M72 represents the 39th Messier object I imaged over the past 6 months.  It is located approximately 58,000 light-years away in the constellation of Aquarius, contains over 160,000 stars, and 9.5 billion years old.  Although it is considered large at 100 light-years across it appears faint do to its great distance.  I managed to get 18 - 90 second sub-photos out of 32.  Unfortunately wispy clouds moved in.  Although weather was not cooperating I did get a chance to use my new Agena StarGuider II 50mm Mini Guide Scope with Helical Focuser.  It worked perfectly with the autoguider.  The Orion ST80 worked well but I wanted to lighten the load on the mount.  Also, I should be able to use this with my 8-reflector on the mount.
