Object and Imaging Notes
The composite luminance channel (below) is a combination of the pure luminance and Hα. I actually ended up not blending the Hα in to the color. The RED channel had enough data that, with the Hα luminance support, it was sufficient.
There is a nice little reflection nebula around the star just to the right of TYC3156-1027-1. It's a very subtle blue and it's barely visible on the half resolution image. It shows up nicely in the full resolution version.
