2E 166, Globular Cluster in Andromeda
Also called G280. It's been a while since I processed some ACS/HRC (Advanced Camera for Surveys High Resolution Channel) data. It's been broken for a long time, but there are still archival data that are nice to have a look at. As its name implies, the ACS/HRC was great at seeing fine details in even small objects like globular clusters in our neighboring Andromeda galaxy.
There is a green star in the upper right quadrant of the cluster, but that's probably just a variable star. The data weren't collected all at the same time.
Data from the following proposals were used to create this image:
Metallicity Spreads in M31 Globular Clusters
Search for Black Holes in M31 Globular Clusters
A Panchromatic Hubble Andromeda Treasury - I
Red: ACS/HRC F606W+WFC3/UVIS F814W
Green: ACS/HRC F555W
Blue: WFC3/UVIS F336W
North is up.
