Les Pléiades est un célèbre petit amas d'étoiles dont une dizaine est facilement visible à l'œil nu dans le ciel
Elles sont au centre d'une structure bien plus vaste contenant un nombre considérable d'étoiles réparties sur plus de 600 parsecs, maintenant appelée "Complexe des Grandes Pléiades"

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.

Quick teaser of a new script I'm working on for @siril.org. Works for non-smart scope images (but also some smart scopes). Beta testing will start soon. Testers in my discord & Patreon Patrons (including free members) will get access to test: patreon.com/naztronomy

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 bit of tweaking of the previous post - Omega Centauri NGC 5139, the largest known globular cluster in the Milky Way - imaged from the backyard. 1.5h of data collected with a Takahashi TOA 130 telescope and ZWO ASI533MC camera. Processed in @siril.org and #GIMP. #astrophotography #astronomy
