Description

M13, the great globular cluster in Hercules, is among the most spectacular of the Messier objects. This imagewas taken in LRGB mode with 100 luminance subs of 60 seconds each at an image scale of 0.46"/pixel. It was acquired on a humid night with unusually good seeing for my location. The average FWHM of the subs was 2.27", and the best was 2.00".
