Tele Vue 4x Powermate T-Ring Adapter

TeleVue's 4x Powermate T-Ring adapter allows you to unscrew the standard eyepiece fitting of your powermate. With the T-ring adapter installed you have a secure and much more compact connection between your camera and 4x Powermate. It also guarantees perfect camera sensor alignment, a very important consideration when imaging with such high amplification.

Imaging the Solar System with Powermates™

Some of the finest Solar System images have been made with Powermates™. Used singly or stacked, Powermates™ help any scope achieve the long focal-length required to image details on Solar System bodies. The increased image scale allows for imaging without an intervening eyepiece. Powermate T-Ring Adapters fit on the Powermate lens assemblies to allow attachment of your camera's T-Ring or other T-threaded imaging accessory.
