Messier 13 (M13), also designated NGC 6205 and sometimes called the Great Globular Cluster in Hercules or the Hercules Globular Cluster, is a globular cluster of about 300,000 stars in the constellation of Hercules.
Got an unlucky night, my EQ6 mount stop guiding fine for more than 100 sec, so i'd tryed various settings on synsca, on lacerta, redo much times alignment, checked all the tightenings, with and without shorty barlow on guide telescope, but still unsolved. I was convinced that with the test at home months ago, I had good guide for 500 sec, but this last week not more than 280 sec .. and now 100, is in a free fall !!
hope to solve soon, for now I have to content myself :)
