I opened up the big dome around 22:00, very cloudy, however by 23:30 the skies cleared and for about half an hour were wonderfully cloud free, then patches of cloud blew in from the North and it became increasing poor. I closed up around 01:20 when it was nearly 100% cloud cover.
Despite not getting a lot of data the positives are that I can compare the Ha of no moon last night with previous 97% Ha data from a few weeks ago to see the difference. I also added graduated stickers to the Tak so that it is easy to get the same camera alignment between sessions. I also slewed the scope around to find positions to avoid pier collisions.
