M31-G010



M31-G010 is a globular cluster in the Andromeda Galaxy, which has an apparent magnitude of 17.0mag. This corresponds to an absolute magnitude of M= -7.4mag or only 80,000 suns. So it seems to be a rather small and faint globular cluster.

I observed the globular cluster "G010" only because I wanted to know how deep I could get with my 20" f/3.2 telescope. Unfortunately the night was very humid and during the observation the secondary mirror was even slightly thawed. So I could not see more than an extremely faint, diffuse patch of light.

But hey, in better conditions I can surely get a little deeper than the given 17mag. :)
