Deep Sky Stacker

DeepSkyStacker + Lr - my first attempts to stack photos. Photo consisting of 21 photos with exposure parameters 12 mm, f / 2.8, ISO 3200, 5s - OBO tripod + Manfrotto XPRO 3W.
I have calculated that for an observer using a 12mm lens (MFT) and an eye resolution of max 1 "angle (this is for a person with great eyesight and for good eyesight it is 2" angular) - the maximum exposure time for getting the view of unmoving stars is about 4,33 s. Such photos without visible foreground can be snapped and then folded as panels with the foreground not moved into a mosaic.
I wanted to check if (O-MD E-M10 Mark II) M.Zuiko 12-40 mm f / 2.8 could work in the landscape field Astro (with the subject of the foreground on the ground) without a head with guidance (sky with stars as mosaic panels ) - please give me an opinion.
I am thinking of using Star Adventurer or iOptron Skyguider Pro, but since the results of star formation are punctual, does it make sense to use the head leading to the astro landscape with the subject of the foreground on earth?
The blurred glow at the bottom of the photo comes from slowly flowing clouds gently lit by the glare of lights from a city 20 km away (Opoczno).

I spent Sunday night setting up my scope again, aligning it, and tracking the Triangulum Galaxy. The Triangulum Galaxy lies ~2.7 million light years away from Earth and is part of our local group of galaxies. It lies in the constellation Triangulum, from where it gets its name. Charles Messier cataloged it first in 1764. He published his Catalog of Nebulae and Star Clusters in 1771 and listed it as object number 33, hence the name M33.

My Sony a7RIII and adapted Nikkor 500mm f/4 P AI-S were mounted on an ADM vixen rail and secured to the SkyWatcher EQ6-R mount. I polar aligned my mount using SharpCap Pro. The guide scope/camera was attached to the camera's hot shoe. I used PHD2 to autogude during the imaging session. DeepSkyStacker was used to combine all frames, and then I processed the TIFF file in Photoshop. I stretched the 32-bit file and used Gradient XT on the image. I then made it a 16-bit file and continued to stretch the file in levels, then curves. I used the color sampler tool and levels to do my best to help keep colors accurate. I then used my skillset, including some dodging & burning, and relied on Astronomy Tools Action Set and Topaz Denoise to give the image a polished look. I brought it into Lightroom to do final color corrections and add EXIF data.
This is a reprocess of my M42/M43/NGC1977 shot from last Saturday night. I wasn't entirely happy with the original process, so I started over. This shot is a labor of love. All told, I'd estimate 20 hours of work went into producing this image.

Comet Leonard has been a putting on a bit of a show for those in the Northern Hemisphere in recent weeks, but it has now become visible in the Southern Hemisphere. Unfortunately it is fading now, but it is still a nice binocular object low in the west after sunset. This image was taken last night from Brisbane, before the sky was fully dark. The comet is at top left and Venus is below and to the right.

I originally planned to shoot this morning with a 500mm lens. I went through the rigamarole of getting the telescope and all of it's components out so I could track the comet with my camera/lens piggybacked on top. The scope was aligned and tracking. I slewed it to Comet NEOWISE and took a test shot, the tail was just MASSIVE in the dark sky. The 500mm was too long, it was cutting the tail off. Changing the 500mm to the lighter 300mm lens mean that my telescope had to be re balanced. So I turned it off, took off the 500mm, put on the 300mm and reattached the camera/lens on the top rail. I redid the blance on the RA and Dec axes and went through the alignment process again, it was ready to shoot but I'd lost 12 minutes. The previously dark say was already appearing more blue and with less stars. I felt a bit discouraged but went ahead and programmed the intervalometer to shoot 10 second exposures at f/4. I let it run while I observed the comet through the telescope's finder scope. I wound stacking the 90% best of the first (darkest) 15 frames for a total integration time of 2 minutes and 30 seconds of imaging.
The Triangulum Galaxy is part of our local group of nearby galaxies. It is ~only~ 2.7 million light years away from us. It is the third largest after our Milky Way and then Andromeda. The Triangulum Galaxy faces us head on so it is not as bright as Andromeda which shines nearly 8 times as bright. I could not make it out in my telescope, only after a long exposure could I see it on my LCD screen.

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 piggyback my Sony a7RIII and adapted Nikkor 500mm f/4 P Ai-s on a ADM dovetail rail on the top of my optical tube. I used DeepSkyStacker to combine all frames and then processed the TIFF file in Photoshop. I stretched the 32 bit file and used Gradient XT on the image. I then made it a 16 bit file and stretched in level, then curves. I used the color sampler tool and levels to do my best to keep the background space black. I did use layer masks to bring out the color in the galaxy without making the stars look like christmas lights. I then using my skillset and relyed on Astronomy Tools Action Set, and dodging and burning a bit to give the image the finishing touches.

My Sony a7RIII and adapted Nikkor 500mm f/4 P AI-S were mounted on an ADM vixen rail and secured to the SkyWatcher EQ6-R mount. I polar aligned my mount using SharpCap Pro. I struggled with getting guiding going and decided to trust my mount to track accurately. I took 4 121-second exposures and dark, flat, and bias frames. DeepSkyStacker was used to combine all frames, and then I processed the TIFF file in Photoshop. I stretched the 32-bit file using Levels. I then made it a 16-bit file and continued to stretch the file in levels and curves. I used the color sampler tool and levels to do my best to help keep colors accurate. I then used my skillset, including some dodging & burning, and relied on Astronomy Tools Action Set and Topaz Denoise to give the image a polished look. I brought it into Lightroom to do final color corrections and add EXIF data. I did not attempt to account for the comet's movement, and you can see the nucleus is elongated.
This is 11 stacked 10 second exposures taken at ISO 16000. I used Deep Sky Stacker to stack the images and processed in Lightroom 4. I was surprised the camera was able to pick up a bit of the comet's tail. :)
This was the intended target from yesterday but the total time between clouds was shorter.

Perseiden Beobachtung an der Hunte zwischen Oldenburg und Berne. Dies ist eine etwas aufwändigere Nachbearbeitung in der ich 50 Aufnahmen a 15 Sekunden gestackt habe: einmal für den Vordergund ohne Kompensation der Erdrotation, und einmal mit Rotationskompensation für den Himmel per DeepSkyStacker. Anschließend habe ich aus einer Serie von 300 Aufnahmen (aus denen auch die ersten 50 stammen) diejenigen herausgesucht auf denen Perseiden zu sehen waren. Diese habe ich per Ebenenmasken manuell eingefügt.

Perseids observation on the Hunte between Oldenburg and Berne. This is a somewhat more complex post-processing in which I stacked 50 shots of 15 seconds each: once for the foreground without compensation of the earth's rotation, and once with rotation compensation for the sky via DeepSkyStacker. Then I selected those from a series of 300 photos (from which the first 50 were taken) on which Perseids could be seen. I inserted these manually using layer masks.
This nebula is located in the milky way near the Crux. 50 shots at 2 secs each with an aperture of 1.8 and ISO 3200. Individually processed in DxO Photolab 3.2 and saved as TIF files. I then stacked them all in DeepSkyStacker, saved as a single TIF and then converted to jpg before uploading to Flickr. This photo was taken from my backyard during the Covid-19 lockdown.
This is a remnant of a super nova in the constellation Gemini... in 'Castors foot'. I managed to get the image reversed as I was hoping to combine it with the brighter monkey head nebula instead... but alas my camera was upside down and I managed to confuse the star cluster with the nebula :D

This is the same data as previous image processed differently. The previous image took a long time to process because it had dark streaks in the data (walking noise). Reading up on this it was almost certainly the difference in noise of the dark frames with the light frames. This was confusing because the dark frames were made 10 minutes after the light frames. Then it occurred to me that perhaps the camera sensor cooled in those 10 minutes so I decided to remove the first 10 dark frames. This did the trick. Was able to stretch the data a little more and get some more detail.

My mount was polar aligned with SharpCap (what an amazing system for aligning). I then mounted my a7RIII and adapted Nikon 500mm f/4 P Ai-s lens to the top rail of my scope. I used SharpCap to achieve "excellent" polar alignment. I shot ISO 3200, f/5.6 and 75" exposures. I stacked lights/darks/flats/bias frames in deepskystacker. I then processed the TIFF file in photoshop stretching the file, cropping and I used Astronomy Tools Action Set to help bring out details and colors along with Topaz Denoise to help smooth things out.

If you go, be aware that the constant tracking of dishes will cause motion blur; I listened for the motor to get softer, and crossed my fingers between 30 sec shutter clicks.
Lens is the DFA 55mm f/2.8 on the 645Z. This is a composite of a 6-frame foreground image captured at OVRO in 2020 and a recent set of milky way images(60+ frames), captured at Pinecrest Lake last weekend. I am learning new software, so took this opportunity to make this image using Deep Sky Stacker and StarnetGUI star remover. My post processing is intentionally a bit heavy handed and extra bluey, for effect.
Hope you like it.
I imaged the Pleiades about a month ago. I used my 300mm lens. After getting some time on the Dumbbell Nebula, I took off the teleconverter and shot this target again with a longer focal length than I had before. I also used ISO 3200 and f/5.6 to bring out those diffraction spikes, which I think look really cool.

Andromeda (or M31 in the Messier catalogue), is our neighbor galaxy. The galaxy is approximately 2.5 million light years away from us. Andromeda is bigger than our own galaxy, the Milky Way (150.000 - 200.000 light years in diameter, the milky way is approximately 100.000 - 120.000 light years in diameter). Andromeda contains 1.000 billion stars (300 billion stars are contained in the milky way).
a crop of the previous image, i guess this is currently the maximum i can get with my equipment. i hope i can manage to modify my Canon EOS 50D just before Orion disappears until November to give it another try.

Finally got to a low light pollution sky, and the result is lovely. Finding Polaris was hard in the sea of stars that was visible! There's a million of these images out there, but I'm proud this is mine.
Also the first time I tried something other than DeepSkyStacker, and I am delighted: Siril.
Equipment used:
StarAdventurer Pro
Nikon Z6
Samyang 135mm F/2 on FTZ adapter
Exposure info:
32x 30 seconds at ISO5000, F4, plus a bunch of dark, flat and bias frames.
After a long break from doing astrophotography, I decided to spend some time last night and use the new gear I recently got shooting a popular and relatively easy target, The Pleiades. It does appear the lens was slightly off on focus, but whatever. Most people will never pixel-peep it anyways. It all worked great, and it felt good to capture the heavens again.
Equipment:
SkyWatcher EQ6-R
Nikkor 500mm f/4 P AI-S at f/5.6
Sony a7RIII (unmodified)
ZWO 30mm Guide scope
GPCAM2 Mono Camera
Acquisition:
Taos, NM: my front yard - Bortle 3
68 x 121" for 2 hours, 17 min, and 8 sec exposure time.
10 dark frames
15 flats frames
15 bias frames
Guided
Software:
SharpCap
PHD2
DeepSkyStacker
Photoshop
Lightroom
I polar aligned my mount using SharpCap Pro. My Sony a7RIII and adapted Nikkor 500mm f/4 P AI-S were mounted on an ADM vixen rail and secured to the SkyWatcher EQ6-R mount. The guide scope/camera was attached to the camera's hot shoe. I used PHD2 to autogude during the imaging session. DeepSkyStacker was used to combine all frames, and then I processed the TIFF file in Photoshop. I stretched the 32-bit file and used Gradient XT on the image. I then made it a 16-bit file and stretched it in levels, then curves. I used the color sampler tool and levels to do my best to help keep colors accurate. I then used my skillset and relied on Astronomy Tools Action Set and Topaz Denoise and Sharpening to give the image a polished look. I brought it into Lightroom to do final color corrections and add EXIF data.
Due to bad weather conditions, I wasn't able to capture other pics of the comet until 27/10.... and this is my best shot.
Additional Notes:
- the star at the center is
Beta Ophiuchi (Cebalrai)
- the star on the left is Gamma Ophiuchi
- the little stars close to each other on the top-right are known as the "Summer Beehive Cluster" (IC 4665)

La Nebulosa Grotta (SH2-155) è una nebulosa ad emissione visibile nella costellazione del Cefeo. Si tratta di un oggetto molto debole visibile solo nelle foto a lunga esposizione e si presenta come un insieme di parti brillanti, le emissioni HII visibili in rosso, e nebulose oscure. Il campo stellare in cui è immersa è molto ricco e dona a questa regione del cielo un fascino unico.
Le riprese sono state effettuate la scorsa estate dal monte Pollino.
ENGLISH
The Cave Nebula (SH2-155) is a diffuse nebula in the constellation Cepheus, within a larger nebula complex containing emission, reflection, and dark nebulosity.
The star field in which it is immersed is very rich and gives this region of the sky a unique charm.
Filming was done last summer from Mount Pollino.
