Our quality Cell Phone adapters will fit many Telescope or Microscope eyepieces with an outside diameter of 1.5" or less. We also offer an upgrade to fit eyepieces with an outside diameter of up to 2". Several versions to fit many popular phone models directly.. without messing around with adjustable phone holders. This adapter uses our popular Uni-T universal eyepiece adapter for quick easy installation. In addition the Uni-T can be unscrewed to reveal a standard Female "T" thread (42mm) for connection to many optical devices. The case is made of plastic to avoid marring your phone, the Eyepiece & T-Thread adapter are CNC machined from aluminum with a durable black anodized finish. The Nylon thumbscrews secure and align the adapter without marring your eyepiece. After initial setup and alignment simply loosen the 2 indicated thumbscrews and slide the unit off the eyepiece, subsequent installations on the same eyepiece will be even quicker and self-centering with just a twist of the same 2 screws. This is an "Afocal" adapter and shoots directly through an eyepiece. See the app store for specialized software (not required) for this purpose. See last item below for 2" Upgrade.
Note: The Eyepiece must have a cylindrical shaped upper
barrel of 1.5" or less for the standard adapter, or 2" for the optional adapter.
