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.

The Elephant Trunk Nebula with the Dwarf 3 telescope.
This is a slightly cropped image of the Elephant Trunk Nebula. Total integration was 3.1 hours. The image was stacked and stars were fixed in Stellar Studio. I then imported the FIT file into Siril, performed photometric calibration, removed the stars, stretched the image, and saved as a TIFF file. I tweaked the TIFF in Affinity 2 and saved as a PNG.

The Wizard Nebula with the Dwarf 3 Telescope
This image of the Wizard Nebula has almost 12 hours of integration time. Individual integration times were 45s and 60s. I used Siril for stacking, histogram adjustment and star processing. Additional processing was performed with Cosmic Clarity and Affinity Photo 2. Bortle 8/9.

The Whole Veil
This is a 2 hour mosaic of the Veil Nebula and Pickering’s Triangle. Stacked in Megastack with initial processing in Stellar Studio and finished in Photoshop.
