Description
Housed in a lightweight magnesium-alloy body, the PF80-ED assures maximum viewing comfort for the viewer even during many hours of observation in the field. It also features the time-proven porro-prism optics and a large 80mm objective lens incorporating ED (Extra-low Dispersion) glass elements to produce a sharp, clear image with minimal chromatic aberration.
The PF-80ED offers a host of other outstanding features, including: a built-in lens hood to cut excessive light and keep the objective lens free of dust and rain, effortless focusing via an accessible focusing knob, a built-in tripod socket, a long 20mm eye relief for easy viewing, and a rubber housing to protect the internal components and mechanisms from shock and damage.
PENTAX XL Zoom Eyepiece:
This is an ultra-premium six-element zoom eyepiece. It has a long eye relief that's particularly well-suited to those who must wear eyeglasses while observing (such as those with severe astigmatism). It is designed for use with Pentax 80mm and 100mm spotting scopes, but can also be used for astronomical observing in any telescope accepting 1.25" accessories.
ED (extra low dispersion) glass lens elements are used to minimize chromatic aberrations and astigmatism. The result is very good contrast and center resolution, with very little ghosting. A rubber eyecup twists in and out of eyepiece body to optimize your eye position and shield your eye from ambient light. When the eyecup is fully retracted for eyeglass use, the eye relief ranges from 12mm to 18mm, depending on the focal length (magnification) selected. This allows observers with eyeglasses to see the entire field of view at low powers, where the eye relief is 18mm - some vignetting of the field occurs at higher powers for eyeglass wearers.
The flexibility of a zoom to instantly match the magnification to changing lighting or seeing conditions is one of the zoom eyepieces chief advantages. Match that flexibility to Pentax-grade optics and you have an exceptional tool for any observer terrestrial or astronomical.
All of the lenses in the zoom are fully multicoated with proprietary Pentax SMC (Super MultiCoated) antireflection coatings for high light transmission. They are the same coatings as those used on the most costly Pentax camera lenses. For better contrast, in addition to the inside of the barrel being blackened, the edges of all lenses have also been blackened to eliminate any internal reflections within the lenses themselves.
