Tele Vue 2x Powermate, 2" Image Amplifier

An essential tool for astrophotography and serious stargazing, the 2x Powermate, 2" Image Amplifier is designed to elevate your celestial viewing experience. This model stands out for its near-parfocal capabilities, setting it apart from the conventional Big Barlow / Interface combination, and allowing for seamless integration with 2" diagonals for an enhanced, uninterrupted observation session.Crafted to deliver exceptional performance, this image amplifier is compatible with every 1-1/2" or 2" eyepiece in our collection, including the renowned 31 Nagler Type 5 eyepiece. Its versatility ensures that astronomers and photographers can achieve sharp, magnified images across a wide range of eyepieces.The build quality of this amplifier is evident in its thoughtful design, featuring a 2" eyepiece holder and a specialized 2"-1-1/2" low-profile adapter. Both are equipped with brass clamp rings, ensuring a secure fit while protecting your eyepieces from scratches and damage during operation.One of the most distinctive features of this 2x Powermate is its adaptability for astrophotography. By simply unscrewing the 2" eyepiece housing, users can attach a special T-ring adapter. This allows for a solid and compact connection to CCD cameras or DSLR camera equipment, making it an invaluable accessory for capturing high-quality images of the night sky.Whether you're an amateur astronomer or a seasoned astrophotographer, the 2x Powermate, 2" Image Amplifier is engineered to provide a superior optical experience, ensuring that every celestial object you observe or capture is presented with clarity and precision.

Vignetting edge field aberrations and pupil movement - all introduced when using Barlows with long focal length eyepieces are minimized. Telecentric operation (field rays leave parallel to optical axis unlike Barlow lenses which diverge rays). This is ideal for Hydrogen-alpha filter use such as with Daystar models. High performance for image amplification CCD or film (some of the finest Earth-based planetary imaging is being done with Powermates). Flexible for visual and imaging with all types of telescopes and eyepieces. Essentially Parfocal and with nearly constant magnification regardless of image distance behind top surface (except 5x model which increases 1x for every 35mm of image distance increase). Higher magnifications are possible with high optical performance compared to "doubling up" Barlows.
