Description

This uses RGB from 23 Dec 14 and Hα (combined with the R channel and as luminance) from 30 Dec 2014. I would have preferred to have a bit more Hα, and probably should have used 900 s exposures rather than 600 s. This target is quite dim. Nevertheless, the HαRRGB looks a lot better than the RGB alone. I stretched the Hα much more aggressively than I did for the Hα image by itself.
