Sigma Cassiopeiae (Struve 3049)


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:

This is the closest AL Double I've observed so far. Both stars were white. The secondary appeared to sit at 330° PA, and a distance of about 2.5 diffraction rings from the primary...so maybe that's about 2.5"? Listed values from the AL double star list are 326° and 3".
