This is an image of Grus Triplet. This group of galaxies is about 60 million light years away in the constellation Grus and is comprised of NGC 7582, NGC 7590, and NGC 7599. These three galaxies along with NGC 7552 make up the Grus Quartet, which is part of the IC 1459 Group. This image contains data taken from a CDK17 and RCOS 12.5 and represents over 57 hours of total exposure. You can mouse over the image to see an annotated version that shows just how many galaxies are in this image. I also posted a cropped version that shows more details in the triplet.
