Schmidt-Cassegrain 8" Reflex Film Camera at the prime focus. Film: Kodak Gold 200
The picture is the result of a digital process. Two images were taken at the moon; the first when it was partially inside in the penumbra cone of the earth and the second when the moon was totally out of the earth shadow. The exposition of both the pictures is the same (1/1000 sec) A blend (subtraction) of the two inverted images gave me this result on which the light blue colored part at the right of the moon appears the penumbra. Hard to obtain with the traditional imaging techniques.
