The OnAxisLock2 50.8 mm accessory mount secures an eyepiece, a right-angle prism, or a compatible slip-on camera by manually rotating its outer ring. It uses two compression rings instead of individual screws.
Its telescope-side interface is: an M56 thread on a 2-inch Esatto or 2-inch Arco mount. The stated optical thickness is 26 mm. The diameter of the accessory received is 50.8 mm; this dimension should be distinguished from that of the connection on the eyepiece holder side.
The two rings distribute the clamping force evenly around the circumference of the focuser. This design is intended to minimize pressure marks and maintain the alignment of the accessory within the optical train, whether for observation or photography. It does not replace the tilt adjustment of a sensor if another component of the mount is misaligned.
The external knurling can be operated without tools, even while wearing gloves. This product description applies only to the accessory mount; cameras, eyepieces, and right-angle prisms are examples of its uses. No maximum load capacity is specified.
