Iota Orionis (Struve 752)

| 2 Comments


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:

Main component is quite bright and blue. The other two members are to the southeast and east. The closest one is much dimmer than the primary, but is easy to split.The third star almost hides in the diffraction spikes.
