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.
Processing:
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.
