Double Cluster Redo

I've been going back through my image archives and reprocessing some of the older images to see if I can improve them. Here is a reprocessed version of the image of the Double Cluster that I shot back in September 2009:

Another Coathanger Redo

This is a reprocessed version of the Coathanger Cluster that I posted back in September 2010. I reduced the size a bit to hide some of the image noise.

North America Nebula Redo

This isn't exactly a redo of my original North America Nebula. I had been intending to try to remove the effects of chromatic aberration in the stars for some time, but found it a somewhat difficult task. Most of my attempts left unnatural looking holes in the nebula, so I settled on desaturating the purple fringes and colorizing them to more closely match the color of the nebula. This is fine for the stars that are surrounded by the nebula, but those that are surrounded by darker parts of the image now have red halos instead of purple ones. Oh, well. One of these days I might win the lottery and get a nice little apochromatic refractor.
