Globular Star Clusters M53 and NGC 5053
Two star clusters within the same small field of the sky about a degree apart, but vastly distant from us and about 1,000 light-years apart from each other. M53, at upper right consists of many thousands of old stars formed at around the same time. NGC 5053, at lower left is much looser and contains fewer stars.
A composite of 30 frames, 5 hours total exposure. Explore Scientific ED102 102mm f/7 refractor, ZWO ASI294MC camera, UV/IR cutoff filter, iOptron CEM25P mount, ASIAir controller. Processed in Astro Pixel Processor, and Lightroom.
