Globular Cluster Night

Forecast last Friday night was suppose to be cloud rolling in at 9.30pm so decided to do a quick capture of a globular cluster starting around 6.30pm. Forecast was totally wrong with a beautiful clear night until morning so ended up doing a globular cluster marathon until 3am in the morning
Captured about 1.5 hours of data on each object
It was a long night but enjoyable
