We have observed the central stars of two planetary nebulae, Abell 65 and Hubble 12, both of which are claimed to be close binary systems. We are looking at the differential photometry from these systems in hopes to find or reproduce evidence of variability caused by close binaries. Binary interaction in a planetary nebula is a possible source of the structure of bi-polar or butterfly PNe. We confirm that one of the two systems, Abell 65, is a binary with a period very close to one day and exhibits irradiation or ellipsoidal variation but is not eclipsing. With Hubble 12, which was claimed to be an eclipsing binary system with an irradiation effect, we found no clear variability due to a binary system and recommend that it be removed from the list of known binary central stars.
