Even though we have had non-stop rain for what seems like weeks somehow the evening of May 1st was completely clear, although there was unfortunately a blazing Moon overhead.  Never mind, can still do star and star cluster shots.  So this evening I captured the brilliant blue star Spica (not processed yet) and this globular cluster, M13 in the constellation Hercules.  I really like M13 and have imaged it on many occasions.  Although the collimation wasn’t too good on the Hyperstar (I didn’t spend any time tweaking it) the result of 68 subs at 1-minute per sub speaks for itself.  I will do this one again, with better collimation, and with slightly shorter subs as well so that I can clearly define the core of the cluster.
