Finally had some luck with the seeing, despite the jetstream looking ominous. The temperature dropped quickly after sunset but the active cooling helped bring my mirror down to ambient temperature. The seeing started off below average but settled nicely for a period of an hour or so until the jetstream kicked in at about 11pm, not helped by the temperatures which dropped a further degree in the space of 10 minutes.
I missed the best of the GRS but it was nice to see what it looked like - it's been a while since I've been able to image it in better than average seeing.
There appears to be another spot approaching the GRS at the same latitude as the LRS did - it even appears to be the same size as the old LRS but it's just not red/orange in the middle. What is it?
12" Newt, 5x powermate, DMK21AU04. 30fps for ~52 seconds in each channel.
There may be more from the session coming later but these are probably from the best of the conditions.
Thanks for looking.
