Just a quick globular cluster. This one is in the Small Magellanic Cloud. Some background galaxies are scattered between the stars. The most prominent one is an elliptical galaxy in the upper left but there are a lot of spiral and lenticular disks peeking through as well.
This was part of a study on star clusters in the SMC measuring ages of stars and a bunch of other stuff I will not attempt to paraphrase because I'll probably get it wrong. See for yourself here*. Thanks, people who did proposal 10396!
