 Taking a large color composite of the full moon has always been a plan for me, but dealing with huge numbers of RGB filtered images and trying to get the color correct has steered me away from this project. This has all changed with the 10D. This is 9 part composite with the 12.5 inch and 2x Televue Barlow making the original 400 Megabyte file worthy of a huge enlargement. The panels were all identical in color balance, sharpness and field making the compositing a snap. I was never quite able to get the color panels with my RGBB shots and my ST8i to match up. IF you have the bandwidth, the largest image is worth the download time.

Ok, so why color and not a plain greyscale image of the moon? The moon has subtle color variations that you can see when you convert to greyscale and compare to the original. Tranquility has a bluish tint, Serenity and Imbrium yellow-green. The basalt verses more siliclastic minerals on the surface are the source of subtle colorations.


Images were identically mid tone adjusted automatically in PS. PixInsight was used for wavelet processing to correct for slightly soft seeing, and images were combined in PS with layers and feathered edges.
