This galaxy cluster lies in Corona Borealis and is around 460 million lightyears distant. There are dozens of galaxies within the frame of this image, but the two largest are NGC 6085 and NGC 6086. The former is the spiral galaxy below the middle of the image – and huge at around 226,000 lightyears in diameter. NGC 6086 is the elliptical galaxy in the centre, even larger at 250,000 lightyears.
This image is the result of 1h45m of remote data capture from New Mexico, over two evenings in July 2022. A Planewave 20-inch CDK reflector was used, with an FLI ProLine PL11002M CCD camera.
