Description

This is a combination of 2 nights worth of data from 2015 and 2017. I did a kind of strange processing flow here, doing a SHO with Ha as luminance, performing a star removal using Straton, performing an LRGB combination of the RGB with the Ha as luminance, and then layering back on the Ha-RGB stars.
