Section 10 - Measuring (select objects)

• the angle(s) between the following:
• Betelgeuse and Rigel
•  Castor and Pollux
•  The three stars in the Summer Triangle

 I made the first two measurments on February 1, 2019 at the Edmund G. Kline dark sky observation site of the Denver Astronomical Society.  I used the cross staff.

 The Summer Triangle measurements are going to have to wait until after the snow melts.
