October 18, 2006: To help provide a consistent style for my double star sketches, the above sketch is a digital update to the original sketch.
The seeing was poor in this part of the sky and the color of the stars hard to determine. If anything, the primary was pale yellow, and the secondary blueish. I estimated PA at 70Â° and a separation of 18″. Listed values from the AL double star list are 85Â° and 12.1″. I didn’t do so hot on the PA there.
