Abstract
An adapter for operatively coupling a reflex camera having a preprogrammed automatic cycle of operation to an optical instrument such as a microscope or telescope. The adapter includes mechanisms which permit the operator to selectively modify the preprogrammed cycle of operation for the purpose of making extended time exposures or allowing vibrations induced by the movement of a camera reflex member to subside prior to initiating film exposure.
