Description

Hi! This is my 3-hour Ptolemys cluster image integration and processing attempt @ fair weather...this is one of my difficult images I tried to take... and after that I had to face and begin removing the inumerous "glitches and challenges" of this simple image! I could crop the bottom to remove some artifacts a little bit but I want to keep the two stars...Hope you enjoy ! :-)
