Televue 5x Powermate 1.25 inch (1-1/4 in.)

Experience the exceptional performance of the Tele Vue 5x Powermate 1.25" Image Amplifier, a superior optical tool designed to enhance your viewing and photography experience. This device not only amplifies power but also maintains the eyepiece's eye-relief, providing a comfortable viewing experience. The Tele Vue Powermate is more than just a Barlow lens; it's a four-element parfocal, compact amplifying lens system that improves eyepiece sharpness by slowing down your telescope's f-number. This innovative design also allows for the introduction of compensations for eyepiece aberrations, ensuring a clear and sharp image every time.The Powermate's unique design includes a negative achromatic doublet and a positive "pupil-correcting" doublet. This combination ensures your eyepiece operates with pupil locations as intended by the designer, eliminating mismatch problems. The Powermate is designed to optimally mate its power to your eyepieces, eliminating the need for an additional "interface lens".The Tele Vue 5x Powermate 1.25" Image Amplifier is not just about performance, it's also about convenience. It's designed to be parfocal with Tele Vue's 1-1/4" 90-degree diagonal, often used in Ranger telescopes, adding a level of convenience not previously available with any Barlow.For those using Tele Vue's Paracorr coma corrector with Dobsonian/Newtonian telescopes, the Powermate can be placed into the Paracorr's 1-1/4" adapter, ensuring a seamless viewing experience. This version of the Powermate also accepts the Tele Vue PTR-1250 T-ring Adapter, allowing for close coupling cameras and CCD Imagers. For imaging purposes, the user can simply unscrew the eyepiece holder barrel and screw on the T-Ring Adapter instead. With the Tele Vue 5x Powermate 1.25" Image Amplifier, you're not just getting an optical tool, you're getting a promise of quality, performance, and convenience.

Latest Version Accepets the T-Ring Adapter 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.
