Abell 2151 is a cluster of over 200 galaxies. I’ve spent the last three weeks collecting over 32 hours of data on this cluster. There were some problems with neighborhood light pollution, so I had a nasty background to contend with. Luckily, I was able to mostly fix it up.
There are 254 annotated galaxies in this image, most of which are around 400-700MLy away, the brightest of which are 13.5 magnitude. There are also some far more distant galaxies that are not included in the catalogues I used. It’s incredible to see how many of them are colliding and interacting.
