Tele vue TV85 APO Telescope - Evergreen OTA

• Televue TV85 APO Telescope - Evergreen The Televue TV85 telescope is a superb travel scope, measuring only 21.5" (546mm) in length and weighing 8 lbs. (3.6 kg). 23.6" (600mm) focal length combined with 3.35" (85mm) aperture produces an f/7 refractor capable of a limiting stellar magnitude of 12.1 with a superior 1.36 arc seconds of resolution over a 4.4° field.
• The Televue TV85 refractor combines true apochromatic doublet lens performance with special dispersion low chromatic glass to produce stunning image sharpness and color.
• The Televue TV85 green telescope OTA includes a screw-in dust cap, retractable dew shield  and custom soft carrying case.
• Comes complete with specially manufactured 10:1 dual speed focuser for exceptional smoothness and focus sensitivity.

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."

The Better View Desired website reviewer summed up the Tele Vue "experience" when he said he would choose the Tele Vue-85, "...to really enjoy the incredible beauty of the living birds... And, even now, every time I look at a bird through one of the exceptional conventional spotting scopes, I'll be thinking: 'I wonder what this would look like through the Tele Vue-85? I wonder what this bird really looks like?'" Yes, pure enjoyment of nature's beauty without awareness of a thing in between.

"Dawes' limit states that an 85-mm objective should resolve double stars separated by as little as 1.3 arcseconds. My first double-star test was Gamma Leonis. This beautiful pair has a 4.4-arcsecond separation and components of magnitude 2.2 and 3.5. It is considered easy for small telescopes. I centered the star using a 35-mm Panoptic eyepiece, which yielded a tack-sharp 17x image. Switching to a 7-mm Nagler upped the magnification to 85x, which easily split the double. I then tried the 15-mm Panoptic and 5x Powermate to obtain 200x. The stars were sharp Airy disks surrounded by extremely clean concentric diffraction rings. A wonderful view! My next target was the 4th-magnitude double Gamma Virginis, with a 1.7-arcsecond separation. The stars were easily split at 200x. Pushing further, I tried the 7-mm Nagler with the Powermate for 428x. The stars appeared sharp and clean with perfect Airy disks surrounded by concentric diffraction rings. The only image degradation was due to the seeing, not the optics. Truly awesome! I had the same visual impression, both at 200x and 428x, when I turned the scope to the 1.6-arcsecond double Xi Ursa Majoris. Incredible! While a typical eye can resolve Dawes' limit with as little as 12x per inch of aperture, most observers are more comfortable with 20x to 30x and some even prefer 50x or more. Using the Tele Vue 85 at 428x called for a remarkable 125x per inch of aperture! But that's not the end of the story. After the double stars, my next target was the Moon, since I wanted to test the scope for signs of color aberration. If any was present, the Moon's bright limb projected against a dark sky would be where I'd find it. The evening was very steady with the nearly first-quarter Moon high in the western sky. I began with the 20-mm Plössl. The 30x view was incredible with the brilliantly lit Moon standing out in sharp contrast against a jet-black sky. There were no signs of internal reflections to degrade the image. Upping the power to 40x with the 15-mm Panoptic gave an even better view. Numerous craters along the terminator were razor sharp and the ghostly bluish glow of earthshine was clearly visibleóa breathtaking sight. Next I added the Powermate for a 200x tour of the lunar surface. Mountain ranges, rays, rilles, and microscopic craters stood out in sharp, bold relief. For nearly an hour I watched mesmerized as the shadow cast by the rim of Theophilus moved across the crater's floor." -- Sky & Telescope Magazine, September 1998
