Description

What to do during galaxy season with a full moon!? This one came out pretty well considering how close it was to the nearly full moon and the short time involved. I think this is my 4th attempt on M13 and finally something I am pleased with. The image is cropped from the full frame due to some vignetting that didn't fully correct with flats and is resampled 50% to meet Astrobin size restrictions.
