NGC 6633 open cluster in Ophiucus. A large cluster consisting of about 30 stars at slightly over 1,000 light years distance. Its age is estimated at 660 million years. Taken at Cherry Springs State Park the morning of June 29th 2016 Celestron C8 @ F7.5 with Starizona reducer\corrector 1500mm EFL QSI583wsg, Baader filters RGB16 each at 2 minutes binned 3x3 (I forgot to change the binning after centering) Total exposure 96 minutes Faux diffraction spike added with Noel Carboni's Astronomy Tools. My apologies to the purists.
