I'm actually quite pleased with this one! Used PixInsight's NBRGBCombination script to enhance the red using Ha, and then the Ha channel as luminance. Doing that brought out some background nebulosity that I did not expect at all! I'm wondering what that little red ball is on the right side -- it's not showing up in SkySafari.

Update -- the little red blob on the right side is Sh2-247. Thank you Elmiko!
