Photo is a blend of Sky and Land. Sky processed by Sequator. 30 frames x 30sec. No calibration frames. Class 6 on Bortle scale.
The colorful gems found within the constellation Auriga include colorful nebulae such as IC 405 (The Flaming Star), IC 410 (The Tadpoles), IC 417 (The Spider & Fly), and emission/reflection nebula NGC 1931. This region also includes open star clusters NGC 1912, NGC 1907, and NGC 1893. Several colorful larger stars are also present adding even more color to this star-dense region on the edge of the Winter Milky Way arm, located roughly between the Pleiades and Orion. This image was captured on 11/5/21 and consists of 23 x 5' exposures shot with a Nikon D750 and Rokinon 135mm lens. Exposure settings used were f/3.2 and ISO 1600. Processed using Rawtherapee, Sequator, rnc-color-stretch, and Adobe Photoshop/Lightroom.

My first attempt at stacking. Sequence of 5 second exposures with Fuji X-T1 and Samyang 50mm F1.2 at f/1.4, no tracker. Some small clouds passing created the horizontal bands, but I like it actually.

Shot using Sony A7 III (ISO3200, 10s) and Sony GM 24mm (f/1.4). 720 frames shot, but a number of them had to be thrown away due to airplanes and wind gusts (my first time seeing it affecting wide angle shots...). Pre-processed using RawTherapee, startrails assembled using StarStaX and final post-processing using RawTherapee
[ NO STACKING ] refers to the fact that Sequator was not involved here, unlike with Celestial North Pole image (but I am intending to try it out later on and publish here for comparison)

M31 the Andromeda Galaxy with comet 12P/PonsBrooks taken on 3rd March 2024. The pink at the bottom is part of the amazing aurora we had that night! Widefield shot taken from Oxfordshire with a Canon 1100D + 50mm fixed lens, 20 x 10 seconds + 20 darks stacked using Sequator. Sequator doesn't have a comet stacking mode but at such a short focal length the comet had moved so little in the time I was imaging that I just stacked on the stars and it looked good.
This is median stacking *without* sequator. The mount was tracking Orion, and because it was alt-az and the camera wide-angle (14mm), the frame rotated relative to the sky with time. The median operation took out moving objects, leaving a weird sort of bokeh for everything that isn't Orion.

Trying to capture the milkyway with the Nikon 8-15mm fisheye lens.. 12x30 sec ISO 800 shots stacked in Sequator. Some post-processing. Unfortunately, with the wide angle the stars in the south (bottom of the image) are not sharp enough for my liking. I should have used a tracker. Still learning...
And then there is a strange darker stripe at 3 o'clock - which I also see on single shots. I don't think this was in the atmosphere but perhaps has something to do with the lens or camera?
Comet Tsuchinshan-ATLAS 22nd Oct 2024, 35 x 20 second exposures (11 minutes 40 secs) were captured to create this view. Canon 7D mk2, 18mm lens at ISO1600. Stacked using Sequator V2 (my first time using this great software).

Staying with friends in Le Morvan, France, where it is really DARK at night, I could not resist trying a star trails shot - what do you think?

Mars, Saturn, Antares, Jupiter and the Galactic Center of the Milky Way. Shot in the Hocking Hills area in South Central Ohio. Bortle scale 4. This is created from 13, 15 second, ISO 6400 exposures stacked in Sequator, post-processed using the Photoshop 2018 Camera Raw filter. Nikon D850, Tamron 15-30mm @ 15mm, f2.8.
Milk Way from the Languedoc Hills. Tracking is better than last shot - no trailing but a little more noise.

Still can't find my polarscope but these 20 sec exposures didn't appear to drag so I took 31 lights to get a stack of 10 mins.

Hallo zusammen
ich war wieder mal in der Nacht draussen um die Milchstrasse aufzunehmen. Gleichzeitig habe ich noch einen Timelapse gemacht. Meine Idee ist, ich bin hier noch nicht fertig, unser Dorf mit der Milchstrasse aufzunehmen, obwohl wir eine recht grosse Lichtverschmutzung bei uns haben (Region südlich von Basel).
Nun ist es so, das in unserem Dorf um 0030 Uhr die Strassenbeleuchtung ausgemacht wird und wir somit bei uns wieder etwas Nacht haben.
Für dieses Bild habe ich 16 NEF mit Sequator gestackt und dann in DxO bearbeitet. Jedes Bild wurde bei ISO 1600, f 1.8 und 13 sek belichtet.
Hoffe das Bild gefällt euch.
Gruss Martin
It's so different to look at completely dark sky and see how much more you can see.
Trying new stacking software: Sequator
It works really well, actually! sites.google.com/site/sequatorglobal/ Definitely worth a try if you're using windows and having trouble aligning with photoshop.
I didn't really intend to do this with these images, I was only running a timelapse pointing in this direction because I'd seen some shooting stars in this part of the sky... so the exposures are a bit too long for perfect sharp stars, but I still like it.

Truly, no kind of photography is as unforgiving as astro. I've had my tracker for a year and barely scratched the surface because it's so easy to mess up. One setting off and it's all ruined. So many cloudy nights. So much condensation on my lens. But trial and error leads to honing your skills, and then hey, you get a picture of a nebula 5000 lightyears away. Neat!
Let's get the tech stuff out of the way:
Canon 80D with Canon 70-200 f4L IS (IS turned off)
iOptron SkyGuider Pro
Approx. 50 exposures of 45", f4, ISO 1600

No vignetting frames

The first time I tried to use this new stacking software (sequator), I of course did not read any instructions and had no idea what I was doing... So I didn't tell it to freeze the ground in place*. What I ended up with was this image, with the exposures aligned on the stars, and the motion of the earth emphasized. I probably won't do this intentionally again any time soon.
But I do like how this little accident made an image that really amplifies one of the things I really like about starry sky photos - the visualization of our place in the universe.
*I actually never did, for the other stacked versions, I masked in a non-aligned stack with the exposure adjusted for more foreground detail over the top of something like this
The 27mm equivalent I had on the "big" camera wasn't really wide enough to get the dark part of the sky along with the horizon and the foreground, so the images from it aren't as good as I'd hoped, otherwise. (I'm getting a wider, rectilinear lens for it soon)
I took 11 original photos in the middle night of 7/8-79 and post processed them in Sequator to generate this final picture.
HST 2017-Dec-18 ~4:45am. Unmodified Canon 60D, Rokinon 16mm f/2 lens stop down to f/4, ISO 4000, 64 * 15 sec total exposure, 50% resized and cropped. Processed by Sequator, Fitswork, and Photoshop. The temperature is ~-5 Celsius, with gusts of ~30 mph. The cloud was illuminated by an active volcanic crater on Mauna Loa. A part of the zodiacal light is visible at the left edge of this image. Airglow made the sky look greenish, and of course I couldn't see the tint through my naked eye.
I didn't expect that my portable power bank went dead that quickly during the first two nights I stayed at Hale Pohaku. So I was forced to use short exposure time when I finally had a clear night at the JCMT, on the summit of Mauna Kea. The JCMT couldn't be opened that night because of the strong gust. A membrane has been removed from the telescope so it is more vulnerable to winds, and the max wind speed the telescope can withstand is merely 18mph. I got no data at all from the observing run, but just some pretty (I hope so) pics with my amateur setups.
Hawaii local time 2017-Dec-18 ~5:40am. Unmodified Canon 60D, Rokinon 16mm f/2 stop down to f/4, ISO 4000, 10 * 30 s coadded in Sequator, noise reduction in Fitswork and stretch in Photoshop.
My telescope operator Kevin was driving us down from the summit, since the night was totally hopeless to operate. Kevin noticed the orange light from the volcanic crater on Mauna Loa so we stopped to park the vehicle to a parking lot at an elevation of 3900 m. The gust was so strong that I couldn't even stand firmly. Of course it was very cold too, definitely below freezing point I'd say. After I finished taking the photos, the windscreen had been covered by a layer of frost and Kevin had to manually scrape it off with a brush. What an experience!
So I didn't completely fail. On my desktop screen I could just make out a little green color right where it should be. The bright star just above the green comet is Bellatrix, Orion's right shoulder. There are some great shots on the web taken with telescopes. Spaceweather.com said it was an easy pick with a camera. Didn't seem that easy. It is 54 million miles away. At it's closest approach to Earth. I had planned to take multiple exposures and stack using Sequator but could not see it on the camera screen.
