It was a little hazy with below average transparency Christmas Eve night 2025, so before it got too bad, I decided to try and take a mosaic of the Double Cluster, instead of a nebula or galaxy as a target. Taken with my Seestar S50 for 48 minutes using 30 sec sub-images.
he 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.
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:
