Description

Processed from dataset named hlsp_heritage_hst_acs-wfc_m51_f814w_f555w_f435w_v1_drz, found at:

Processed in PI with minimal cleanup in linear, a little bit of HDRMT post stretch and some color work to enhance structural contrast. No detail enhancements or sharpening of any kind - the data is so gorgeous that I didn't want to risk taking anything away from it. :-P Take a look at full rez, but be warned: the image file is pretty large, even after a 50% resample.
