Description

This is a re-processed duplicate of Michael Southam's "M51 Whirlpool Galaxy". I processed the lights and darks through DSS, applied curves and stretching, green removal, contrast enhancements, background gradient removal, and deep-space noise reduction with PS CS5.

REVISION B: Re-did the whole image starting with the stretched stack of 6 layers in Photoshop, did a "REVEAL ALL" for the center to show the layer under the top two layers with a Gaussian blur, as the layers get less and less stretched as they go down. This allowed me to "un-overprocess" the center of the galaxies allowing them to be better exposed. Also applied a slightly better gradient removal for the background, and lightened the overall image - I think this brings out a bit of the detail better.

All in all, processing this image took less than 30 minutes (total processing time, including stacking in DSS).
