Abstract Using a CCD Camera with a Kodak 401E/L
chip and a Meade LX200 Schmidt Cassegrain telescope, we confirmed variability
and determined preliminary light elements of three stars listed in the NSV Catalogue:
NSV 11924, NSV 12971, and NSV 12978. The first two are pulsating variables of
the RR Lyr type. The third one is an eclipsing binary of the EW sub-class. For
other two stars (NSV 10998 and NSV 12965) no variability was detected.
