Star fields and clusters.
Here is a photometric image of R Crb, a very unusual variable star. It 'usually' shines at 6th magnitude, but since 2007 it has been considerably less bright. Last night (4/20/12) it was at 12.48. Taken with a Atik 320E and a V band photometric filter. Five minute exposure. Processed using VPHOT online software via the AAVSO.
