Details:
In quarter moonlight. Could not have been simpler and I've seen worse: c. 25x 90sec exposures @ ISO 800 thru 71mm Williams triplet with unmodified T2i. Starry Sky Stacker including c. 10 darks which may have helped contrast. On entry level Skywatcher EQ-35 "Pro" leveled with $3.29 metal bubble level from Harbor Freight. NOT computer-assisted tracking with PHD, etc. which I have not found nearly as iportant as physical leveling the mount head on the E-W. The tripod bubble is useless partly because the gear-head on it is not inexactly the same plane.
