Tele Vue 2x Powermate – PMT-2200

The Tele Vue 2x Powermate is a premium image amplifier designed for serious visual observers and astrophotographers alike. Compatible with all 2" eyepieces and accessories, it also includes a 1.25" adapter for added versatility.

• • Key Features:
    • Advanced Optical Design: Utilizes a four-element system combining a negative and positive doublet to deliver superior optical correction and consistent performance across the field of view.
    • Enhanced Magnification: Offers high magnification capability with excellent optical quality—significantly better than stacking traditional Barlow lenses.
    • Visual & Imaging Ready: Ideal for both visual use and imaging, including CCD and film photography. Delivers exceptional results in planetary and lunar imaging.
    • Camera Compatibility: Accepts Tele Vue’s optional T-Ring Adapter (PTR-2200), allowing close-coupled connection to DSLR and CCD cameras.
    • Perfect for Narrowband Filters: Features telecentric optics, making it an excellent match for Hydrogen-alpha solar filters, such as those from Daystar Instruments.
  • Why Choose a Powermate Over a Barlow?
    • Minimized Optical Aberrations: Virtually eliminates vignetting, field curvature, and pupil shift often encountered with traditional Barlow lenses.
    • Telecentric Operation: Unlike Barlows, which diverge light rays, the Powermate keeps rays parallel to the optical axis—critical for narrowband and solar imaging applications.
    • Consistent Magnification: Offers nearly constant magnification regardless of distance behind the top surface—ideal for imaging setups (note: the 5x model is an exception).
    • Nearly Parfocal: Most Powermates, including this 2x model, are essentially parfocal in standard star diagonal configurations, requiring minimal refocusing.
    • Build Quality: Includes full multi-coatings, filter threads, captive thumbscrews, and safety undercuts for secure and reliable use.

Imaging with the Powermate:

Powermates are a top choice for planetary imagers seeking to achieve higher image scales without introducing optical artifacts. The 2x Powermate delivers crisp, contrast-rich results, even when used with high-resolution sensors. It supports direct camera mounting with optional T-Ring adapters, enabling prime focus astrophotography with ease.

For example, using a 24mm Panoptic eyepiece with the 2x Powermate effectively transforms it into a 12mm focal length eyepiece, maintaining clarity and eye relief.

 

Of course! Here's the polished and reworded version of that section again:

Using Powermates™ for Astrophotography & Visual Excellence

For astrophotographers, Powermates™ provide consistent and predictable magnification based on the distance from the Powermate’s top surface to the imaging plane (CCD or film). The four available models—2x, 2.5x, 4x, and 5x—offer a versatile range of imaging options.

1.25" Powermates™ – 2.5x & 5x

These compact models extend less than 3" from the focuser and are parfocal in all 1.25" star diagonals and prisms, making them an excellent upgrade over standard Barlows—especially for refractors like the Tele Vue-60.

• The 5x Powermate™ provides up to 7.7x magnification, offering a powerful yet high-quality alternative to eyepiece projection.
• Perfect for long-focus CCD and film imaging, and for slowing down the focal ratio in Hydrogen-alpha solar observing.
• Accepts 1.25" threaded filters and maintains a lightweight, compact form for easy integration with your setup.

2" Powermates™ – 2x & 4x

Optimized for 2" diagonals, these Powermates™ offer superior optical performance and convenience compared to traditional 2" Barlows. They are nearly parfocal, requiring minimal refocus, and are fully threaded for 48mm filters.

• Delivers excellent results with all Tele Vue 1.25" and 2" eyepieces, including the 31mm Nagler Type 5.
• Both the 2" eyepiece holder and included flat-top adapter feature brass compression rings for secure, non-marring grip.
• The eyepiece housing can be removed, allowing you to attach a Tele Vue T-Ring Adapter directly for solid, compact camera attachment.

Example: Use the 4x Powermate™ with a 35mm Panoptic and enjoy an effective 8.8mm focal length while retaining the original 25mm of eye relief—and no Panoptic-Barlow Interface is required.

• Fits fully into standard 2" star diagonals, with less refocusing needed compared to traditional 2" Barlows.

Special Note for Dobsonian & Newtonian Users

When using a Tele Vue Paracorr coma corrector:

• Insert 2.5x or 5x Powermates™ (1.25") into the Paracorr’s 1.25" adapter, placing them between the Paracorr and the eyepiece.
• Insert 2x or 4x Powermates™ (2") directly into the focuser, followed by the Paracorr into the Powermate.
