Re-processing more 🔭 older data, this time C11 the Bubble Nebula, using the newer python tools in #Siril and getting some nice clean images. However, not happy with the bright star, couldn't figure out how to improve it?

Same #Orion data but trying the Veralux Hypermetric Stretch processing script in #Siril It looks more "natural" but it kind of lost the dusty goodness. Thoughts? High clouds keeping me inside tonight. Hope to get more data before it is too far west! #SoCal #Astrophotography

Riccardo Paterniti is developing free Python tools, driven by passion for astrophotography. VeraLux is an independent research project focused on physically-faithful image processing for astrophotography, developed as a Python toolset for Siril.My work explores transparent, reproducible

If you've been using the #VeraLux scripts in #siril for #astrophotography, consider supporting the dev over at buymeacoffee.com/riccardo.paterniti. These tools are 100% free, and have gotten good enough that I'm canceling my adobe subscription, I just don't need photoshop anymore. Ricardo's awesome!

The Witch's Broom Nebula glows with vibrant filaments of red and blue gas. A bright foreground star, 52 Cygni, illuminates the center of the frame, making the nebula look like a cosmic wisp of smoke or a glowing broomstick sweeping through the dark void of space.

Spent another few hours today reprocessing some old data, this time #C34 the witches broom #nebula

Messier 31, better know as The Andromeda Galaxy hangs in the night sky against a backdrop of stars, spiral arms and clouds of dust are fairly prominent in the structure of the galaxy. Two smaller more distant galaxies can be seen above and below Andromeda.

December 2025, The Andromeda Galaxy.

My project for December! Broke the stack limit of the S50 which was less than 2k subs in Mosaic mode. Stacked about 4,700 subs in #Siril.

Telescope: #Seestar S50, 13:03:33 Exposure.

New SHO reprocessed An astrophotography image of the Rosette Nebula in the SHO Hubble Palette. The nebula’s vast gas clouds are rendered in vibrant shades of gold and amber (Hydrogen and Sulfur), while the central cavity glows with a cool, ethereal teal and electric blue (Oxygen). Dark, smoky dust filaments twist through the golden "petals," and the central NGC 2244 star cluster shines with brilliant, pinpoint stars against the blue core.

Original processing A stunning deep-space photograph of the Rosette Nebula. The nebula looks like a giant cosmic rose, with vast, swirling clouds of crimson and deep red hydrogen gas forming the "petals." In the very center, a hollowed-out "hole" contains a sparkling cluster of bright, blue-white stars that look like diamonds resting in the heart of the flower.

Great tutorial on using a range of fabulous scripts for #Siril

I think I can probably improve if this, but, really pleased with this result.

Can someone explain why the blue color is almost gone? 👀
