Pentax

PR-80ED-AThe PENTAX PF-80ED-A features a 45-degree slanted lens barrel for comfortable viewing in almost any situation. 

Housed in an exceptionally lightweight magnesium-alloy body Incorporating Extra-low Dispersion (ED) glass elements for optimum optical resolution Large 80mm objective lenses for bright viewing under all light conditions The body incorporates the American standard 1-1/4" diameter eyepiece receptacle, which accepts not only the optional Pentax XW eyepieces, but also other telescope manufacturers' eyepieces on the market

The receptacle has a special "O" ring assembly, which allows the body of the scope to be filled with nitrogen, making it fog proof and JIS Class 6 waterproof A built-in lens shade cuts excessive light and helps to prevent rain and other weather elements from interfering with viewing An extra wide focusing knob is incorporated for effortless focusing

A tripod socket with a click-stop rotation mechanism is available to allow for different viewing angle options Famous Pentax Super-Multi-Coating maximizes light transmission, clarity and contrastAn extendable eyecup allows variable adjustment for up to a full 20mm of eye relief, allowing those wearing eyeglasses the same view as non-eyeglass wearers Equipped with a durable rubber housing to protect against shock and damage

Accepts PENTAX XW Telescope Eyepieces: XW7(71x), XW10(50x), XW14(36x), XW20(26x), and the 20X-60X Zoom Eyepiece.

The Remote Control F is an infrared remote release that?s compatible with all K-series DSLR cameras. You can trigger the shutter with a press of the button at several feet away from the camera body. It also fits snugly into the BG2 battery grip for the K10D and K20D DSLR cameras!

The Pentax SMC eyepiece is designed for use with our 65mm scopes. The eyepiece has a high-refraction, low-dispersion lanthanum glass elements to provide high-resolution images with minimal aberrations and the Pentax-original smc full-surface multi-layer lens coating to improve light transmission efficiency. Advanced computer simulation design technology was used to drastically reduce internal reflections producing brighter, clearer images. JIS Class 4 weatherproof construction make these eyepieces more durable and water resistant and has the Pentax Worry-Free Warranty.

70° Apparent Angle of View, 20mm Eye Relief, plus Weatherproof Body for Multi-Application Viewing Clear, Comfortable Viewing Assured by 70° Apparent Angle of View and 20mm Eye Relief All smc PENTAX XW-series eyepieces feature an extra-wide 70-degree apparent angle of view and an extra-long 20mm eye relief to deliver an exciting, wide-perspective image. High-Grade Optics for Exceptional Image Quality The high-performance XW-series optics incorporates high-refraction, extra-low-dispersion lanthanum glass elements to produce a well-balanced image with minimal aberrations. It is particularly designed to reduce the disturbing blackout effect by effectively compensating the spherical aberration of the pupil. PENTAX-Original Multi-Layer Coating for Outstanding Light Transmission Efficiency All lens surfaces that come in contact with air are treated with the original multi-layer coating, while all laminated surfaces are treated with the innovative partial coating, to offer the light transmission efficiency of more than 90 percent (an astonishing 96 percent at 550nm) over the visible light spectrum. Advanced Light-Shielding Technology for Improved Image Contrast Thanks to PENTAX’s advanced computer simulation technology, the XW series features a light-shielding diaphragm at the most effective position to drastically reduce internal reflections for a brighter, higher-contrast image. A Choice of Six Magnifications to Meet Specific Applications With six different magnifications (3. 5mm, 5mm, 7mm, 10mm, 14mm and 20mm) to choose from, the XW series accommodates a wide range of both casual and specialized applications. Weatherproof Construction for All-Weather Viewing The XW series features JIS Class 4 weatherproof construction*, making it possible to use it in drizzle or under night dew. * The XW-series eyepieces are not designed for underwater use and should not be submerged under water. Standard Eyepiece Sleeve and Built-In Adapter-Mounting Screw The XW series features the American-standard 1. 25” tube (31. 7mm) for smooth, easy installation on ANY telescope and/or PENTAX spotting scopes. When the rotatable eyecup is removed, it also offers an optional adapter-mounting screw/thread (43mm in diameter with a 0. 75mm pitch).
