For photography of the moon, planets and stars through a telescope using 2-inch eyepieces, this Saxon variable-projection camera adapter is a versatile choice. It incorporates a machined, sliding mechanism that permits variable projection distances during eyepiece-projection photography. And this eliminates the need to switch to a higher-power eyepiece for additional enlargement. Two thumbscrews lock the sliding cell in position at the desired projection distance, and a third screw locks the eyepiece in position. A separable, thread-in unit also permits prime-focus photography.
All parts are of machined aluminum and brass. The 2-inch barrel is threaded for filters. Use with a T-Mount, ordered separately, for your brand of 35mm camera body.
