The color negative of the full moon looks very similar to the moon during a total lunar eclipse. This exposure (below) was taken with my 10″ f/4.5 Newtonian with a primary mirror figured and coated by Optic Wave Labs (OWL). I did very little in the way of processing the RAW file. I ran the Noise Ninja plugin to cut down on the color noise inherent in DSLRs and to sharpen things up slightly. Then I used Photoshop’s builtin color negative effect to invert everything.
