\nOctober 17, 2006: To help provide a consistent style for my double star sketches, the above sketch is a digital update to the original sketch.<\/i>
\n<\/p>\n

Observation Notes:<\/b><\/p>\n

This pair exhibited beautiful color at low power. The brighter southern star was yellow-orange, while the norther was blue. It was a nice contrast. I guessed a separation of 75″–it’s actually 45″. Man I need to work on that. The position angle in the sketch of approximately 350\u00c2\u00b0 matches the AL list measurement on the dot. The faintest star I plotted in the sketch was mag 12.7 GSC 0264701827.<\/p>\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n
