I managed to take an hour's worth of data (4x15minutes) last night in the backyard before the high thin clouds started to move in.
This is an interesting area. The seeing was pretty soft, but the 150mm lens fortunately isn't so sensitive to seeing conditions with an image scale of about 9.4 arc-sec/pixel. It would have been a lousy night for using the 18" cassegrain for sure: Procyon was flashing like a searchlight :-)
