Eta Cassiopeiae (Struve 60)

Sketch Refinement

Above is the cleaned up sketch that was submitted to Sky and Telescope for the September 2006 issue.

August 1, 2005 Observation

Observation Notes:

This was a nice close double. The bright primary was on the southeast side with a deep orange secondary on the northwest side. The color of the primary was hard to tell in contrast with the orange, and was most likely white, but the contrast made it look—get this—Key Lime Pie Green. Hah. My sketch estimates the position angle at about 310° with a separation of 25". The AL double star list values are 307° and 12".
