Description

Dumbell M27 in RGB

2 nights the 2 and 3 septembre

20 Red subs @180s (gain 139 and -20°c )
19 Green subs @180s (gain 139 and -20°c )
18 Blue subs @180s (gain 139 and -20°c )

I use the superluminance technic to make the L and process it before adding it to the RGB.
I also use a new stretch technic to keep the colors of the star and not clip the hight ADU values
