Beta Orionis (Rigel / Struve 668)
October 10, 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:
Rigel is incredibly bright, with diffraction spikes reaching to the edge of the view. The companion star appears close and directly south of Rigel. The seeing is pretty crummy, but the companion still shows up. Fortunately, the spider vanes were turned to the perfect angle to let it show between them.
