NGC 2264 – the Christmas Tree Cluster & Cone Nebula! I did the composition in SHO. This deep-space view reveals incredible detail and contrast. A rewarding target to image and process—hope you like it! 🔭 #astrophotography (78×300s Ha / 64×300s SII exposures over 2 nights) @kat-astro-bot.bsky.social

The Whirlpool Galaxy (M51) – a stunning cosmic dance 31 million light-years away!
Over the past two nights, I captured it for a total of 8 hours of exposure. Hope you enjoy this glimpse into the cosmos! 🔭 #astrophotography / C8 EHD

A seasonal classic—the Orion Nebula (M42)! ✨
Though often photographed, its extreme dynamic range makes it a real challenge to capture in detail and process properly. Thanks to great advice from the #astrophotography community, I managed to bring out this version !

Holy moly ! I got 2 clear nights in a row :) Let's celebrate that with the horsehead and the flame nebula :) I managed to capture 2 and 1/2 hrs of signals (clouds ... still clouds). #astrophotography.

Have you ever seen an R2D2 brain? Well, now you have.

J'ai fait bcp mieux ensuite. En 2023 avec un champ plus grand. On distingue quelques IFN

Here's my latest SHO processing of the Pacman Nebula (NGC 281).
I captured the data earlier this year between August and September, with one night dedicated to HaOIII and two nights to SII/OIII. Happy to finally share the results!

The Little Rosette (SH2-170), a nebula in the Cassiopeia constellation, shining 7500 light-years away!
Sadly, November’s cloudy skies gave me just one precious night to capture it.

Entre deux nuages, on arrive quand même à capturer la comète du moment (C/2023 A3), zu Lëtzebuerg

Enfin quelques nuits étoilées ! J'ai donc pu reprendre la photo ;) Et dans ce ciel d'hiver on trouve notamment l'amas des Pléiades (M45), qui éclaire la nébulosité qui l'entoure.

A season classic, the Andromeda galaxy (M31), but quite happy with the result :) I made this image as a mosaic of 2 panels. Each of them with about 5hrs of total exposure, captured across several nights in September and October. (FRA500 / asi2600mc / IDAS LPS-P2)

15. A very very difficult target, the squid, inside the the flying bat nebula. The squid is faint on this picture, but I acquired about 20 hrs of exposure to get it like that. Need more signal :)
