October 12, 2006: To help provide a consistent style for my double star sketches, the above sketch is a digital update to the original sketch.
A neat multiple star area. There was a triple star at center with a blue component on the west side. The northeast component almost looked orangeish by comparison, but it's really white. Another double is on the west edge of the view.
