Enjoying the skies of the Southern Hemisphere!
A real pleasure.
Only [OIII] and RGB, I didn't have time to photograph Halpha.

This is a mosaic of the Heart Nebula. I really like the result.

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.

M27 like you've maybe never seen, lying on a hydrogen sea.

Amateur imaging cannot observe in the X-ray domain. However, for the jet coming in our direction, a bow shock occurs when the matter meets the interstellar medium and this phenomenon is then visible.

It took until 1971 to understand that this X-ray source in Cygnus was actually a black hole with an orbiting star. Matter spirals into the black hole, forming an accretion disk, with two perpendicular X-ray jets.

But in Cygnus, there's also an "anomaly" detected in the 1960s. A very bright one, the brightest in the sky, in X-rays.

This is the Cygnus region, with the Tulip Nebula. A nebula very well known by astronomers.

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.

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.
