NGC7000 - The North America Nebula (HaRGB)

21:59 6/9/2006 UTC

Finally I got to image colours to my North America Nebula. Almost full Moon was up in the sky while taking colour shots, but conditions were favourable enough for shooting star colours (meaning no clouds...). This image is combined with my previous Ha image using (Ha+R):G:B technique. Ha data is added to red channel.
