ABSTRACT:
A simple and inexpensive camera for use in conjunction with a telescope that includes a hollow mounting cylinder that is able to be conveniently slipped into the focus mount of the telescope to align the camera along the optical axis of the instrument and to properly locate the camera thereupon. In assembly, the cylinder depends downwardly from the bottom of the camera housing and conducts the telescopic image into an exposure aperture passing vertically through the housing. A film slit passes horizontally through both the housing and the aperture to provide a guideway for positioning film over the aperture within the image plane of the telescope. A slide containing a ground optical element is slidably supported in the aperture whereby the element is movable into a first position within the image plane of the telescope to present a light image of an observed body thereupon, and into a second position wherein the bottom surface of the element is coextensively aligned with the top wall of the film slit.
