M83 The Southern Pinwheel galaxy

Image Description and Details :

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 spiral
So 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 high
Blue 20 subs@300s -20°C bin 1 gain high
Green 20 subs@300s -20°C bin 1 gain high
Light 30 subs@60s -20°C, gain high
Light 39 subs@300s -20°C, gain high
Light 81 subs@600s -20°C, gain high
Halpha 45 subs@300s -20°C, gain high
Total exposure : 26h05
