## Description

PF-100ED 100mm Spotting Scope (Straight Viewing, Eyepiece Required)

## Features

- Eyepiece required for proper use ,The large objective, superior lens glass, and other optical features make this ideal for hunting, birding, nature watching, and for use as a beginner telescope for the moon, sun (with proper solar filter), and planets. Collet-style press-fit eyepiece holder holds the eyepiece firmly in place and optically centered. Extra-large 100mm objective lens configuration produces a bright and clear field of view that is optimized for long-distance spotting, even in challenging light conditions.
- High-resolution extra-low dispersion (ED) rare earth lanthanum crown glass elements deliver sharp, high-resolution images with minimal chromatic aberrations. BAK4 Porro prism light path eliminates the internal interference suffered by roof prism designs, ensuring crisp views with high resolution.Proprietary SMC (Super-Multi-Coating) multi-layer coatings on lenses maximize light transmission to produce accurate color fidelity with improved contrast and clarity.3-element/3-group eyepiece lens configuration improves image quality by reducing lens-edge distortion.
- Eyepiece holder is set in-line with the body, making finding subjects fast and tracking moving targets easier versus angled-viewing models. Low-profile focusing knob reduces snag hazards—especially when removing from and placing body in the included case.Rotating tripod collar allows the user to adjust the orientation of the eyepiece holder to the tripod head to achieve optimum viewing comfort.Standard 1/4"-20 tripod mount makes it compatible with a wide assortment of photo/video/field tripods, heads, and quick release plates and other support systems like window mounts.
- Integrated sight aids in finding elusive targets like small game and birds before looking through a magnified eyepiece.Built-in lens shade cuts excessive light from causing lens flares on the objective and helps to prevent rain and other weather elements from interfering with view.Accepts all standard 1.25" telescope eyepieces, allowing a wide variety of fixed and zoom options.Four optional wide-angle XW-series eyepieces available separately: Three cost-efficient XF-series eyepieces and one versatile zoom eyepiece.
