What's Happening?
Leslie Peltier, renowned as one of the world's greatest amateur astronomers, made significant contributions to the field by discovering numerous comets and recording over 132,000 variable star observations. His autobiography, 'Starlight Nights,' recounts his passion for astronomy and his observations through a 12-inch refractor telescope. A particular observation described in his book involved two pulsating stars in Cassiopeia, referred to as 'two tiny diamonds.' Amateur astronomer Doug Zubenel, inspired by Peltier's work, embarked on a quest to identify these stars. By examining Peltier's digitized variable star observations, Zubenel identified CE Cas A and CE Cas B as the likely candidates. These stars are classical pulsating Cepheid variables located in the open cluster NGC 7790, visible in the fall, matching the timeframe of Peltier's observations.
