Rigel and BetelgeuseOn february 8th 2011 I made sketches of Rigel and Betelgeuse. Both stars were observed through the Orion Optics 300mm. The sketch of Rigel represents a field of view of 52' and a magnification of 94x (17mm Nagler Type 4). The sketch of Betelgeuse represents a field of view of 37' and a magnification of 133x (12mm Nagler Type 4). South is up and east is to the left.
