TeleVue 5x Powermate is a compact, high power, fully corrected image amplifier.  TeleVue Powermate line consists of a negative doublet plus a positive "pupil-correcting" doublet.  Its 4-element system provides the magnifying function of a TeleVue Barlow without its limitations by restoring the field rays back to their original direction, as if the TeleVue Powermate was not there.  The result is a pure magnification increase.

The TeleVue 5x Powermate features include blass clamp ring and coptive screw.  It accepts TeleVue T-Ring Adapter.  It has a fresh approach to multiplying power, and has big power in a small size.  It includes fully corrected field.  Ideal for use with long focal length eyepieces.  Not threaded for filters.

Unique Benefits and Applications for Powermates

Vignetting, edge field aberrations and pupil movement - all introduced when using Barlows with long focal length eyepieces, are minimised.

Telecentric operation (field rays leave parallel to optical axis, unlike Barlow lenses which diverge rays). This is ideal for Hydrogen-alpha filter use.

  1. High performance for image amplification, CCD or film (some of the finest Earth-based planetary imaging is being done with Powermates.
  2. 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.
  3. Higher magnifications are possible with high optical performance compared to “doubling up” Barlows.
  4. All will reach parfocal point in star diagonals.

In addition to full multi-coating, Powermates include other Tele Vue special touches such as safety undercuts where practical on the chrome barrel and captive lock screws that can’t fall out, and filter threads. Our 100% QC program at f/4 insures that Powermates will add dramatic power (and NOTHING ELSE) to your favorite eyepieces.

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 -- like in prime focus photography.

TeleVue 1.25" 5x Powermate stand less than 3" out of your focuser and takes 1¼" threaded filters. They are parfocal in ALL 1¼" diagonals and prisms. For this reason, they are highly recommended over standard Barlows for 1¼" diagonals and refractors such as the Tele Vue-60.

Note for Dobsonian/Newtonian Owners

When using Tele Vue’s Paracorr coma corrector, the 2.5x Powermate should be inserted into the Paracorr’s 1-1/4” adapter (i.e., between the Paracorr and the eyepiece).
