The TeleVue Powermate line brings magnification experiences to your equipment that can take on an almost invisible extension feel! The TeleVue 2.0x 2" Powermate embodies this experience perfectly with high quality optics, near parfocal performance, and importantly no modification of your eye relief. This allows you to double the magnification of your view with minimal additional aberrations or distortions compared to most Barlows, while looking through your eyepiece just as you would with no accessory between your viewport into the night sky and focuser/ diagonal, and requiring minimal refocusing when using the this accessory. This makes the Powermate almost seem to disappear, leaving you to enjoy a more up-close-and-personal experience with the wonders above. The elegant performance of this multi-coated optical design is 100% quality checked at f/4 through TeleVue's QC program, helping ensure that your experience meets their standard of excellence on day one. This attention to detail and high standard for excellence extends to the physical design of the TeleVue 2.0x 2" Powermate as well; with an superbly finished black housing and 2" chrome barrel, M48 filter threaded barrel, brass compression ring 2" eyepiece holder, and 2" to 1.25" adapter.
An Elegant Extension of Your Equipment
The TeleVue 2.0x 2" Powermate brings high quality magnification and parfocal performance to your visual or imaging instruments. Read on to discover how this magnification multiplier will transform your experience!
Superb Magnification Multiplication
Typical
magnification multipliers—Barlows—can introduce vignetting, edge
field aberrations and longer eye relief alongside your closer look into the
universe. This is a consequence of the diverging light rays that leave a
traditional Barlow lens, and led TeleVue to create the Powermate design to
give users a "compact, high power, fully corrected image amplifier." With a
4-element design consisting of a negative doublet and positive
"pupil-correcting" doublet,
light rays exit the PowerMate in their original direction and give you
what TeleVue describes as a "pure magnification increase."
This telecentric design minimizes possible vingetting and keeps your
eyepiece's eye relief at the same distance as it would be unassisted, an
incredibly helpful feature for keeping long eye relief equipment from being
pushed out to uncomfortable distances. This entry in the Powermate series
doubles your magnification, providing a noticeable zoom that will help you
bring the lunar surface, planets, and other astronomical wonders closer!
Nearly Parfocal
The TeleVue 2.0x 2" Powermate features
a nearly parfocal design to make quickly magnifying your view simple! When
used with a 2" star diagonal this design focuses your eyepiece with the
focuser set to almost the same position with and without the Powermate. This
means increasing your magnification can be done nearly effortlessly,
compared to typical Barlow solutions which require more significant focus
adjustment.
Adaptable to Imaging
The Powermate line is for more
than just visual use! This 2x 2" Powermate provides virtually the same
magnification increase regardless of whether the camera sensor is 0-100 mm
away from the top of the compression fitting, giving you flexibility in
installing your dedicated astro camera in the 1.25" or 2" holder. This isn't
just for dedicated cameras either—as the 2" eyepiece housing can be
unthreaded and the
Tele Vue T-Ring Adapter for 2" 2x Powermate
(sold separately) installed for an M42/ T-thread connection for DSLR and
mirrorless T-rings or some dedicated astro cameras with the nosepiece
detached!
Impeccable Quality
Attention to detail, high quality,
excellent optical designs, and minimalist yet sleek looks are hallmarks of
the TeleVue name, and the TeleVue 2.0x 2" Powermate is no exception. The
optics feature multi-coating to support the superb performance of the
optical design, and go through TeleVue's 100% QC program at f/4 to ensure
your focal extender meets their high standards. These are housed in a finely
finished black metal housing with high contrast lettering that makes
identifying your gear in the dark easier; with a 2" chrome barrel for your
2" diagonal or focuser. Holding your eyepieces securely without the marring
effect simple thumbscrew holders can impart, is a 2" brass compression ring.
A 2" to 1.25" adapter is included for connecting your 1.25" visual or
imaging gear, as well as M48 filter threads on the 2" barrel that will allow
you to enhance your view with 2" filters!
