ZWO 1.25" / T2 (M42x0.75) photographic nosepiece adapter (ZWO, SKU: ZWO T-Mount) is a mechanical adapter that allows a camera or another component with a female T2 thread to be installed in a standard 1.25" eyepiece focuser. The nosepiece is inserted into the telescope focuser in the same way as an eyepiece, while the external T2 thread connects to the camera or a suitable photographic adapter ring. The adapter is intended primarily for prime-focus photography through a telescope.
