Description

In this version I try to enhanced the Halpha region, the nebula modules are more visible. It also warms up the center of the galaxy.

----- from the LHaRGB version

I am happy to process again my M81 acquisition data added with almost 4 hours of Halpha to get the nice red nebula modules of the galaxy 's arms.

LRGB : 3 nights despite very high Mistral wind, but nice transparency

Halpha : and 2 another nights for the Halpha
