Feb 22 & 23, 2026 Imaging Sessions – Seestar S30 Pro

Feb 22nd, 2026 was a pretty decent night, but I was a little too worn down to travel , so I stayed in the city and tried some nebula and star cluster shots to see how well this new camera on the S30 Pro behaves with clear skies, but heavy light pollution.

To start things off, I did a quickie solar system session and got the moon.  The results are above.   The Seestar S30 Pro’s Image scale is not quite there for moon shots, but that’s why I have the Seestar S50, which works great on that target.

After the moon, I picked the California Nebula as my first DSO target of the night.  It did great on that one.  Afterwards, I tried it on some star clusters.  I shot M44 and M67 in Cancer. Then, M35 in Gemini.   I haven’t gotten around to processing all of the clusters, yet, though.   I’ll add the others once I have them done.

The images below were taken the following night, Feb 23rd, 2026.  It was an even better night than the one before, with max transparency.   I had to try M42 again with the skies this clear!  I used the built-in nebula filter for 30 minutes worth first, then switched to the IR/UV cut (clear) filter and gathered another 45 minutes.  So, a total of an hour and 15 minutes.

I created two versions of M42 – the first being my try at taking the raw stack generated by stacking the two sets of images taken with the different filters and stretching/color balancing it,  Then, the Seestar S30 Pro’s try at stretching it and cleaning it up with it’s AI Denoise tool.  That output was used to generate the base image.  Color was added from my first image, however, since the Seestar had too much LP to deal with to get the color right.


My next subject was the Rosette Nebula.   135 x 20 sec or 45 minutes of data.  I created a starless version to enhance the nebula more and merged it with the stars for the first image.  The second image below is the enhanced starless image itself.

All in all, it was two pretty good nights with some decent images to show for it.  🙂

Seestar S30 Pro – Feb 16, 2026

On Feb 16th, I went to a darker site with a Bortle rating of about 5/6.  It borders on Bortle 4 in the south-southwest.  I got the comet again, M45 and some more tests with the Milky Way mode camera, as the Seestar refers to it.

The Deep Sky image for this night was the Pleiades.  I let it run for only 25 minutes, since it looked like dew was forming on the lens.

For the wide angle lens, I went back to the Orion area and was able to point it much more south to include Canis Major with Sirius dominating towards the bottom left.  Very dark part of the sky at this location, so it was a good test.

Finally, this last one was nothern Orion and parts of Gemini.

Feb 6th & 7th, 2026 Seestar S50 Images

At the beginning of February,  we had some clear weather, which doesn’t happen too often for this month.  I managed to take advantage of it and produced these 3 images.  One was a short run (The Monkey Head,) but the other two were more involved.

M44 Open Cluster was a mosaic and took a little over 95 minutes to capture (286 x 20 sec.)  The Tadpoles (IC 410) took two nights of imaging and I let the Seestar S50 stack the resulting two sets of sub-images.  It was about 4.88 hrs of exposure.

Caldwell 25 – C25 – NGC 2419 – The Intergalactic Tramp – Globular Cluster

“Lynx is home to the fascinating globular cluster NGC 2419. Although visually faint and small what makes NGC 2419 special is its distance; at 275,000 light-years it’s one of the furthest known Milky Way globulars. In fact, twentieth century American astronomer Harlow Shapley nicknamed it ‘The Intergalactic Tramp’ believing it to have possibly broken away from the Milky Way and headed off into deep inter galactic space. However, recent observations indicate Shapley hypothesis was incorrect and NGC 2419 is still gravitationally bound to the Milky Way just moving in a highly eccentric orbit.” – FreeStarCharts.com

Double Cluster on Christmas Eve 2025

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.

First Light With New Telescope – The Seestar S50

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:
