565 Spring Clamp
Hold-down clamp for spherical mounting system
The modified “U” shape of the model 565 spring clamp is designed to hold a 521-B spherical mount in a 560‑2 cup mount. The 521-B may in turn hold a target or an alignment telescope’s objective end. Two small upturned clasps at the bottom of the spring clamp seat into recesses on the cup mount. A thumbscrew provides sufficient force to clamp a spherical adapter in to the cup mount.
