Hi to all
Just for the sake of completeness and the fact that there was nothing better to do with the moon being almost full I added 4 hours of Hydrogen Alpha to my NGC 55 image. While the added Ha version certainly makes the HII regions stand out the LRGB has better stars I think. I'm not sure how I managed to mute the stars in the Ha version.
Cheers
Steve
