M 52 discovered by Messier in 1774 is shown here in an unguided co-added 3x5 minutes Stromgren y filtered exposures. This image is part of a battery of tests I am excercising on the observatory in preparation for a a new science run that will use Stromgren filters for stellar and luminosity classification. I am glad to report that the Stromgren y filter which peaks exactly where the Johnson V filter does, is performing well in initial tests. It is also an opportuinity for you to glimpse at a cluster with a controversial history about its true distance. Reports vary considerably in the literature and mostly attributed to interstellar extinction.
