NGC 206
Star cluster

Description

This image shows NGC206.  This object is a massive star cluster (one of the largest in our local group of galaxies) in the Andromeda galaxy, M31.  This cluster consists of hundreds of massive blue stars with several having apparent magnitudes of around 18.  This cluster is also knows as an OB association (with a nomenclature of OB78).  This cluster is likely less than 10 million years old and lies in a spiral arm of M31 (likely where two spiral arms are intersecting).  It spans across an area of around 4000 light years.

As with my recent M32 image, this image contains several of M31's globular clusters and I need to make an annotated image to show these.  I also would like to get some Ha data and add that into this picture.
