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, EnglandNotes:
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.
