Sketch Refinement

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


August 2, 2005 Observation

Observation Notes:

This beautiful, close double star had a bright yellow primary and deep blue secondary. The contrast almost made the secondary look violet. My sketch suggests a position angle of 55° and a separation of 35". Actual values from the AL double star list are 63° and 9.8".
