"Stacked from 15 exposures of 1/5 second at ISO 100 This image is a mosaic of 15 separate and slightly overlapping 8.2 megapixel images from my Canon EOS-20D (unmodified), taken in Raw mode and converted and stitched together in Photoshop CS2. The exposures were each 1/5 second at ISO 100.
I mounted my 20D to my Meade LX200 GPS UHTC 10" Schmidt-Cassegrain telescope via my 2x Televue Powermate (a focal length doubler, similar to a teleconverter, which also serves to mate my camera to the 2" telescope eyepiece tube). Effective focal length was 5000mm f/20.
Looking through the viewfinder I swept across the surface in a zig-zag fashion, trying for about 1/3 overlap between frames. I triggered the shutter with my TC80-N3 remote timer/controller. I did the stitching by hand in Photoshop.
Since it was taken at the camera's most noise-free setting (ISO 100), the data is very accurate, and thus I was able to strongly increase the saturation via Photoshop's Image - Adjust - Hue/Saturation function."
