NGC 2366 belongs to the M81 group which is about 12 Million light years away. The first thing you will ask yourselve is why the nebula at the top of this galaxy appears blue and not red. We don't know, but if you calibrate the image in the usual manner, the color comes out blue/green.
In the center of this nebula there is a super massive erupting Luminous Blue Variable star with about 30-60 sun masses. It cannot be resolved in this image from the cluster.
