YSO CCD getting started

We are gearing up to do photometry on some of the stars on the YSO list:

V682 Aql, V686 Aql, DU Cep, V357 Cep, C730 Cep, V353 Lac, and/or XX Sct.

These will be CCD observations using a C14 with an Apogee U47 and Optec BVRI filters.

Questions: as there is very little comp star data available, what do you suggest in terms of filters?  What filters have been used in the past to study these stars, and why?  Are there specific questions about these stars--individually--will be addressed?

For each imaging session, should we average a series of single-filter exposures?

thanks...
