Sample observations of eclipsing variables made in Berlin, Germany, using a 25-cm Schmidt-Cassegrain telescope and an electric photometer with an EMI 9781B tube and UBV filters are presented, with the aim of demonstrating the usefulness and attainable precision of amateur observations of these stars. The photometer calibration procedure is outlined, and light curves of XY Leo, WW CnC, SAO 072799, BM Cas, V695 Gyg, Zeta And, RX Cas, and the 'c' object in Lynx (discovered by Frank in January, 1983) are discussed. The latter is found in preliminary observations to have a period of 0.197 day (assuming it is an eclipsing binary), and the fact that its B minimum occurs about 4 min later than its V minimum suggests that it may be a Delta-Scuti-type binary containing an A star. It is pointed out that a large number of unmeasured variable stars are of sufficient brightness for amateur photometric observations.
