The Bubble Nebula--16h with the Seestar S50
This is a cropped image of a 16 hour integration (EQ mode, 20s exposures). It was processed in Siril, Graxpert, Cosmic Clarity, and Affinty. The Seestar pulled out some nice detail for such a small aperture. I may try with even more data, if the skies ever clear here in NC 🙂

WR 134--8 Hours with the Seestar 50
I need a lot more data to get a good image of this object: WR134. WR 134 is a Wolf-Rayet star with a typically very high surface temperature and strong stellar winds. The whole ring-shaped shock nebula is not visible in this image, but part of it is (the blue, curved structure). I haven't seen an image of this object with an S50, so I thought I would try to see if I could capture it. This image has 1510 x 20s exposures in EQ mode. It was processed in SIril, Graxpert, and Photoshop.
Here's V2, with slightly more aggressive processing :)

Elephant Trunk 26 hours processed in Siril, Seti Astro Suite and Cosmic Clarity
Here's he same data as my last Elephant Trunk post processed in Siril and Seti Astro Suite/Cosmic Clarity. The differences are quite interesting. I think I prefer this version.

A 26 hour integration of the Elephant’s Trunk Nebula
This image of the Elephant’s Trunk Nebula consists of 26 hours of 1 minute integrations. It was stacked and the stars were fixed in megastack and stellar studio. The image was further processed in Siril and Photoshop.

The Lagoon Nebula with the Seestar S50
This is probably the best image of the Lagoon Nebula I have ever taken. The Lagoon is a tough object for me as my southern horizon is mostly tall trees. I also live in a large city--about a mile and a half from downtown in Bortle 8/9 skies. I do have daughter who lives in Indiana and I took the S50 with me on a recent visit. I'm glad I did. She has Bortle 5 skies and conditions were excellent for imaging. This pic is a crop of the nebula. The image has a total of 1.5 hours of integration time. It was stacked and stretched in Siril, with star processing also in Siril. I processed the resulting image in Cosmic Clarity, and tweaked it in Affinity and Photoshop. I'm amazed at the detail the Seestar was able to pull out. I kept saturation and brightness low in order to show the maximum detail, which washes out on a brighter image. EDIT--just added another version of this image, with the gradient fixed in Graxpert.
