Description

Due to my ongoing problem with wrong colors in fits images stacked in DSS, I have been trying other formats while capturing images using CCD Ops. This image was taken in compressed fits format and the subs were converted to color tiff in CCD Ops and then stacked with darks in DSS. Compressed and uncompressed fits images do not stack in DSS, so that is why I had to convert to tiff before stacking.

The stacked image was then given levels and curves adjustments in Photoshop in addition to background smoothing as outlined in R. Scott Ireland's book "Photoshop Astronomy" . Finally the image was given additional smoothing in Noiseware and framed using Carboni's Astro Tools.
