First light of ATRIA observatory, one of the most beautiful galaxies from the Fornax NGC1365 and NGC1097 with a PlaneWave CDK17 installed at Deep Sky Chile. ATRIA team composed of 6 members: Olivier Désormières, Fabien T., Frédéric L .. David Néel, Julien Bourdette, and myself ;-) Arnaud PeelI try to keep as much detail as possible for a close-up view. I specifically process the center core of the galaxy to keep the colors and the detail at the maximum of the resolution of the acquisition FWHM< 1.6" .Processing: Arnaud PeelTotal exposure : 11h15Red 18subs@420s -15°C gain highGreen 20 subs@300s -15°C gain highBlue 20 subs@300s -15°C gain highLight 165subs@180s -15°C, gain high

Another nice project made with Olivier Désormières from the SADR Team (acquisition Arnaud Peel and Olivier Désormières, processing Arnaud Peel): a complete new version with new RGB in bin 1x1 this time: I tried to keep as much as possible the faint details in the Hapha globules and enhanced the spiralSo thanks a lot to Olivier for the acquisition of a great Luminance and RGB with the Sadr association setup , Newton 14'' in Chile.I select the best FWHM subs for the luminance.60s subs were made not to burn the center of the galaxy.Red 20 subs@300s -20°C bin 1 gain highBlue 20 subs@300s -20°C bin 1 gain highGreen 20 subs@300s -20°C bin 1 gain highLight 30 subs@60s -20°C, gain highLight 39 subs@300s -20°C, gain highLight 81 subs@600s -20°C, gain highHalpha 45 subs@300s -20°C, gain highTotal exposure : 26h05

Messier 81 (also known as NGC 3031 or Bode's Galaxy) is a grand design spiral galaxy about 12 million light-years away, with a diameter of 90,000 light years, about half the size of the Milky Way, in the constellation Ursa Major. Due to its proximity to Earth, large size, and active galactic nucleus (which harbors a 70 million M☉[5] supermassive black hole), Messier 81 has been studied extensively by professional astronomers. The galaxy's large size and relatively high brightness also makes it a popular target for amateur astronomers.
