The open cluster NGC 2158 is one of those things that made me do a “double take” when I got back into astrophotography several years ago. Of course I knew about the open cluster Messier 35 (M35), but when I looked at my first DSLR photo of M35 and spotted that hazy little ball nearby, I thought I found something new, a comet perhaps….not the case.
NGC 2158 is located in the constellation Gemini, southwest of M35. While it looks like they are close together, NGC 2158 is actually around 9,000 light-years behind M35 (11,000 light-years from Earth). It has an apparent magnitude of 8.6.
Tech Specs: The close-up image is composed of 14 x 60 second images at ISO 3,200 with 5 x 15 second darks and 5 x 1/4000 second bias frames using a Meade LX90 12” telescope and Canon 6D camera mounted on a Celestron CGEM-DX mount. Imaging was done on February 26, 2017 from Weatherly, Pennsylvania. The wide-field inset view was taken in 2014 using a Canon 6D and 400mm lens.

Comet C/2020 F3 (NEOWISE) imaged at around 01:41CEST on 19 July 2020 from the beach at Wassenaar in The Netherlands.
The weather was unhelpful, with clouds drifting through, and this is the best set I could get in the brief time before it was completely socked in. At least it shows the ion tail nicely, extending to 15º or more from the nucleus.
Nikon D7000 + 85mm lens at f/2, 40 x 3 sec exposures unguided at ISO 800. Aligned and combined in DeepSkyStacker, then post-processed in LightRoom.
The small purple squares around the brighter stars are probably linked to saturation in the CMOS detector, enhanced in this processing. The whole image is more "impressionistic" than accurate, colour balance included, but hey, we've also seen more than enough pristine Comet NEOWISE pictures, right? :-)

Chinese astronomers in 1054 recorded a new 'star'. This new star was visible during the daytime for almost a month.
What they were actually witnessing was a supernova, the death of a star.
This particular star was about 6,500 light years away. They didn't know it at the time but, they were witnessing something that actually happened around 5,450 BC.
It's believed that the Crab Nebula is the remnants of that supernova.
M1 is six light years across!
It was first discovered in 1731 by John Bevis. M1 is what inspired Charles Messier to later start his now famous Messier catalogue. After he thought he'd found Halley's comet and realised it wasn't, he decided to make a list of things that weren't comets, and so therefore, not worth observing. Now, every astronomer and astrophotographer are fascinated by them.

The Fossil Footprint Nebula.
Discovered in 1790 by William Herschel NGC 1491 can be found in the constellation of Perseus at a distance of approximately 11,000 light years from us.
Known as a HII region. This type of nebulae is caused by ultraviolet radiation from the hot young stars being born within ionizing the surrounding nebula, which cause it to glow in visible light allowing us to see it.

Astrophotography is and has been my thing for a few years now. My main focus has always been the stars. Im happy to share the second of my two milky way shots in the Dolomites with you.
I reedited this one with Pixinsight which i have started to learn the basics of.
Edit: If you like my work and want to see more check out my Instagram @photodiction
Gear:
* Nikon D850
* Nikkor AF-S 50mm 1.8 ED
* IOptron Skytracker Pro
Settings:
* Sky: 10x f4 60s ISO3200
* Foreground: 5x f1.8 60s ISO6400

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.
Finally! DeepSkyStacker 64 is here and it is Open source!

The thin, dark disk of dust around the galaxy shows up very nicely.
33 x 1-minute at ISO 6400 (taken 14 April 2020) and 8 x 3-minutes at ISO 1600 (taken 8 May 2018). Modified EOS 600D & Revelation 12" Newtonian f/4 reflector telescope.
Frames registered and stacked in DeepSkyStacker software; curves adjusted in Canon Photo Professional; noise reduction in CyberLink PhotoDirector.
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.
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.
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!

This is the Great Orion Nebula which spans 14 light years across. This Nebula is a nursery for stars that are only 1 million years old. This makes them practically infants when you compare them to our own Sun, with an age of 5 billion years. The Nebula sits approximately 1,500 light years away from us.

Located 6,400 light years away in the constellation of Orion, the Monkey Head is an emission nebula and home to the open star cluster NGC 2175.
The nebula acts as a womb for new stars to be born. Those new stars then radiate such immense energy that blasts in to the surrounding gas and dust that makes up the nebula. This has the effect of not only clearing away the surrounding nebula from the newly born star but, causes the gas and dust in other areas to be pushed together. When enough of this material is pushed together it allows gravity to take hold and pull more and more of it in. When enough of it is pulled together there's a good chance another star will be born.

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 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.

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 :)
The Rosette Nebula in Monoceros, aka Caldwell 49 or NGC 2237. The open cluster in the middle is affectionately known as NGC 2244, or more formally Caldwell 50 :)
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 :)
