Celestron NexYZ 3-Axis Universal Smartphone Adapter
NexYZ will also attach to microscopes with the addition of the included microscope adapter ring, which takes the usable diameter down to 25 mm, the size of a standard microscope eyepiece. The Celestron NEXYZ 3-Axis Universal Smartphone Adapter fits any eyepiece from 30 mm to 60 mm in diameter including telescopes with 1. A strong spring and a threaded twist lock provide a two-level strong and secure grip on the optical instrument’s eyepiece so you can image with confidence. The process from start to finsh only takes about 30 seconds, including the time it takes to insert the phone into NexYZ, attach NexYZ to an eyepiece, start the camera app, and center the camera over the eyepiece using the knobs.
