Thanks Stuart & Marc, I appreciate your comments.
Apart from the seeing dropping off as the early morning crept up, the main challenge was having just 210 secs to do a Meridian flip, acquire the field, acquire a guide star, start auto guiding and then kicking FireCapture off again to grab more AVI’s.
It’s a real shame that the worst seeing was when Europa’s shadow began to creep across the Jovian disc.
Cheers
Dennis
