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
