Description

Took some poor subs for this in May. Added some better ones last night including the RGB for the stars. This is a blend of the good, bad, and the ugly. Making a cotton purse from a pigs ear.

Still a nice Pn from the Abell list.

Rev A: The RGB with a STF applied this made sure the stars were larger than the poor NB stars.

Rev B: The H HO O RGB stars added then an extracted Luminance is applied.
