Tom,
Great job. It's surreal how those stars are blinking on and off. I bet you
could convince people that it's really alien civilizations signaling from one
star system to another!

Subject: [AZ-Observing] Variable Stars In M3
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 plenty of similarly
bright comparison stars nearby. This sequence used three of the 5-minute
unfiltered exposures, each spaced a couple hours apart, and shows several dozen
flickering stars.
