Had an ok night last night.  I pointed away from the quarter moon to the north, in Draco, but the seeing was not very good -- probably roof currents -- so while I started at 20-inch I masked down to 8-inch.  A couple nice finds.  I started at 10:00pm and was shut down early due to marine fog at 11:30pm
