Description

HαRRGB combination of UHC-S data from 12 Mar 2013 and Hα from 8 Jan 2015. R channel is 20% from UHC-S, 80% Hα. That same combination was used as luminance at 80% transparency. This image shows a lot of the “blue star” problem I often have with HαRRGB images.

The B revision is an attempt to follow Matt McBee's suggestion to desaturate the blue stars.

The C revision has more boosting of the R channel.
