TeleVue TV-85 85/600 f/7.1 Apochromatic Refractor Telescope OTA
The TeleVue-85 was designed to answer one question: how much optical performance can you fit into a carry-on bag? An 85mm aperture, a dual-element apochromatic objective lens, and a tube length of just 483mm combine to create an instrument that travels without fuss and delivers without compromise. Astronomers, birdwatchers, and optics reviewers all agree - the image is sharp, high in contrast, and free of colour fringing.
What observers and reviewers say
Sky & Telescope magazine reviewed the TV-85 on double stars, lunar detail, deep-sky objects, and astrophotography. Their verdict: "Truly amazing!... Incredible!... the view almost knocked me off my chair!" They concluded: "...a very powerful compact instrument capable of delivering stunning views of the universe." The website Better View Desired added the birdwatcher's perspective - the TeleVue TV-85 apochromatic refractor renders colours with vivid accuracy and resolves detail at a level that makes other instruments feel like a compromise.
Design and key features
Smooth, precise focusing
The focuser uses a rack-and-pinion mechanism with a 1:10 reduction ratio. It allows fine, backlash-free focusing with no sticking or play.
2-inch eyepiece port
The 2″ focuser output accepts a wide range of standard eyepieces and accessories, giving you full flexibility when upgrading your kit.
Ready to use straight away
The TeleVue TV-85 comes complete with a dew shield and a carry case, so it is ready to use as soon as you unpack it. The tube is a single-piece construction with multi-coated lens surfaces throughout.
Built for travel, built for performance
The TV-85 appeals to anyone who refuses to choose between image quality and portability. A weight of 2.7kg and a length of 483mm are not marketing figures - they are the dimensions you will feel in your hand and on your shoulder during a night-sky session or a birdwatching trip.
