Eta Persei (Struve 307)

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.

Observation Notes:

The primary star was a brilliant orange, with a blue-white secondary that picked up a hint of violet from the contrast. The diffraction spikes of the primary ran right over the secondary. I estimated PA at 295° and separation at 45". Listed values from the AL double star list are 300° and 28.3".
