M31-G076
M31-G076 is with an apparent magnitude of 14.3mag the fourth brightest globular cluster that can be observed in the Andromeda galaxy. It can be seen under
very good conditions even with an aperture of 8". The absolute brightness of the cluster is M= -10.1mag, which corresponds to a luminosity of 950,000 suns.

Observing M31-G076 is a very easy exercise with my 20" f/3 telescope. The cluster is best seen at a magnification of 270x and more. It then appears clearly
extended and gets brighter towards the center. In its core you can see a brighter, almost stellar nucleus. The GC is located next to two brighter stars that can
serve as landmarks in a smaller telescope.
In addition, the outer regions of the Andromeda Galaxy can be seen, in which M31-G076 is embedded. Every time, this is a very pleasant sight. :)
