Description

I know, I know... This target has been processed many many times. But it's too attempting to pass. The data from MAST (https://mast.stsci.edu/portal/Mashup/Clients/Mast/Portal.html) is simply great. Very clean FITS files. Warning - this set of files are HUGE!

Target: NGC 4594 (M104)

RGB combined in PixInsight (PixelMath). Cosmetic touch-ups done in Photoshop. Final process completed in Lightroom.

ACS/WFC: F435W
ACS/WFC: F555W
ACS/WFC: F625W

Color Mapping (PixelMath):
Red - 0.8*F625W + 0.2*F435W
Green - F555W
Blue - 0.2*F555W + 0.7*F435W

The fun part of this processing is to remove the charge spikes and big & colorful halos around the bright stars. Glad I got them done!
