Well this is work in progress!
I finally got a chunk of night with no moon and clear skies, so my camera has been taking 1 minute 20 second subs of Andromeda Galaxy for the last hour, and I've now changed the batteries.
I have no idea how well it's tracking or if the focus is bang on :-0 but he exposure seems to be pretty good.
If it can stay clear until 11:30 I hope to have something worth showing off tomorrow….
