Four M's in One Night!

I had a very productive night last week and managed to get four more Messier Objects all globular clusters for my catalog of Messier Objects.  I only have eight left after working on it for over two years now.  It did not start off very well as clouds soon moved in and blocked Polaris so I could not polar align.  I thought it would clear up but it got worse even though it was supposed to be clear.  After an hour I was ready to pack it it in but then it started to clear - I am glad I stayed.

M28 is at a distance of about 17,900 light-years from Earth and is 60 light-years across. It has a combined 551,000 times the mass of the Sun and is 12 billion years old and near the star Kaus Borealis. M62 is at a distance of about 22,500 light-years from Earth and measures some 100 light-years across. M69 is at a distance of about 29,700 light-years away from Earth and has a spatial radius of 42 light-years. M70 is at a distance of about 29,300 light years away from Earth and close to the Galactic Center. It is roughly the same size and luminosity as its neighbour in space, M69 (source: wikipedia).
