Use the Novagrade T-Mount Adapter to mount your camera directly to any spotting scope, telescope, or binocular. The adapter fits on the camera-specific T-ring, and to work properly the ISO setting and shutter speed will need to be manually set. The adapter has a clear glass filter to protect against water or dust from entering the camera body. A polymer compression ring fits over eyepieces with outside diameters from 1.5 to 2.4" (39 to 60.75mm) and the twist-lock mechanism ensures a perfectly centered image as well as a secure, mar-free interface to the optic. This digiscoping adapter is made in the USA from a lightweight and durable aluminum alloy with a corrosion and scratch-resistant anodized finish.
