This is an image of a thin crescent moon, showing the illumination of the dark area of the moon by earthshine. The illumination provided by the earthshine was readily apparent to the naked eye. The image below depicts the moon at the same time using a faster shutter speed that does not show the earthshine. On June 7, 2005, I took an image of a 29 hour old Moon near Venus in the evening sky, which displayed a very thin crescent in the evening twilight sky.
These CCD images were taken with an ST-8E using a Takahashi Epsilon 250 telescope at f3.4. The CCD was binned 3x3 and a blue filter was used. This image was taken at the Sunglow Ranch, located in southeastern Arizona.
