NGC 4236 - Galaxy in Draco

Processing Attempt 2

This version was done a little differently. The same combined and DDP'd channels were used, but this time a copy of the Luminance layer was deconvolved first. I then placed the L copy under the original L layer, and erased just the deconvolved sections I wanted.

Processing Attempt 1

This version was actually the second attempt. A little too much noise reduction and histogram stretching led to some very 'blocky' and strange areas in the background.
