To use, attach the camera to the C-thread of this adapter. Then slide the 2" barrel into your 2" telescope focuser and you are ready to shoot. Made of black anodized aluminum. Internally grooved to reduce stray light reflection for maximum contrast. Features a tapered barrel for added security while clamping.
