Description

In my effort to learn how to do HαRGB combinations, I have been struggling. I tried the Starizona Photoshop methods and just could never get things even close to right. So I finally used a button I've never used before in StarTools, the LRGB button. I just put the Hα in for luminosity and used an old, prealigned RGB image. On the first try I got a better result than I've been able to produce after hours of messing around with Photoshop. This is the result.
