I decided to do a little experiment last night, taking a shot of the North American nebula part of the milky way without a tracker or a drive of any sort - i.e. just with the camera on a normal photo tripod.
I used my Nikon Z50, Nikkor 85mm F1.8 and just aimed it whilst on my normal photo tripod.
I set the interval timer to take 4s exposures every 5 seconds and left it running. I turned it off after it had done 45 exposures... no particular reason, I jus thought that was enough for this experiment.
I stacked the raw images in Sequator and processed the final result in Lightroom.
I have to say, I am quite surprised at how well it came out considering I am right across the road from a bright LED street light!
Conjugation of Pluto,Jupiter, Saturn and Mars against the backdrop of Sagittarius constellation. Mercury and Neptune were still in Aquarius constellation at this time. Taken around 3:45am on 5 April 2020. 50 exposures of 8 seconds at F/3.5 and 18mm, ISO 160
5 x 13 sec. f/1.8, ISO 1600 subs, taken with an EOS 5D MkIII and Sigma 35mm f/1.4 on a static tripod and stacked in Sequator software.
The Milky Way rising pre-dawn on March 1, 2022. You can see the glow from Venus about to rise above the horizon. This image is made from stacking 10, 15 second images in Sequator, Rokinon 14mm, f2.8, ISI 8000, Nikon D810.

Went out over the peak of the Lyrids Meteors, and saw a few, but no major one's caught on camera unfortunately. So i made this star trail instead from the images I took that (early) morning.

C/2024 A3 Comet could not be seen with the naked eye or binoculars in the city, but it was visible with a 5-second exposure. So I decided to continuously release the shutter and process the image later. 5 seconds is the exposure limit at the 70mm focal length. The sequator works like a software equatorial mount, superimposing multiple images. By superimposing the images, the sequator was able to clearly reveal stars and comet tails that had been obscured by noise.
This was an alternate stack of the same photos using Sequator vs the previous using DeepSkyStacker. I like the results out of Sequator a bit better and the ease of use.

A revisit of the July 17th data but this time using the RAW format (known as file type .DNG) from my Pentax K-50 with the 85mm f/1.4 Samyang lens. Fixed tripod. Processed in Sequator, which not only works faster than Maxim DL but also, esp. with DNGs, works better. Later I will re-process this with DARKs and Flats. The two trails (dust and ion) extend over 8 degrees according to my calculations.
The Milky Way rises over the Hite Crossing bridge on the Colorado River and Glenn Canyon.
This photo was 3 years in the planning. And then an opportunity opened up: a clear sky, before the moon comes up, mid-week when we'd have the darkness to ourselves to work.
As soon as the sun set, the bridge started to groan from heat shrinkage and it kept making noise all night. The darkness of Glenn Canyon is among the darkest on earth, with no habitation for 100+ miles in any direction.

Second attempt - wider field this time. i feel the last image, having some foregound, gives a better composition / context than this one.

Now, something I've been wanting to photograph for a long time. This is my first attempt ever. The constellation Orion with the bright Orion Nebula, the dark Horsehead Nebula (IC 434), Barnard's Loop, and the Flame Nebula (NGC 2024). All attempted from my backyard, with moderate light pollution.

All comments and advice, as well as criticism, are welcome.
I did a 39 min stack (all 30 secs exposures) of M88 and M91 last night to see if I was going to be able to get a reasonable result on this pair of galaxies with my 500mm and 1.4x converter. I think they will be quite tricky for me. They disappear behind my house before I can get a lot of exposures on them - the front of the house will be too light to get them (I think) because of the street lights. If I get chance, I'll try again though (forecast is not good though for the next few days).

I don't use my D5300 that much, so I thought I would give it a run out on my 6" SCT tonight.

This is a photo of the Carina nebula using a Canon 500d (unmodified). My camera settings for this is: ISO 1600, 6 seconds, F5.6, manual mode and 250mm. The programs I used to edit were sequator (1200 photos stacked), starnet++ and photoshop.
COMET LEONARD: WIDE ANGLE (2021-12-03)
Shot between 09:55 and 13:27 UTC, in Pinnacles National Park, California, USA. Me and my partner in crime climbed up to the Bear Gulch Reservoir, scouted a nice and secluded spot before the sunset and returned back in the night (it wasn't the best idea to go through those places in the dark, one needs to be very and very cautious in doing so!). I decided to go lightweight and not take my tracker with me that night, as the weather forecast was looking rather iffy (it turned out to be way better closer to the time when the comet started rising above the horizon, but hey, quite often these predictions resemble gambling, lol). While my Nikon D610 and 15mm f/2.4 lens were shooting generic wide angle timelapses, for the comet I went with my ZWO ASI533MC and Rokinon 16mm f/2 lens. It was yet another gamble, as I wasn't sure how impressive it will look at a such a short focal length (spoiler - not much, but better than nothing!). We were able to find and observe it using binoculars, which was cool, our first encounter with the comet! Luckily, framing was correct, which is why there is a segment before the appearance of the comet (I've started shooting way ahead of time, to see how the setup behaves). What I do like in the timelapse - beside the movement of stars across the sky, we can also can notice the movement of the comet across the star field (fun fact - the bright "star" right above the comet is actually the globular cluster M3)!

Sequator in timelapse mode (29 frames per stack, with foreground masking)
RawTherapee for post-processing tweaks
Luminance HDR for tone-mapping (helped bringing up the foreground)
Enfuse to merge the previous 2 results
Custom script for preliminary extraction of the comet zoom-in view
Siril to align the results above
RawTherapee for post-processing tweaks
ImageMagick for overlaying the comet zoom-in
ffmpeg to create the timelapse video

MKVToolNix for adding soundtrack
FAQ:
- Where are the planes, satellites and meteors?
- Removed by the stacking, nice side-effect, I hate the airplanes flying in my frames!
- Why foreground is so static? Was it masked in?
- Again stacking is the answer here, completely nullified the movement caused by the wind
- What are those ghostly things moving across the sky at the start of the video?
- Clouds. Yet again stacking had an impact here, creating a strong blurring effect
- Where is the color, beside the green coma of the comet?
- It has been mostly killed off in the post-processing, to hide all the ugly artifacts. Not happy about it, but didn't have much choice (and skill)
- What is the soundtrack?

The Markarian Chain is a strip of galaxies that forms part of the Virgo Cluster. It is called a "chain" because, observed from Earth, the cluster has along a vaguely curved line. His name refers to the Armenian astrophysicist "B. E. Markarian", who discovered their common motion in the early 1960s The cluster includes, among other galaxies, M84 (NGC 4374), M86 (NGC 4406), NGC 4477, NGC 4473, NGC 4461, NGC 4458, NGC 4438 and NGC 4435..
At least seven galaxies in the Markarian Range move seemingly consistently, although others appear to overlap entirely randomly.

On the last night of summer and the first night of fall, me and my friend hit the road and went to a Bortle 3 location to try and catch the predicted outburst of the Aurigid meteor shower. It wasn't anything as impressive as Perseid meteor shower, but still enjoyable and special. Here is what we caught with the camera looking to the left from the radiant!

My best Milky Way photography to date. I shoot it from dark sky trip, in bortle 4 sky. This photo was stacked in sequator (DSS didn't work) out of 194 30 second exposures with 50 darks and 50 flats. It has been taken with Nikon D3500 aps-c sensor DSLR at ISO6400 and 18-55mm f3,5-5,6 lens at 18mm f5. Total exposure time is 1 hour 37 minutes. I used super pixel mode to merge 4 pixels to one super pixel, so the resolution is only 6 mpx. It took me about two hours to process this image in Photoshop CC2020 and mobile app Snapseed.
