TeleVue TV-102 4" (102mm) f/8.6 ivory tube/black trim apo
Televue telescopes are of a very high quality albeit at a premium price. 'The TeleVue TV-102 is a 102mm (4-inch) f/8.6 refractor that coaxes apochromatic performance out of an ED glass doublet objective lens. The scope body is ivory, with black trim, and is very solidly built. It has a retractable self-storing dewshield and a 2” rack-and-pinion focuser with helical-cut gears. The focuser has a silky-smooth motion and oversize knobs that make it easy to achieve sharp focus, even at very high powers. The TV-102 comes with a 2” Everbrite dielectric coated star diagonal with 99% reflectivity and a 1.25” accessory adapter. Focuser, diagonal, and 1.25” adapter are all equipped with non-marring brass clamp ring accessory holders. The supplied hardshell carrying case has cutouts to cradle the scope, diagonal, and a number of eyepieces.'
