The Crab Nebula supernova remnant in Taurus. The Chinese, Mayans and others saw It when it blew up in the year 1054. It contains a pulsar (neutron star) at its center.
This was taken with a Seestar S50 Smart Telescope using 30 sec sub-images. It has about an hour of total integration time that finished up just after midnight last night (12:24 A.M., Dec 24, 2025.)

It was not the best night in terms of transparency, so I put a lot of time imaging this object thinking I could get past that with enough sub-images. Unfortunately, 2.5 hrs was still not enough under those conditions.
I couldn’t boost this image the way I wanted since it was still pretty noisy. Plus, my flat, which I have since replaced, was faulty with a green blotch on the mid-right side. I think I’ll re-image this one now that I can better calibrate it with a new flat.
I took some subs in the second week of Dec 2025 and it was sparse data. So, I copied back to the Seestar all data I had on it since Dec of 2024 and restacked and combined it all together. I came out with 12270 seconds or 3.4 hrs worth:
A rainy day project to combine all the data taken with the Seestar S50 that was not parts of any mosaic mode sessions. It seems you can only restack non-mosaic mode sub-images, so I did that and came up with this image below.
Well, here it is, the interstellar comet everyone was so worked up about. I didn’t see it as anything too special. It was small, dim and what I term, “a runt comet.” lol
Anyway, it was conveniently placed in the sky, so I took a look the day after it’s, “closest approach to Earth,” (nearly 180 million miles away.) Yes, it’s not too impressive at this scale. The guys with 10 inch or larger scopes had better luck with this little runt of a comet.
Here’s a collection of images taken of Comet Lemmon (C/2025 A6) in October 2025 through November 2025 . Most were taken with a new ZWO ASI2600MC Air Smart Camera, which I purchased right before Comet Lemmon was at its best. I hooked it to my Astro-Tech AT60EDP at F/5 . Two were taken with my Seestar S50 (third from the bottom and the bottom image.) One was with a Canon T3 and a 180mm F/4.5 Askar Astrograph lens (second from the bottom.)
This was perhaps the best comet since the 2024 apparition of Comet C/2023 A3 (Tsuchinshan-ATLAS) in October of 2024.
Some of the best images I took of Comet Tsuchinshan-ATLAS (C/2023 A3) during its apparition in Sep 2024 through Nov 2024. Cameras used included my Canon T3, a QHY294C and a Seestar S50 and various lenses and my Astro-Tech AT60EDP F/5 telescope.
The Seestar S50 comes with a solar filter and works pretty well imaging the Sun. This was my first try at it.
After waiting a while for the tech to mature, I decided that a Smart Telescope would be fun to play with. So, I got the cheapest one on the market.
ZWO built it originally and they spun off a new company called Seestar to market it. In this case, the unit is the Seestar S50, a 50mm triplet in an all-in-one design including mount, camera, computer and storage.
Here’s the first light images from it:
