Ended imaging at 5:30am
Beautiful night slightly windy 0.9’ seeing at first but then changed dramatically later to around 2.2’
Markarian’s Chain suffered from many satellite trails, more so early on.

12 x 300s so 1 hour of Markarian’s chain
By the time I started to image M39 the wind had started to pick up and I found even guiding at 60s was causing star trails.
M39 single 5 mins sub
So about 3am I started taking darks and then by 4:15am the seeing which was really the problem had settled down from 2.2 arc secs to 0.9! I went back and took 30 x 60s subs for M55 and then another 30 x 60s for M39 before heading off to bed.
