Bill Burnyeat (l) gets help from Tahirih Bidanjiri to demonstrate how a little star orbiting around a big star can cause the light from them to vary.
Burnyeat was the presenter during the annual Star Gazing Festival, which was held this year on Aug. 6 at Edgewood Blue (Trevor Goward's home in Upper Clearwater).
About three dozen people attended and, despite an overcast sky, enjoyed Burnyeat's presentation.
Bidanjiri is from Victoria and was visiting her grandparents, Ron and Shauna Plamondon of Clearwater.
