Description

This is a really tough target for me to image from my backyard. I have an obstructed view of it so I can only manage about 2 hours per night on it. As a result, I decided to cheat a bit with the processing. I was able to collect about 2 hours each on the R, G and B channels. The signal looked pretty strong so I created a synthetic luminance layer using the RGB channels and then processed as an LRGB image.
