Variable stars in Messier 15. This bright globular cluster in Pegasus contains quite a few short-period variable stars. Jim Mazur used four images, taken about 1 hour apart, to make this loop, which shows at least 6 of these variable stars. Look closely around the periphery of the cluster for stars that appear to be twinkling. The images were taken with a 14-inch Meade LX-850 telescope and an SBIG STF 8300M imager.
