The TeleVue TV85A sharp scope for people on the go
The Tele Vue 85 is ideally suited for day and night use and delivers crisp, colour free views "Redefining the standard of excellence for small-aperture refractors" and "..truly an incredible instrument with superb, well-corrected optics." are just two of the comments made by the reviewer in Sky and Telescope magazine. Made from "special dispersion glasses" the objective is an air-spaced doublet of 600mm focal length. TeleVue maintain that the design has less colour aberration than an f/8 doublet or triplet fluorite objective of comparable aperture. Multilayer anti reflective coatings on the objective's four air to glass surfaces result in excess of 94% light transmission in the visible spectrum, giving the scope 140 times the light gathering capacity of the naked eye. The inside surface of the tube is covered with flat-black textured material to prevent internal reflections. The 2 inch rack-and-pinion focuser is as smooth as silk, and the scope comes with TeleVue's fantastic 2" Everbrite Diagonal. Weighing in at a mere 8 lbs, the TeleVue 85 is well suited to the TelePod and Panoramic mounts. The TV-85 is usually in stock as the Ivory Tube with 2¼ focusser and 2¼ Everbrite star diagonal, 2" to 1¼" adaptor, ring mount and a 20mm Plossl. It is available in brass and Evergreen or as an Evergreen or ivory OTA only by special order with Venturescope. It comes in a fitted bag, and as an optional extra, there is a 45° erecting prism (for terrestrial use) and a Field Flattener (for the more serious astronomical photographers) to eliminate the effects of curvature of field.
