Note: Different camera models have different appearance of T-ring, Subject to receipt of goods. if you mind, please do not buy. Light shooting and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3mm. Use Demo The adapter's 1.25 inch nosepiece slides into the telescope's eyepiece holder just like an eyepiece. This Variable Universal Camera Adapter is composed of two detachable parts: a prime-focus adapter (or "T-adapter") for prime-focus photography, and a fixed-length or variable extension tube for eyepiece-projection photography. A thumbscrew in the extension tube holds the telescope eyepiece in place. This combination of prime-focus and eyepiece-projection camera adapter has a sliding barrel design that allows variable projection distances. This allows for slight changes in magnification without swapping telescope eyepieces when performing eyepiece-projection photography. Fits reflector and refractor telescopes with 1.25 inch eyepiece holders. The Variable Projection Camera Adapter allows for a continuous range of projection magnifications during eyepiece-projection photography for telescopes with a 1.25 inch focuser The machined sliding-cell assembly can be fixed at any position along its length and is held in position via a thumbscrew. The resulting effective focal ratio is then determined by the sliding adjustment and eyepiece used. A T-ring specific to your D/SLR camera is required to connect your camera to this adapter (Please select the correct T ring according to your camera model). Tips: For eyepiece projection photography, the maximum outer diameter of the eyepiece is 37mm.
