The Explore Scientific 20 mm Argon-Purged Waterproof Eyepiece features an almost parfocal design and a 62º apparent field of view for a superb multi-element flat-field viewing experience. Packed with quality, this eyepiece will revolutionize your visual astronomy experience at an affordable price.
An additional benefit of this 20 mm 62º Series™ eyepiece is the stellar contrast it provides, allowing the use of averted vision. This skill gives observers the ability to look slightly to either side of an object instead of directly at it. This can be particularly advantageous when viewing faint objects because using averted vision puts the image on an area of your high with higher light sensitivity, letting fainter images reveal themselves to you.
