Explore Scientific 20 mm 62-deg Argon-Purged Waterproof 1.25" Eyepiece
Explore Scientific 20 mm 62º Waterproof Eyepiece - 1.25"
With a 62º apparent field of view and an almost parfocal design, this Explore Scientific 20 mm Argon-Purged Waterproof Eyepieces provides exceptional flat-field multi-element viewing to completely revolutionize your visual astronomy experience. This quality eyepiece offers tremendous value.
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.
