This 30 mm focal length 2" barrel version of the Explore Scientific 52° Series™ eyepieces is best used when you wish to obtain a medium-wide-field magnification from your telescope, whatever type it may be. This 30 mm eyepiece is a convenient focal length for observing many celestial objects including the Moon and planets. It has a standard 2.0" barrel size, and a 19.9 mm eye relief, with a 26.2 mm field stop diameter and it has EMD coated optics for high contrast imagery. This Waterproof eyepiece from Explore Scientific is purged with Argon gas to prevent fogging even under extreme changes in temperature or environmental conditions.
The EMD coated optics used in this Explore Scientific 52° 30 mm Waterproof Eyepiece reduce internal reflections and provide a flat field image with high contrast. Another nice benefit of this eyepiece is the excellent image contrast and ease with which you can observe using averted vision. This skill, not looking directly at an object, but slightly to either side is especially helpful when observing faint objects. Using averted vision puts the image on a part of your eye's retina that is more sensitive to light, allowing you to see fainter images than you would by "looking directly" at the object.
