Open clusters, like globulars, make for good targets when the Moon is full, or nearly so. I actually was guiding when taking these short subs, but I quickly learned that a bright moon and long exposures don't mix. 20" was about as far as I could push it without the entire frame being a brilliant white. Question: Might taking such over-saturated subs be a good way of acquiring flat frames? The question just occurred to me as I was entering this. Feedback on this topic is welcome.
