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.”
