After spending some time on M5 I thought it would be fun to try some widefield Milkyway shots. I had to rebalance and go through the alignment procedure for my scope. I switched the 500mm for a more modest 35mm f/1.4 lens. I decided to shoot it at f/2.8 so it wasn't just wide open and trust my mount that had been polar aligned with SharpCap to do it's thing. I wanted a bright star to help define the area of the sky, so I chose Altair which can be seen in the middle right of this frame and let the gear do it's thing.

The Orion Nebula (also known as Messier 42, M42, or NGC 1976) is a diffuse nebula situated in the Milky Way, being south of Orion's Belt in the constellation of Orion.[b] It is one of the brightest nebulae, and is visible to the naked eye in the night sky. M42 is located at a distance of 1,344 ± 20 light years and is the closest region of massive star formation to Earth. The M42 nebula is estimated to be 24 light years across. It has a mass of about 2000 times the mass of the Sun. Older texts frequently refer to the Orion Nebula as the Great Nebula in Orion or the Great Orion Nebula.
The Orion Nebula is one of the most scrutinized and photographed objects in the night sky, and is among the most intensely studied celestial features. The nebula has revealed much about the process of how stars and planetary systems are formed from collapsing clouds of gas and dust. Astronomers have directly observed protoplanetary disks, brown dwarfs, intense and turbulent motions of the gas, and the photo-ionizing effects of massive nearby stars in the nebula.

Barnard 150 is a dark nebula, also known as the Seahorse Nebula, located in the constellation Cepheus. It is about 1,200 light years from Earth. The nebula is so thick that it absorbs all light from stars behind it, making it stand out against the background of the Milky Way.
The nebula is shaped like a seahorse and is visible in silhouette against a background of stars. It has three dense dust cores, which are star formation regions. These cores were cataloged by Lynds and named LDN 1082 A, B, and C. This is almost 6.5 hours of collected light.

Helix Nebula
The Helix Nebula, also known as The Helix, NGC 7293, is a large planetary nebula (PN) located in the constellation Aquarius. Discovered by Karl Ludwig Harding, probably before 1824, this object is one of the closest to the Earth of all the bright planetary nebulae.[5] The estimated distance is about 215 parsecs (700 light-years). It is similar in appearance to the Cat's Eye Nebula and the Ring Nebula, whose size, age, and physical characteristics are similar to the Dumbbell Nebula, varying only in its relative proximity and the appearance from the equatorial viewing angle.[6] The Helix Nebula has sometimes been referred to as the "Eye of God" in pop culture,[7] as well as the "Eye of Sauron".[8][9]

M27, The Dumbbell Nebula was the first planetary nebula discovered by Charles Messier in 1764. It is located 1360 light years away in the constellation of Vulpecula and is about 2.8 light years in diameter. Our own sun will produce a planetary nebula like this in about 5 billion years time when the hydrogen and helium depletes and it collapses into a white dwarf.

Although it looked clear when I was taking the photos, there were actually some high, quick moving, thin clouds which long exposures unveiled.
It'd been awhile since I'd been astrophotographing - felt great to be out under the stars and a smokeless sky. Fall is a excellent time for widefield astrophotography in the western US - there's a decent amount of astronomic dark, plenty of clear nights, temperatures aren't too cold, and quite a few interesting widefield subjects are available.
My goal with this small mosaic (only 2 panels) was to capture both the Fireworks Galaxy (NGC 6946, tiny here, bottom left) and the Elephant Trunk Nebula (IC 1396) in the same extent, with all of the interesting nebulosity in between, most notably the dark nebula Barnard 150 (AKA the Seahorse Nebula) in the lower left, one of my favs.
Surprisingly, I didn't detect much of the red emission Flying Bat Nebula (Sh2-129, center), part of which actually appears bluish (?, at first I was excited that I might have detected the Giant Squid Nebula (OU4), but nope, the blue is not in the right place). Previously I had captured Sh2-129, albeit faintly, with this same set up in the same location.
Part of the reason for this is that I stopped my Samyang 135mm down a half stop to f 2.4 (which I usually shoot wide open at f 2), not to tighten up stars, but to flatten out the heavy vignetting a tad. It did make a difference, but I did also notice that the Elephant Trunk Nebula didn't show up as strongly as expected based on my previous imaging of it. I'm still undecided whether I'll stay with f2 or move to f2.4, might depend on the subject.
There is a decent amount of what appears to be blue reflection nebulosity around star HD 198793 in the upper left quadrant; looking at widefield images of others, I can also see this faintly, but I haven't been able to find any closer images of it yet and it isn't cataloged in my astronomy app (SkySafari 6 Plus). It's possibly a processing artifact although it doesn't appear to be one.
Acquisition details: Fujifilm X-T10; Samyang 135mm f/2.0 ED UMC @ f2.4, ISO 1600; tracking with iOptron SkyTracker Pro; two panel mosaic - 42 x 60 sec and 44 x 60 sec; stacking with DeepSkyStacker; editing and mosaicking with Astro Pixel Processor; and curves adjustment/star reduction/editing with GIMP; taken on Aug. 31, 2021 under Bortle 3/4 skies.
I have photographed the Triangulum Galaxy over the years, but this is the first time I have attempted it with my Meade 12″ telescope. The galaxy extends further than what is shown in this image. I’ll attempt a mosaic image as I add more data to this view. Technical details: Total exposure time was 26 minutes using 20 second subs at ISO 6400. Images were stacked using DeepSkyStacker and adjusted using the software packages ImagesPlus, Adobe Lightroom and Corel PaintshopPro X5.

I'm somewhat, not completely happy, with this one. Pulling out the dark nebulae and dust among all of the stars, with a not-completely-flat field and a light pollution gradient from shooting fairly low, was tricky.
I plan to shoot this extent again 1) when it is higher in the sky later this year, 2) possibly with 90 sec subs instead of 60 sec (although tracking was spot on with a 90% keeper rate at 60 sec), and 3) I might experiment with PixInsight to better emphasize the dark nebulae while deemphasizing the stars.
April 26 update: Cropped
Aug 8 update: Reprocessed using raw instead of out-of-camera jpeg. Definitely some advantages to using raw.
Aug 26 update: Reimaged when closer to zenith, 54 x 60 sec this time, the two versions are extremely similar (so I just replaced the older with this one) although this one has the edge in that dust cloud representation is more accurate. Processing with this cleaner data was much easier, and involved much less manipulation.
Sept 13 update: Reprocessed with Astro Pixel Processor. I like the colors a bit better, and after several reprocesses I've decided to leave the dust cloulds fairly dim, since I don't like how it turns out when I stretch too far. This is just a tricky extent - the dust is so dim. Maybe I'm finally going to leave it alone. I'm excited to tackle the Dark Shark and Wolf's Cave nebulae widefield again, but am going to reshoot since I don't have raw files.
Oct. update: Alright, I wasn't done. I couldn't help but give it another try. The nebulosity is now a bit brighter, the color of the iris is bluer, and the stars slightly more reduced. I also upped the contrast and saturation of the Ghost Nebula. Maybe I'm done now.
April 2020 edit: Still wasn't done. I upped the brightness and contrast of the dark nebulae a bit more.
NGC 4449, also known as Caldwell 21, is an irregular Magellanic type galaxy in the constellation Canes Venatici, being located about 13 million light-years away. It is part of the M94 Group or Canes Venatici I Group that is relatively close to the Local Group hosting our Milky Way galaxy. This galaxy is similar in nature to the Milky Way's satellite galaxy, the Large Magellanic Cloud (LMC), though it is not as bright nor as large. NGC 4449 has a general bar shape, also characteristic of the LMC, with scattered young blue star clusters.

I know I've not long since imaged this but, I'd setup in hope of the clouds clearing over my local observatory.
Just as I was about to pack everything away, we got a gap in the clouds. M27 was ideally placed right in the gap, so I managed to get 30 exposures of 2 minutes each and some calibration frames with them.

lots and lots of cleanup in photoshop CS - to fix internal reflections and ccd bleed.
final tweaks and color balance in lightroom 2
comments: color subexposures were way too long, resulting in a ridiculous amount of star halo and ccd bleed on the 3 largest stars. this took a lot of work in photoshop to undo, and it's still obvious that there was a big problem there. this was especially bad in the blue channel, hence the purple cast around the big stars.

Acquisition time: JD2456984.32694 (22.11.2014 23:50:47 MSK).
Image orientation: something like straight.
Equipment:
Canon EF 70-200 f/4L USM backed by Astronomik CLS-CCD clip-in filter on Canon 60D (unmodded) riding #Polarie.
Aperture (effective) 40 mm
Focal length 200 mm
Tv = 120 seconds (risky business, trailing is apparent)
Av = f/5
ISO 3200 (overdone, perhaps)
Exposures: 40 (plus 22 dark frames, plus master bias from the library plus 100 flat-field images)
Processing:
Images were converted into Adobe .DNG with Abode converter and stacked in DSS.
Final adjustment was made in Photoshop.
I collected as many images as I could in one night to create this image of the handsome California Nebula in the constellation Perseus.
The final image includes 90 x 5 minutes through this ultra-portable astrophotography rig featuring the mighty William Optics RedCat 51.
While the nights are now very cold, they are also much longer and allow me to start shooting a LOT earlier

Orion nebula photographed with 2.8/300 mm lens.
Yes, that works quite well!
0.8 sec exposure time, aperture 2.8, ISO 6400, approx. 5x digital magnification.
29 best photos out of 100 selected and calculated with DeepSkyStacker, with 15 darkframes (calculation of image noise) and 15 biasframes (calculation of transmission noise)
Without tracking!
Tripod low, no wind.
A few pictures taken with Nikon D7500 & Sigma 100-400 lens at 400mm, mounted on Skywatcher Staradventurer, stacked using Deepskystacker.
This clearly shows that the comet is moving fast!!
Unfortunately the clouds rolled in after only 10x 20s subs. Would have liked an awful lot more to bring out the detail in M81. Reprocessed data using 20 flats, 20 bias and 10 darks.

I took some time to collect some additional data on the galaxies Messier 81 and Messier 82 (M81 and M82) in the constellation Ursa Major on the evening of February 28, 2016. I used my wide-field setup which includes my Canon 6D and Canon 400mm lens mounted on an iOptron ZEQ25 mount. I collected 28-minutes of data using 60-second sub frames at ISO 3200. I also took the time to clip and process some of the background galaxies in my large 3 x 5 degree image, you can view them on my blog at: www.leisurelyscientist.com/?p=1592
Among the astrophotographs I made, this is, at the moment, the one with the longest total exposure time, totaling 19 hours and 35 minutes (captured in four nights).
"The beautiful spiral galaxy Messier 83 is located in the constellation Hydra and is also known as NGC 5236 and as the Southern Pinwheel galaxy. Its distance is about 15 million light-years, being about twice as small as the Milky Way". Source: eso.org

A few things came together for this one...
After a lot of experimenting, I can say I'm finally happy with some of the results. And aside from all the technique, it took me quite a bit of patience to catch a long exposure with a truck on the road making colorful light trails in front of mountainous scenery without getting the shot ruined with oncoming headlights. Then up top, I got the stars including Rigel and a few constellations to appear as points of light. Best of all, it looks good large!
This image, coming from several exposures taken in sequence, was captured on Loveland Pass, near the Arapahoe Basin Ski Area and Keystone, Colorado. Oh and those glowing clouds at the top of the mountains... That glow comes all the way from Denver - some 50 miles away!
On the tech side, I used Deep Sky Stacker to reduce noise in the stars by combining 10 8 second exposures (ISO 3200, f/3.2). Then I used a homemade approach to extrapolate the settings needed for a long exposure of the foreground. It allowed me to test in 8 seconds and shoot something cool in 8 minutes (ISO 200, f/4)... sweet!! Oh yea, and I figured out how to (finally) use my live view in the dark for precision focus. On that I'll have to say when I first saw this mostly focused 8 minute exposure taken at ISO 200, I smiled really wide! So after combining the short frames in Deep Sky Stacker, I just blended the results with the foreground in PS.
