SPX350 F39, PGRFlea3, Baader RGB filters. 1230hrs UT
A breezy night with good seeing forecast, but seeing was avg and wind persisted. I could only grab 200 frames each channel quickly before cloud came. 13,700mm fl is too long as RGB was only 3fps at 50% hist, may try again some time at F29.
Thanks everyone, will have to try in IR to see if there are any spots like Bird showed. I found Uranus quite quickly in viewfinder, Neptune will be far harder if I ever give it a go.
