Rules for double star observing program
While this is intended to be a novice program, all FBAC members are invited to participate.
No Go-To and no digital setting circles. Analog setting circles may be used.
Record your observations on a log sheet. Acceptable log sheets should include the following: Object, Date, Time, Instrument used, magnification, an estimate of seeing, and a simple sketch of the star system. The sketch should indicate North and either East or West.
Submit your completed list of observations for verification.
An FBAC Double Star Award certificate will be awarded for successful completion of the program.
