If you are speaking of some objects in the context of variable stars, the use of "variable star designations" (GCVS, NSV) is more preferred than that of general catalogs. Otherwise, you might better refer to general catalogs (HD, BD - Durchmusterung, GSC and others); it would be probably preferred to call a star's name with a Durchmusterung number rather than the NSV number when you are speaking of a steller occultation.
