From the dainty Tele Vue-60 to the flagship Tele Vue-NP127, Tele Vue employs a companywide philosophy consistent with their entire line of great telescopes & accessories. They produce brilliant optics in several sizes, none too big to use "on location", so you can have the best views capable of whatever aperture you can tolerate in price and weight.
The apochromatic refractor is the telescope design which produces the most breathtaking contrast and resolution, and Tele Vue offers these in six apertures. You won't get the light gathering capacity per dollar of Newtonian reflectors nor the portability for aperture of Schmidt-Cassegrain. But what you will get are views to be envied by both, with the darkest of background sky and the sharpest, widest fields imaginable. Combined with Tele Vue eyepieces or especially the remarkable Bino Vue viewer, the experience cannot be bested by anything one would consider portable.
The Tele Vue-85 combines a 85mm aperture with a longer focal length of 600mm to achieve higher powers with more contrast & resolution. Enjoy the quality of Tele Vue in a size still palatable for being on the move.
