Product Description

SV80ED BLOWOUT SALE - Save $100 and get free shipping ono this special version SV80ED. We have made the 80ED even better than before. The Stellarvue’s 80ED comes with our 2.5” rack and pinion focuser with 2” and 1.25” adapters. Unlike competing 2” focusers, this focuser works with our threaded photographic field flatteners. The SV80ED has a lightweight aluminum tube and dew shield. It weighs only 4.8 pounds without the mounting rings, 6.4 pounds with them. It comes with dual rings, with a 6 mm threaded hole on the bottom, 2.5” Stellarvue rack and pinion, dual speed focuser with 2” and 1.25” compression ring adapters and a C19 heavy duty, airline carry on travel case. 

Additional Info

This telescope uses the same objective lens design as all Stellarvue ED telescopes.  The objective is a hand figured 80 mm clear aperture, 560 mm focal length (f/7)  air-spaced doublet lens. The extra low dispersion (ED) glass to reduce chromatic aberration or color fringing. Color correction and contrast is considerably better than an 80 mm f-7 doublet achromat. While no f-7 doublet can give you the reflector like color correction of one of our apo triplets, this optic comes very close.

Fully multi-coated objective: The hand figured ED lens provides high contrast with several extreme broadband  coatings used on all four lens. This boosts contrast: the stars appear vivid and the background, velvet black. These coatings  transmit light above and below the visual spectrum, which is important to minimize reflections seen on ccd images.

Stardust White aluminum tube and dew shield: The tube, dew shield, and  fittings are precision machined. All aluminum parts are black anodized with a polished, high gloss finish. The dew shield retracts, reducing the length of the telescope to only 17.5" when being stored and extends to minimize dewing of the  objective at night. It can also serve as a glare shade during the day.

Internal tube treatment:  The inside of the tube assembly is painted "ultra flat black" and is fully baffled to eliminate reflection. The focuser is ultra flat black inside to reduce draw tube reflections.

Stellarvue 2.5” dual speed, rack and pinion focuser:  Designed especially for smoother imaging, our new precise, dual speed rack and pinion focusers now come standard on all Stellarvue telescopes. These are fully rotating using an over-sized rotation collar and thumb screw. Tension control thumb screw underneath holds tight and eliminates all side play. For visual users, these focusers are ultra smooth and free of vignetting. For imagers, our dedicated field flatteners thread directly into each focuser, maintaining precise alignment. This is far superior to 2” Crayford focusers that are not threaded for accessories.

Supplied accessories: This telescope comes with dual mounting rings, focuser, 2” and 1.25” adapters, caps and case. To operate the telescope you will need a star diagonal or erecting prism, eyepiece(s) and a mount and tripod. The mount may require a rail or plate.

Light gathering and magnification power: The 80ED gathers 131 times the amount of light the naked eye can, revealing faint objects in space. Magnification power is dependent upon the eyepiece being used. Different eyepieces provide different magnification powers. Since our 80ED uses a highly accurate, hand figured objective lens that has been tested three times in the USA, these telescopes are free of coma and astigmatism seen in many import telescopes. This provides sharper details when viewing at higher powers. Dawes limit states that the maximum power for an 80 mm telescope under good conditions is about 186 power. Check the "Recommended Accessories" section to make the best choice for eyepieces.

Two year warranty and Stellarvue Service:  Stellarvue telescopes and accessories are covered by a two year warranty. But it  does not stop there. Since we are a telescope maker, we can repair your telescope for a nominal fee years after it goes out of warranty, should you accidentally drop it on concrete or otherwise damage it. Buy a Stellarvue  Telescope with confidence. Our customer care is legendary.
