Messier 13, aka The Hercules Cluster, is a ball of about 100,000 stars pulled together by gravity. According to NASA, the density of the stars in the core "is about a hundred times greater than in the neighborhood of our Sun. These stars are so crowded that they can, at times, run into each other and even form a new star." The bright star to one side is a variable, HD150998. My image was made - with a bright, almost full Moon in the sky - from the best 70% of several hours' worth of 10" exposures, gathered in the garden in Colchester UK on a ZWO ASI585MC camera with Baader Mk III MPCC coma corrector and ZWO UV/IR cut filter, on a Sky-Watcher Explorer 150p and EQ5 Pro mount, via Stellarmate Plus in Kstars/Ekos. Stacked in AstroPixelProcessor, cropped and adjusted in Lightroom and Photoshop, tweaked with Topaz DeNoise AI.
