Description

I'm finally getting around to sharing some of my pics processed with the new software I'm learning -- StarTools. Here' M 13. Lots of blue stragglers, assuming I got all the star colors right. And notice the little smudge at the lower left? It's not NGC 6207 -- that's further from M 13 and I cropped it out. This little smudge is:

IC 4617 (magnitude 15.2)
0.036490 redshift
500 million light-years
