Meade Series 4000 8mm-24mm Zoom Eyepiece (1.25") - This is an excellent addition to telescopes of all types, brands, and price levels from entry level to research grade. A terrific value, especially useful for terrestrial observation to zoon in on potentially moving wildlife.
Offers the ability to change magnifications "on the fly" yet demanding no compromise in performance. The eyepiece?s internal optics move on smooth, precisely machined surfaces which maintain optical collimation at all continuously variable zoom settings. The 6-element 4 group design has 15-18mm of eye relief, and provides an apparent field of view of 40° at 24mm, increasing to an apparent field of view of 60° at the highest power 8mm setting. All lenses are multi-coated for maximum light transmission and image contrast, while minimizing internal reflections.
Features a precision made 1.25" barrel, and fold down eyeguard for comfortable viewing and blocking stray light. The Series 4000? 8mm-24mm Zoom Eyepiece (1.25") offers a complete focal length range from 8mm to 24mm (in a single eyepiece) without sacrificing resolution compared to fixed focal length oculars.

The edge-to-edge angular diameter of the image displayed in a binocular as seen by the eyes of the observer. It is an inherent specification for a given binocular design. The "angular diameter" of an object is defined as the angle an object makes (subtends) as seen by an observer.
Binocular lenses and prisms are often coated with anti-reflective material to minimize light loss as light travels through the multiple optical surfaces of a typical binocular. Coatings help maximize the amount of light transmitted through each glass surface of a binocular, so as much light as possible reaches the observer's eyes to provide a bright and sharp image.
Good lenses are at least "fully coated," with a single layer of magnesium fluoride coating applied to each air-to-glass lens surface. Multiple layers of coatings are even more effective; the term "multi-coated" means one or more air-to-glass lens surface has multiple coatings. "Fully multi-coated" optics are even better, meaning all lens surfaces have multiple layers of anti-reflective coatings applied for maximum light transmission and optimal image quality.
