80mm Series 5000 ED APO Optical Tube Assemblies

For crisp wide field observing and imaging, nothing can beat a true triple-element apochromatic refractor (APO). This is especially true in astrophotography, where APOs have produced some of the most beautiful images of the heavens ever taken from earth. But not all APOs are created equal. Today’s market is filled with semi-APOs (with two lenses instead of three) that don’t bring all the colors to focus in the refractor. Thanks to a two-year design process and a triple objective lens made from the highest quality ED (extra-low dispersion) glass, Meade Series 5000 ED APO Triplets are virtually free of chromatic aberration (color fringing). This means they outperform the most expensive semi-APOs at a fraction of the cost. Expert observers will be delighted by the total absence of color fringing and the scope’s textbook-perfect pinpoint star images. Even beginners will notice the breathtaking high contrast and resolution of a Series 5000 APO. One astronomer commented that the Series 5000 APO “kicked butt on my semi-APO that cost twice as much.” The scope is available as a standalone OTA, or as a package with our new Series 5000 2” enhanced diagonal and an aluminum carrying case.

TeleVue 102

At Tele Vue, we always try to provide good value in addition to great optical performance. With the Tele Vue-102 we offer the amateur a simpler, less expensive, 4” refractor which retains Tele Vue’s core values; outstanding optical performance and superb mechanical quality.

TeleVue 102i

Televue’s newest model APO refractor (102mm aperture, 880mm focal length, f/8.6) is designed to permit lower power, wider field binocular viewing - all in a more compact form. The Tele Vue-102i sports the same overall length as the Tele Vue NP-101, making it easier to transport. It will fit in the NP-101’s soft carry bag (product code NPB-1001).

TeleVue 60

High Performance 2.4” APO doublet, 360mm f/6 objective, OTA only 10”-long - includes 2-stage 1¼” focuser with quick-focus drawtube plus fine-focus helical. Exquisitely machined and anodized all-metal construction with sliding captive dew shield.

TeleVue 76

The Tele Vue-76 combines Pronto’s compact size with the APO optical performance of the Tele Vue-85. The
expansive 5.5° rich-field drizzles your view with delicate jewel-like stars, while the APO performance
of the new Nagler designed, multi-coated 2-element objective and 2” Everbrite diagonal produce natural
stellar and planetary color rendition even at the highest useful powers. Small size and lighter weight
permit use of lighter-duty tripods for easy field carrying and transportation. The padded shoulder bag
provides protection and room for the scope and six eyepieces. If your interests crossover from
astronomical to spotting or birding, and you demand the ultimate in portable performance the Tele
Vue-76 is always waiting to deliver. 

TeleVue 85

The Tele Vue-85’s mix of aperture and small physical size makes it a wonderful ”go anywhere, do
anything,” crossover instrument-with Tele Vue quality, of course. With APO performance and airline
portability, the Tele Vue-85 has been delighting astronomy and birding enthusiasts and reviewers alike.
”Eye-popping performance that raises the standard of excellence for highly portable instruments.”
Evaluation of double-stars, lunar detail, deep sky and photography were reported in Sky and Telescope
as: ”Truly awesome! ...Incredible!...the view almost blew me off my chair!...” The conclusion, ”...an
extremely powerful, compact instrument capable of delivering stunning images of the universe.”

A70Lf 70mm Achromatic Refractor Telescopes

The A70Lf, although inexpensive, is not a toy telescope. Many amateurs begin with and enjoy countless
hours under the stars with this instrument It has the same quality glass and exacting workmanship that
goes into our much larger instruments.

With this size aperture you will, as I did, be on your way to discovering the craters and mountains on
our moon, the rings around Saturn and the storms on Jupiter. With a star chart you’ll find beautiful
double stars of varying colors, and on moonless nights, you will see the Andromeda Galaxy, The Orion
Nebula and hundreds of other Deep Sky objects.

A80Mf 80mm Achromatic Refractor Telescopes

If you are looking to start out with something a little larger than a beginner scope or need a better
finder scope for your large telescope, the A80Mf is the one to buy. Although it is just 10mm larger
than its smaller cousin the A70Lf, this extra aperture will reveal more detail in solar system objects
and the deep sky alike.

I find myself using the 80mm size for terrestrial viewing of ships on the ocean or whale watching. With
an optional sun projection accessory I have viewed sun spots projected onto a white surface. (Of course
NEVER look at the sun directly). The A80MfLf, although inexpensive is not a toy telescope. It has the
same quality glass and exacting workmanship that goes into our much larger instruments.

A80SS 80mm Achromatic Refractor Telescopes

If you are in the mind to own a quality telescope that is designed for travel, there is nothing better
than the A80SS. It’s our newest short focal length 80mm refractor. This is a great cross-over
astronomical and terrestrial scope.

The A80SS is extremely portable. It is small enough to be mounted on a photo tripod for the casual
astronomical / terrestrial observer with enough aperture for excellent deep sky viewing. The optical
tube comes standard with our red dot finder, 2” focuser, flip mirror diagonal and dovetail tube plate
for quick and easy mounting.

At less than 11” with dew shield flipped, the Vixen A80SS is the ultimate grab-n-go travel scope! 

ED100Sf 100mm ED Apochromatic Refractor Telescopes

The ED 100Sf is now available for the first time in the US. It is the big brother of our best selling
ED80Sf. This APO refractor features high-grade glass and quality components.

Coupled with a medium f/9.0 focal ratio, the ED "S" series provide a sharp, color-free image of high
contrast. For the astronomer that wants the best value f or the dollar in a 4” APO, this is the one to
get.

ED103S 103mm ED Apochromatic Refractor Telescopes
