Description

Taken under Bortle class 3 skies but in windy conditions and with a slightly under-mounted scope which caused me guiding problems. Consequently, I was forced to drop the exposure times from 300 to 60 seconds to keep the stars round. Probably 30% of the subs were thrown away. This is really a work in progress as it needs more integratioin time but it feels like a good start.
