Moon_80MM_F5_20120831_H-alpha-_HomCavObs

The full moon of August 31, 2012, a modern day 'blue moon' - the second full moon in a given month. Occuring on average once every 2.66 years. It of course did not appear blue this particular night but rather it's normal beautiful golden color when rising (and here in B&W due to the use of a monochrome CCD). Forest fires and volcanic eruptions only occasionally cause the moon to actually appear blue, hence the saying "one in a blue moon". Image taken on 08/31/2012 by Jay Edwards at the HomCav Observatory using an Orion 80MM carbon-fiber tube apochromatic refractor, Televue 0.8x field flattener / focal reducer, narrowband h-apha filter and MX-716 CCD.
