The Moon, Gibbous Phase


Date: 17th Jan 1989
Time: 18:27 UT
Exposure: 1/4 sec @ f32
Equipment: 800mm FL f8 telephoto lens (Tokina) plus a 2x teleconverter
           (lens aperture set to f16) This gave a focal length of 1600mm.
Film: Kodak Ektachrome 100HC
Site: Prestwich, Manchester, England


Notes:

The lens was mounted on a tripod with a small drive. The exposure 
was made with the aid of a black piece of card held over the lens.
When the shutter was pressed (cable release) the card was moved
away to make the exposure then the card replaced over the lens to
stop the exposure. The above was necessary as the opening of the
shutter caused the lens to shake.
