Description

Complete new version with new RGB in bin 1 this time: I tried to keep as much as possible the faint details in the hapha globules and enhanced the spiral

-----------------

Another nice project made with Olivier Désormières from the SADR Team

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
