Newtonian Position Angle Chart

[James4]

If like me, you are new to double star observing, this chart will help you make simple notes at the scope and calculate the real PA later. The idea is that when observing, you simply note your focuser position and clock position of a double star pair. Later consult the chart and convert what you saw to the real Position Angle of the double star.

This is what happens after reading about Sirius B on Stargazers Lounge and having to much access to Photoshop!
