yes Mike - when the seeing is as bad as 4.9 arc seconds it's not worth proceeding -
all you get is a blurry mess but -
when you've gone to all the trouble of setting
the system up it's hard to resist taking some kind of image.
Some nights I measured as bad as 6 arc seconds FWHM.
I think the best night I ever got in Melbourne was 2.9 arc seconds
FWHM and that was only between 2 am any 5 am using an Ha filter.
Your results getting between 1.5" and 1.8" over the more than 27 hours of data collection
are very impressive and from a dark site as well.
cheers
