Last night I let the scope/camera sit on Messier 3 for four hours, in
hopes of capturing changes in brightness in the many RR Lyrae variable
stars. Since RR Lyrae stars are common in globular clusters, there are

three of the 5-minute unfiltered exposures, each spaced a couple hours
apart, and shows several dozen flickering stars.
