This image is a test under horrible conditions. The
Moon was nearly full with temperatures in the 70's and humidity in the 90's.
The goal was to test the Lumicon broad band filter from the old TechPan days as
a filter for the Canon modified DSLR.
This is a very quick processing just to see if the data was of good quality so
that I may continue using this technique this evening.
The image is exclusively from the red channel of the RGB raw file and has been
contrast stretched in PS3 with star reduction in Images Plus and noise reduction
in Noise Ninja.
