Description

I used this bright globuiar cluster to experiment with some different guide algorithms in PHD2. Despite the combination of a bright 1st quarter Moon in the sky and imaging during astronomical twilight this came out pretty well, certainly much better than my only previous attempt nearly 4 years ago with my Canon DSLR and 4" APO.
