Bill Pellerin – Observing Variable Stars

Bill will talk about how to observe, both visually and with a CCD camera, variable stars and how to report the data you gather to the AAVSO. The goal of the presentation is to provide the NHAC members with enough information to begin taking variable star data of their own.
