NGC 2682 (M67) is one of the oldest open clusters in the Milky Way (abt. 4 billion years), and has many stars similar to the sun.  It also has numerous red giants.  It has a yellowish cast due to a lack of bright, young stars.  A total of 1 hour, 20 minutes of 3 minute exposures were taken at -8 degrees Celsius, at an elevation of 8300 ft. We used a Meade 10" F/4 Schmidt Newtonian on Losmandy G-11 Mount.  Cooled Canon 400D with IR filter removed.  Processed in Nebulosity and Photobrush.  Dark and flat frames applied.
