The Tele
Vue-NP127is 5/127mm Refractor Telescope from Tele Vue is a stellar
leader in the field of high end imaging telescopes. Tele Vue's
craftsmanship and optical excellence is legendary and this APO pushes
the envelope of excellence. The Tele Vue-NP127is refractor offers a
660mm focal length with an f/5.2 in a precision crafted instrument
designed for CCD astro-photography. The Nagler-Petzval design uses
widely spaced doublets to produce a flat focal plane over a relatively
narrow field of view. The is designation denotes an instrument capable
of accepting Imaging Systems by offering a specific mechanical
architecture for photography. The Tele Vue-NP127is is as optically
mechanically and functionally near perfection as possible for imaging up
to 50mm diagonal chips without detracting from the excellence of its
visual capabilities. The rack and pinion focuser holds up to 12 lbs of
weight while providing the extremely fine focusing control of a 10:1
dual speed pinion assembly. The draw tube allows quick transition from
imaging to viewing. It has an imaging insert ring with four lock screws
which is threaded to accept optical items cameras and CCD attachments.
The focuser itself is a planetary ball type reduction focuser with
extremely sensitive focus adjustment better than 1/10 000. A sliding
metal dew shield screw-on metal lens cover and a hard-shell carrying
case are part of the package. Dark sky watching and imaging doesn't get
any more satisfying than this. The apochromatic refractor is the
telescope design which produces the greatest breathtaking contrast and
resolution and Tele Vue doesn't skimp on the engineering. It won't
deliver the light gathering capacity per dollar of Newtonian reflectors
nor the portability of aperture of a Schmidt-Cassegrain. What it does
deliver are views to be envied by both with the darkest of background
sky and the sharpest widest fields imaginable. Combined with Tele Vue
eyepieces the experience cannot be bested by anything one would consider
portable.
