The Abell 426 galaxy cluster in Persus is about 270 million light years away. I was able to identify 45 galaxies in this image so far (hover over with mouse to see labels). There are still 9 fairly bright galaxies I wasn’t able to identify. There are at least 54 galaxies in this image. This image covers only the central part of the cluster, which contains hundreds of galaxies. Many of the galaxies in this image aren’t in TheSky’s database of galaxies. I increased the brightness of this image more than I usually would, so as not to hide any of the dimmer galaxies. Also known as the Perseus Cluster. It is one of the most massive objects in the known universe.
