Description: Minor color and level adjustments performed. Added lum info from 3 close-up 16" SCT pictures as mentioned here:
http://astrob.in/312209/0/

Used a HP filter with a mask on the dark info. in the galaxy.
After reduction to 33% 16bit tif size/format, the stars were/looked too dominant in the picture=>Select stars and feathered gaussian blur action was performed and I also used a fade min filter with a given opacity to reduce the dominant star look in the reduced sized picture.
Kind regards Niels
