NSV 2798 = GSC 1325-1771, at 6 03 11.9 +22 03 30 (2000). As far as I
know there is no broadband photometry (BVRI) of any kind in the region of
this star. You might consider using some of the brighter nearby Tycho-2
stars for a reasonable zero-point calibration for B and V. Be sure to
correct the Tycho data to the standard system, and avoid stars with errors
of 0.03 mag. in either B or V. Another option is to use stars in the $B(Bearbopen(B $BclusteMessie35(B $Bforeference.(B $BTheris(B $Brecent(B $BUBVI(B $Bphotometry(B
