LDN 673 (upper right quadrant) is one of those dark nebula that I often stopped to admire when surfing astroimages. I was excited to find that I could capture some of its structure at 135mm, and that it would fit nicely in the same 135mm extent with the more frequently imaged Barnard's E. This shot has been planned for awhile but took me awhile to get to.
Acquisition details: Fujifilm X-T10; Samyang 135mm f/2.0 ED UMC @ f2.0, ISO 1600; tracking with iOptron SkyTracker Pro; 36 x 60 sec; stacking with DeepSkyStacker; editing with Astro Pixel Processor; and curves adjustment/star reduction/editing with GIMP; taken on Sept. 2, 2021 under Bortle 3/4 skies.
I shot this area with this exact framing last December, but wanted to improve my image. This time my focus was better (I didn't have a Bahtinov mask then), I shot and processed raw (jpeg last time), and I used Astro Pixel Processor tools for processing.
The only thing that wasn't better this time around was my tracking - I only used 50% of my subs, many of which still had slightly trailed stars; I think my balance was off. I would have liked more integration time, but still got a result I'm happy with using only 35 minutes of data.
Fujifilm X-T10, Samyang 135mm f/2.0 ED UMC @ f2.0, ISO 1600, 35 x 60 sec, tracking with iOptron SkyTracker Pro, stacking with DeepSkyStacker, editing with Astro Pixel Processor and GIMP, taken on Oct. 6, 2019 under Bortle 3/4 skies.
Jan 7 2020 edit: A very slight re-edit - I monkeyed with the original stack a bit less this time - I like the Horsehead Nebula better in this version.
This is a stack of 30 exposures of 60s each of the Cygnus constellation (plus 8 dark-frames). The camera (Sony ILCE7) and the prime lens (Sonnar T* FE 55mm F1.8 ZA) have been attached to a "Star Adventurer"-mount in order to compensate for earth rotation, while shooting at F2.8/ISO 1600. Stacking has been done with DeepSkyStacker, and final editing with Photoshop CC 2015.
My first go at the Andromeda Galaxy (M31) using the TAIR-3S (300 mm f/4.5) and unmodified Samsung NX30. 44x 30 s (+20 dark frames, 20 bias frames) @ ISO 3200. Tracking using clockwork-driven barndoor mount. Focusing with Bahtinov mask. Stacking with DeepSkyStacker using Superpixel Debayering. Post-processing using Fitswork and Aurora HDR 2018.
The image was acquired from Byala, Bulgaria at the Black Sea coast while the galaxy stood nicely over the ocean on a clear, moonless night, minimising background sky brightness. No optical filters.
EDIT: I wasn't satisfied with the previous version, particularly the strong red chromatic aberrations around the stars. I finally found a way to reasonably correct that using Fitswork. I additionally used Fitswork for de-vignetting and noise reduction (wavelet filter), as well as some subtle color balance corrections.

Note that I've cropped the result quite extensively, as I'd framed the galaxy very differently in the 2020 and 2018 exposures, so the edges were very uneven.
Taken with a Sigma AF 70-300mm f/4-5.6 APO DG at 200mm and f/5, Canon T3i DSLR, and Celestron Advanced VX mount. Consists of 35 light and 35 dark frames, each a 90-second exposure at ISO 800, and 21 flat frames. Captured with BackyardEOS, stacked in DeepSkyStacker, and processed in Photoshop.
Data for this was captured at the end of an imaging session back in September and has been hiding on my hard drive ever since!

My mount was polar aligned with SharpCap (what an amazing system for aligning). I'm not comfortable using my SCT as my lens yet. My solution is to piggy back my Sony a7RIII and adapted Nikon 500mm f/4 on a ADM dovetail rail on the top of my optical tube. I had to throw away about 5 frames due to satellites passing through or near my targets. This was low on the horizon and when I came out to end my imaging session I found my guidescope not being able to guide and had to delete my last 3 frames becasue the images were not sharp. It was a fun learning experience, looking forward to trying again when this target is higher in the sky.

My mount was polar aligned with SharpCap (what an amazing system for aligning). I'm not comfortable using my SCT as my lens yet. My solution is to piggy back my Sony a7RIII and adapted Nikon 500mm f/4 on a ADM dovetail rail on the top of my optical tube. I'm still new to autoguiding. I got some great detail of a galaxy with 3:30 second light frames. For this I stopped down the aperture to get diffraction spikes on the brighter stars and exposed my lights for 4 minutes. I used DeepSkyStacker to combine all frames and then processed the TIFF file in Photoshop using my skill set and relying on the famous Astronomy Tools Action Set.

Description:
This large, pretty and bright open cluster of stars - which happens to lie in our line of sight in front of one of the bright and star-dense arms of our Milky Way galaxy - is a favourite observational target of northern hemisphere astronomers on summer evenings.
From Wikipedia:
"The Wild Duck Cluster is one of the richest and most compact of the known open clusters, containing about 2900 stars. Its age has been estimated to about 250 million years. Its name derives from the brighter stars forming a triangle which could resemble a flying flock of ducks (or, from other angles, one swimming duck)."

NGC 7000 and IC 5070
The "Pelican Nebula" (IC 5070) can be seen to the right of the "Florida" portion of "America."
80 30-second frames at ISO 1600 and f/4 using a Pentax KP with the Astrotracer feature enabled and the 100mm f/2.8 SMC Pentax-M lens. The images were combined with dark and flat frames in DeepSkyStacker, then processed in CS5, noise reduction with Topaz and further enhancement in Luminar Neo.
This was done in suburban (Bortle 7) light-polluted skies with a nearby rising 98% Moon.
My first reasonably successful photographic meteor hunt! Took a nice spot at the beach, set up the camera and enjoyed the Perseid meteor show. 4 of them also ended up visible in the 89x 30s frames acquired using the Samsung NX30 with the 16 mm f/2.4 wide angle lens (stopped down to f/3.2 to reduce distortion at the edges). ISO setting was 1600. The camera was mounted on a clockwork barndoor tracker. Post-processing included stacking the 60 best frames for the starfield background in DeepSkyStacker, as well as 4 consecutive images each with manual alignment in Photoshop for the sea and tree foreground. Finally the correctly aligned meteors were masked and mounted back into the image.
Acquired on 2021-08-13.

Barnard’s Merope Nebula (or IC 349) is located directly adjacent to the star Merope, often this area is heavily exposed burying this tiny object in the bright majesty of the Pleiades. It is listed as a 13th magnitude (visual brightness) nebula and is very close to Merope (about 0.06 light years). Merope is providing the dramatic lighting effects that you can see in the APOD image listed below.
Tech Specs: This image is composed of 32 x 15 second images at ISO 3200 with five dark and five bias frames. Meade LX90 12” telescope, Celestron CGEM-DX and Canon 6D camera at prime focus. DSS and ImagesPlus for processing. Imaging was done on November 4, 2016 from Weatherly, Pennsylvania.

First attempt at stacking images using the software SIRIL. There's a a bit of a learning curve associated with it, but initial results show a significant improvement over Deepskystacker.
I've had more opportunities to image in the last few weeks than I had for the previous 11 months, or so it seems :)

Another collab with Dave Williams, this time with him providing the Ha and Olll. Added 30% to red and blue respectively with this result, which I have to say I'm quite pleased with :) Better than the last effort I think, as the RGB was better, courtesy of my new go-faster kit :)

The Owl Cluster (NGC 457) in the center and NGC 436 in the upper left. Both are open star clusters in Cassiopiea. An unguided image taken last night over Monticello, NY through a Canon 400mm f/5.6 L lens using a Canon 7D MKII dslr camera on a Celestron AVX mount. Thirty 30 second images, eight dark frames, and fifteen bias frames were stacked using DeepSkyStacker, then enhanced with Adobe Lightroom and Photoshop Elements.
Messier 41 (also known as M41 or NGC 2287) is an open cluster in the constellation Canis Major, sometimes referred to as The Little Beehive Cluster. The cluster covers an area about the size of the full Moon. It contains about 100 stars, including several red giants the brightest of which has spectral type K3, apparent magnitude 6.3 and is near the center, and some white dwarfs.

M15 Globular star cluster.
First discovered in 1746 by an Italian named Jean-Dominique Maraldi. It's approximately 33,600 light years away in the constellation of Pegasus. M15 is one of the densest clusters yet discovered with many very hot blue stars and many of the cooler orange stars becoming more concentrated towards the core.
It was the first of only four globular clusters found to be hosting a planetary nebula. The one in M56 is named Pease 1, after it's discoverer Francis G. Pease in 1928.
It's also thought to contain a black hole at it's core, estimated to be 4,000 times the mass of our Sun.
I also had a little play with the 3D module in StarTools. It looks great using the cross eyed method, but when I save it then try loading to Facebook, it doesn't come out very well sadly.
Took the image with a Skywatcher 8" quattro and a Canon 1100D. Along with some other bits n bobs and lots of images stacked together. Processed everything together with DeepSkyStacker & StarTools.
Mars passing through M44 the Beehive star cluster on June 2nd. Through smoke and light pollution has a lucky chance and just enough time for some quick images as clouds cleared and a a large area of clouds just arriving for the weekend were approached.
