VERSATILE MAGNIFICATION POWER: With its 18mm focal length, this waterproof eyepiece produces a versatile mid-range magnification that is an excellent choice for observing a broad range of objects from planets to deep sky favorites like nebulae, galaxies, star clusters and more. Under steady skies with excellent atmospheric conditions, fainter objects that cannot be seen with high magnification powers will be revealed in the eyepiece.
BROAD FIELD OF VIEW: The wide 82-degree apparent field of view of this series of eyepieces makes it easier to locate objects in the night sky as well as explore various regions of large celestial treats like nebulae. The generous apparent field of view also relaxes your eye for a pleasant viewing experience and allows you to use averted vision to see fainter targets.
HIGH RESOLUTION VIEWS WITH SHARP CONTRAST: This eyepiece generates brilliant views with crisp definition and rich contrast by using edge-blackened optical elements made of low-dispersion glass with a high refractive index. In addition, each lens element is fully multi-coated with durable enhanced multi-layer deposition (EMD) coatings that maximize light transmission.
WATERPROOF HOUSING: Each 82-degree Series eyepiece is purged with an inert gas and O-ring sealed to create a waterproof environment that is impervious to internal moisture build-up and prevents contaminants like dust from entering the ocular housing.
USA SUPPORT: Should you ever have an issue or question, you can always be assured of excellent support from our Customer Service team based in Springdale, Arkansas, USA.
Explore Scientific 82° Series eyepieces, with their 82° apparent field of view, immerses you in a very comfortable ultra-wide field that naturally promotes relaxation at the eyepiece. When you relax your eyes and take in the scene presented before you, it is much easier to observe for longer periods of time, and details begin to materialize that may not have become apparent to you at first glance. Another great benefit of ultra-wide eyepieces is the ease with which you can gaze, not directly at an object, but slightly to either side. This skill, called using averted vision, is especially helpful when observing faint objects, because using averted vision puts the image on a part of your eye that is more sensitive to light, allowing you to see fainter images.
