observing field at Cherry Springs State Park, which sits at 2,300 ft. elevation. The field offers great views of the core of the Milky Way and a 360-degree view of the night sky. 

Cherry Springs State Park is an International Dark Sky Park and one of the darkest locations on the east coast. Its dark skies are protected by the undeveloped forest around the park and the shielded lights from the nearby communities.

Since this is the closest Dark Sky Park to us, we try to attend this star party every year. It takes us roughly 4 hours to get there and it’s well worth the drive for the Bortle 2 skies. 

Arriving at Cherry Springs Star Party

Registration for Cherry Springs typically opens in March and has sold out quickly the last few years. At the time of writing this post, registration is just over $55 USD per person. That includes camping on the overnight observing field for the duration of the star party, access to power for your gear, and a great lineup of scheduled talks and activities.

After registering, you will receive a confirmation email with your digital tickets. It’s a good idea to print those out and bring them with you to the star party for checking in at the front gate upon arrival. 

The star party typically runs from Thursday – Sunday. If you decide to show up early (or stay later), you will be required to pay the state park fees for the extra days that you decide to stay.

When you arrive, you get a package with a schedule of events, star party rules, and a ticket for the raffle. 

Camping at the Cherry Springs Star Party (2022)

Where to Stay for the Cherry Springs Star Party

As mentioned in other star party posts, it’s always easier to camp on-site at the star party. This is one of the locations that we can drive to and therefore, we love camping on the field with our camper, Voyager 1.

There are three areas available for stargazing, though only one is associated with the star party. 

  • Overnight Astronomy Observation Field: this is where the star party is held. Your registration includes access to this field for excellent overnight viewing.  White light is prohibited in this area and only dim, red lights can be used. 
  • Night Sky Public Viewing Area: this operates like a drop-in/short-term stargazing experience and is located across the road from the overnight observation field. Lighting restrictions are not enforced here, though, for your own observing experience, you may want to have a red filter or cover for your flashlight to preserve your night vision.
  • Rustic Campground: also across the road from the observing field, there is a campground for overnight stargazing for casual stargazers. Because there are no lighting restrictions, this area is not recommended for serious stargazers.

Please note, there are no showers on site. If you are camping, and need access to showers, there are some available at Lyman Run State Park (6 miles away) for a small fee.

In addition to the options above, some people opt to set up their equipment on the star party observing field and stay off site at a nearby hotel. If you choose this option, be sure to park your vehicle across the road in the public parking area before dark. The gates close at dusk and there will be no in or out on the observing field. 

Meals and Food Options

If you are camping, consider that open flames are not permitted on the field. This will impact what you pack for food. If you have a cooler with food, there are nearby options to buy ice (like the Cherry Springs Country Store). Be mindful of bears in the area and be sure to store your food and cooler in your vehicle. 

There is also a food vendor on site. They are open for breakfast, lunch, and dinner, in addition to their late-night hours until 2 a.m. for coffee and light snacks. Like the rest of the star party, the food vendor tent will be decorated with red lights. 

The town of Coudersport is also a 21-minute drive and has additional food options. There are other (smaller) options available in the immediate vicinity of the park. 

Events at Cherry Springs Star Party

There are two days (Friday/Saturday) packed with activities at the star party, including:

  • Speakers: there are multiple speakers throughout Friday/Saturday. You can check the schedule for times, topics and speaker bios. 
  • Gear Swap: bring your old gear to swap or sell at the event. Check the schedule for when this event takes place.
  • Raffle: there is a door prize raffle with tons of prizes. Be sure to get your ticket when you register and check the schedule for the deadline for submitting your ticket(s). Like most raffles, you must be present to win. 

In addition to the onsite activities, there are other nearby attractions, such as other state parks and an Ice Mine

What to Bring

In addition to your gear, you are going to want to make sure you are prepared for the cool weather.

As mentioned, Cherry Springs State Park is located on a mountain, which means the weather is generally cooler and can get very damp. Even though the event is held in June, you will want to make sure you bring plenty of warm clothes, including warm footwear and a heavy jacket.

It also helps to have things like blankets, lawn chairs, binoculars, and tarps or telescope covers for your equipment. 

 

Unspoiled Dark Skies

The dark, Bortle Scale class 2 skies of Cherry Springs are incredible. This site is dark enough for Venus to cast a shadow, and zodiacal light is visible on a good night.

On a particularly incredible night at Cherry Springs (during the Black Forest Star Party in the fall), I was able to see the Triangulum Galaxy with my naked eye.

The timing of the Cherry Springs Star Party in June means that it is the perfect time to watch the Milky Way core rising above the southeastern horizon.

Milky Way photography and nightscape photography are popular choices at this event. It is also a great location to take a timelapse of the night sky with a sea of red lights below.

One of the most enjoyable experiences at Cherry Springs is simply lying down in a zero-gravity chair and looking up.

You do not need a telescope to enjoy the skies at Cherry Springs, your naked eye will reveal countless stars and even bright nebulae when your eyes have adapted to the darkness. 

Deep-Sky Astrophotography

While at the Cherry Springs Star Party, we like to take advantage of the dark skies and shoot unfiltered, often going after something in the core of the Milky Way. 

It is wise to take advantage of the dark, new moon skies of the Cherry Springs Star Party, and capture a deep-sky object that is not possible to shoot from home. 

This means that narrowband imaging is not a practical choice, as this type of astrophotography can be done successfully in areas with heavy light pollution.

Instead, focus on more challenging broadband targets such as dark nebulae, or reflection nebulae that require dark skies and plenty of exposure time to capture. 

We have shot a variety of targets from this location, including:

Rho Ophiuchi Cloud Complex taken by Ashley at Cherry Springs (2022).

When taking pictures from this park, I usually take exposures of about 2 minutes long depending on the target I am shooting.

With quality dark skies like this, an integration of 1-hour will provide a healthy signal-to-noise ratio, with an incredibly clean image.

A typical deep-sky project from this location includes 2-3 hours of total exposure time, using exposures between 90-120 seconds each.

Rules at Cherry Springs

Like most star parties, there are rules for ensuring that everyone enjoys their star party experience. Below are the rules for the Cherry Springs Star Party. 

  • No Driving after sunset: the front gate to the observing field will close at dusk and reopen at dawn. Always follow the posted speed limit when driving in the park.
  • No campfires: no open flames allowed on the overnight observing field. 
  • No white light: Dim red lights only after sunset, no white light allowed after dark. This includes interior and exterior lighting for cars, tents and RVs, and electronics. 
  • Electric pedestals on the field are for powering astronomical equipment, computers and small appliances only. 

Cherry Spring Star Party Impressions

The folks at the Astronomical Society of Harrisburg throw a great star party. It is always really well organized, with plenty of communication and signage leading up to and at the event. Staff are around throughout the duration of the star party and are always very welcoming.

It is also a prime location for capturing the core of the Milky Way with great views of many of the summer constellations and deep-sky objects. 

After coming for many years, this has become one of our favorite star parties. We love that we can enjoy the full star party experience camping on the field in our camper and get the chance to meet many new (and often repeat) astrophotographers and visual astronomers. It’s a great place to ‘geek out’ and talk shop about astronomy.

For amateur astronomers, ‘star parties’ are the antidote to light-polluted skies

COUDERSPORT, Pa. — Up a winding road that cuts through the Allegheny Plateau, hundreds of amateur astronomers in campers and pickups stream into northern Pennsylvania each spring and summer in search of one thing: stars.

It’s something they can’t get enough of in the halo of light pollution that surrounds most cities. By contrast, Cherry Springs State Park, located about 135 miles northwest of Wilkes-Barre, is one of the very few truly dark sky sites in the entire eastern United States.

Twice a year, in June and September, park officials and local astronomy clubs team up to host “star parties” that draw people from as far away as Florida and Wisconsin. For these amateur astronomers, there’s no replacement for the inky-black skies that reveal what they affectionately refer to as “faint fuzzies” — dim and distant galaxies, star clusters and nebulae.

The weather, however, is always a wild card. Only the third and final night of the June event this year, timed to coincide with the new moon, delivers clear skies. Molly Wakeling is betting that will be enough to capture LDN 1262, a wispy nebula in the constellation Cepheus. She’s hoping to photograph it, something that would be impossible from her home in Dayton, Ohio.

“I do the objects from the dark skies that are hard for me to do from home,” Wakeling says. A quick glance at a dark sky map makes clear why western Ohio is such a challenge for her, and why Cherry Springs is so inviting, even if it means waiting out clouds and rain.

Digital cameras have changed the game

Wakeling is part of a growing trend among amateur stargazers. Traditionally, “visual astronomers” have simply looked through an eyepiece to view objects that are often thousands — or even millions — of light-years away. In recent years, however, sensitive digital cameras have brought amateur astrophotography into its own. Long and multiple exposures collect much more light than the human eye and can then be “stacked” to assemble extraordinary images, as evidenced by Wakeling’s online gallery.

Eric Roth, a past president of the Astronomical Society of Harrisburg, which organizes the annual star party, says 550 people registered for this year’s event, with another 400 on a waitlist. That tops the previous record set in 2022. He says the switch from visual astronomy to astrophotography is “a big-time change” that seems to have really taken off around the start of the COVID-19 pandemic.

Roth considers himself an old-school, through-the-eyepiece “strictly visual astronomer.” But today “it seems like everybody is going now for astrophotography.”

He doesn’t think that is a bad thing. It’s helping pass the amateur astronomy baton to a new generation. “We’re skewing younger than we used to, which is good,” Roth says. He surmises that it’s because the gadgetry of astrophotography appeals more to a younger demographic.

Trinna Cuellar, 41, lives in New Jersey and has also recently gotten into astrophotography. She talks about her telescope gear the way some people talk about a prized sports car — citing specs and rattling off lingo.

Cuellar has brought her son, Lev, who is almost 11, to Cherry Springs so he can get his first glimpse of “the galaxy we live in” — the Milky Way, she says.

She was first at Cherry Springs as a child and credits the experience with sparking her interest in astronomy. “My first time here, I think I was 7 or 8 years old,” she says. “We came to see the stars, and I was just blown away.”

A few years ago, at the start of the pandemic, she took the leap into astrophotography.

“I love the creative freedom,” Cuellar says. “There’s a lot of flexibility in how you put together that final image.”

“I can actually create something that kind of resembles a Hubble image,” she says, referencing NASA’s famed Hubble Space Telescope.

An escape from light pollution

While the dark skies of Cherry Springs benefit all amateur astronomers, with filters and other workarounds, astrophotographers can mitigate some of the light pollution issues they experience at home. For visual astronomers such as 69-year-old Wayne Petko, though, dark skies are a must.

That’s why he’s been coming to Cherry Springs from his home in New Jersey for the past quarter-century — and not just for star parties but for new moons throughout the summer, when there’s usually 50 to 100 other enthusiasts on the observing field with him, he says.

Petko belongs to the New Jersey Astronomical Association, whose observatory is at a state park situated west of New York City and about 40 miles north of Trenton, where “there’s been a gradual upswing in light pollution.”

In fact, Petko’s observation about an upsurge in light pollution is backed by data. A study published earlier this year in the journal Science indicates that on average, the night sky has gotten nearly 10% brighter each year from 2011 to 2022.

That would probably come as no surprise to Stephen Alba, who lives “15 minutes from Newark Airport,” where the stars are hidden by a hazy glow. He, his wife and young son arrived at the Cherry Springs party without a truck full of complicated astronomy gear — just a simple pair of binoculars.

“We want to see the Milky Way,” Alba says, smiling. “We’re just here to experience it.”

Shooting the moon – Twin Cities

[ad_1]

Over the next two weeks, the moon will be very prominent in our sky, starting as a first quarter (half moon) on Monday and becoming a full moon a week later on July 3. It will be the first full moon of the astronomical summer. Without a doubt, moonlight, especially full moonlight, louse up the skies for good stargazing and astrophotography, which are near and dear to me. Despite that, I love, love, love full moons! I call it my magic moon time.

I love the names given to full moons by various cultures worldwide. One Native American name for the July full moon is the Full Buck Moon because this is when buck deer begin sprouting new antlers. It’s also called the Thunder Moon because of the more frequent thunderstorms this time of year. My favorite name for the July full moon comes from the ancient Chinese Buddhist tradition. They called it the Hungry Ghost Moon. I am still trying to figure out why.

Whatever you call the July full moon, you can’t help but notice that it’s a low rider and doesn’t rise very high in the sky. That’s one of the reasons I love full-moon gazing this time of year. You can moon gaze for an extended time without extending your neck as much!

Not only is it nice to take in the July moon, but you can also have a lot of fun taking pictures of it. You don’t need a fancy camera; even your cell phone can do a pretty good job if you do it right. A zoom lens and exposure control can help so the image doesn’t get washed out.

You can take fantastic moon pictures through a small to moderate telescope. Hold your camera or phone over the eyepiece as steady as possible, which can be challenging. I suggest you keep hitting the shutter button or icon; hopefully, you’ll get some decent shots. If possible, rig up a tripod or something else to help steady your camera or phone over the eyepiece. You can also purchase an adapter that attaches to your telescope and eyepiece. One I recommend is the Orion SteadyPix EZ Smartphone Telescope Photo Adapter

Along with keeping the telescope steady, another essential thing is to start taking your shots through a low-magnification eyepiece with your telescope. That will have a much wider aperture than a high-magnification eyepiece. Once you get some low-magnification photos, see what you can do with a higher power.

Full moons are not my favorite to photograph through a telescope; I prefer pictures of the moon at other phases in its monthly cycle. Crescent moons, half moons, and even gibbous (football-shaped) moons are all fun to photograph. You can see more detail, especially what’s known as the terminator. That line divides the moon’s sunlit part and the part in shadow.

Once you get the photos, you can work with them a little in Photoshop or some other software, even within many smartphones, to make them look even brighter or sharper, although you shouldn’t have to do too much. You can also do some editing just with your phone. I was just amazed by the clarity. You can see details in the dark maria or plains on the moon and the mountains and craters, suitable enough to frame and hang on a wall in your home!

While you’re moon shooting or just moon gazing in the early evening eastern sky check out the low western sky. The very bright planet Venus and the much fainter Mars are in a close celestial conjunction or what I call a celestial hugging. On Friday, June 30, Mars will be just a little over three and a half degrees to the upper left of Venus. That’s about half the width of your fist at arm’s length. Just to the upper left of Mars is the moderately bright star Regulus.

Google Pixel Fold review: Google nails the foldable experience in all the best ways

[ad_1]

Two-minute preview

The Google Pixel Fold arrives a little late to the foldable party but, based on my time with the device, it’s a smartphone/tablet combo that mostly delights, and which is sure to earn a place among our ranking of the best Foldable Phones.

From its construction, including its precision hinge, to its high-resolution screens, the Pixel Fold is a well-thought-out Android phone that’s equally at home as a small-screen, but thick, 5.8-inch phone or, unfolded, as a 7.6-inch mini tablet.
