The North America Nebula
It’s remarkable how far small scopes and semi-automated processing have advanced. I am loving the new Dwarf 3 software update. This image is a scheduled mosaic of the North America Nebula using the D3. The image is 140 x 45s mosaic frames. I stacked it in Megastack and did initial processing in Stellar Studio—both provided woth the D3. Final processing was in PS Express. I’m quite pleased with the result.

Leo Triplet (Seestar S 50)
5 hours on the Leo Triplet in EQ mode. I'm impressed with the amount of detail the scope captured in that time (zoom in to see it). Bortle 8/9. Processed in Siril, SETi Astro, Graxpert, and Affinity 2/JR Macros.

The Moon on April 8, 2025
I finally got around to processing an image of the Moon captured at the beginning of the month under exceptional seeing conditions. This image is a stack of 700 from a total AVI capture of 1400 frames. Stacked in Autostakkert, wavelets in Registax 6, and the size of the final image was doubled in Astrosurface.

The Tulip Nebula—Hubble Palette
This image is just over 3 hours of integration on the Tulip Nebula. The image was stacked with star processing, initial histogram stretch, and Hubbleization in Siril. Main processing in SETI Astro Suite (with Cosmic Clarity), and further tweaks in Photoshop.
NGC 2064
77 minutes on NGC 2064. I tried a new workflow: stacking and star removal/restoration in Siril, noise reduction and background gradient removal in Graxpert, image enhancement in SETI Astro Suite, and final tweaks in Photoshop.
The Moon on April 4, 2025. Seestar S50.
The Moon under exceptional seeing on April 4, 2025. A stack of 500 from 1000 captures with 2X enlargement.

The Sun Today--April 4, 2025
The Sun today, showing some interesting spot groups. The spots in two linear groups toward the center of the image, has the potential to produce M-Class flares.
