We present results of BVRI photometric observations of the delta Scuti variable QS Geminorum and the nearby eclipsing binary GSC 01342-01261. Analysis of recent observations, combined with data obtained by Hintz. et. al. (2000) allow improved period estimates for these two variables. We find a period of 0.1320 cycles/day for QS Gem, with significant secondary modes of oscillation. For the eclipsing variable, we find a period of 0.6992 cycles/day, approximately half the previous estimate (Carroll et. al.). We also confirm the classification as an Algol binary.
