Voici l'ancienne si vous voulez comparer, faite avec PixInsight, que je pense bien maitriser. Pour être transparent, 90% a été fait sur Siril. Quelques détails ont été finalisés sur Pix. Mais Siril est libre, gratuit. Une pépite. Vraiment. Si vous voulez apprendre, je vous le recommande le livre 🔽

One of my simplest images in terms of exposure and processing… yet one of my favorites. Dust and gas clouds weave with distant, reddened galaxies — not the death of a star, but the cradle of many new ones.

Have you ever seen evidence of a black hole's existence? Particularly in amateur astrophotography? Take a look at this image here. Do you see it? This is an image taken with Red, Green Blue, OIII and Halpha filters.

No, Siril is not just software for amateurs. Professionals are using it, and this has become even more apparent since our last publication in JOSS.

OU4, the Giant Squid Nebula, is one of the most stunning deep-sky objects — but also one of the trickiest to capture. This image combines multiple filters: R, G, B, Hα, and O III to reveal its incredible detail and structure.

A month ago I posted about an Einstein Ring which I photographed with my backyard EdgeHD 9.25”. Since then I added more data (611x180s) and with careful processing it got a bit clearer still. See

Prise de vue incroyable, par le télescope spatial James Webb, de cet immense jet de gaz produit par une très jeune étoile en formation (située en-dehors de l'image, en bas à droite). Par une coïncidence cosmique, l'extrémité de ce jet protostellaire passe juste devant une galaxie lointaine. 1/4

Yes, I know. Still no version 1.4.0. But everything's going well. We're at the bug-fixing stage. Also, script creation is progressing very quickly. Here's a sample script from SetiAstroSoftware -> NB to RGB. Screenshot taken on macOS.

We may be considering abandoning AppImage binaries, as it's becoming difficult for us to maintain them. However, if we could find a volunteer to maintain and debug them, we could keep them. Please contact us.
