I have been into Astronomy for many years, actually since 12, I have taken many Astrographs started with film using various cameras and telephoto lens and such. This photo of the crescent Moon was taken with Olympus OM1 Body with 200 ektachrome film and a 2000 mm Celestron C-8 casssegrain lens. I try to find and photograph the earliest day old Moon, although it is not always easy..
