M31 - Andromeda Galaxy LHaRGB (reprocessed)
Posted by GordonH on Sunday, September 22, 2013 4:34 PM

I wasn't totally happy with the combine of Ha with my LRGB image of this subject as the colour was a bit washed out and some of the detail especially in M110 was lost so I had a rethink and used a different method to combine the Ha in order to keep the original colour and detail. Also as a friend of mine suggested I combined some Ha with the blue channel so that the resulting Ha mix mimics the Hb as well as the Ha hence the magenta colouring of the star forming regions. It isn't so easy to see these regions on such a small image so I've provided a link to the full size image below


Thanks for looking
Best wishes
