Description

This is a LRGBHa of 120+55+28+28+29 subframes. For the details i sort out the best Luminance data by FWHM, and stack them separately to build the highlights from them. For the Details i use 72 Pictures to build the highlights.

I used for the LRGB Gain 0 and Offset of 10 (-15°C)

For the H-Alpha i used Gain 200 and Offset of 40 (-15°C
