Tonight, it was predicted to be a good observing night. In reality, it was a bit hazy in Bowie, but I still sketched M15 (that’s #27 out of 50 for my Binocular Messier Certificate I am trying for). It is a globular cluster about 33,600 light years away, 175 light years in diameter, visual magnitued 6.2. It is believed to be the densest of all globular clusters in the Milky Way galaxy.

Here is my log (so far) for the Binocular Messier certificate.
