Description

This object is positioned nicely for me to capture from 10 PM to 5 AM. I used this time to capture 3 hours of Ha and 2 hours of Luminance. I then layered this over RGB I had from July 2015. Final image is LHaRGB. I used a "Screen" layer in Photoshop to help merge the details in L and the color in HaRGB.

Description: Used OAG for L rather than ONAG. Not yet sure if ONAG has an advantage for my equipment and conditions.
