Product Description

Looking for something out of the ordinary for your next eyepiece?  The Explore Scientific 52° series is a strong contender for necessary addition to your eyepiece collection.  It's long 15mm of  eye relief makes it a joy to put in your scope night after night.

Eyepieces at or near the 10mm range are often considered a mandatory focal length in your collection, as this focal length range is departure point from medium power eyepieces for most telescopes for amateur astronomers. Fainter deep sky objects that do not have the inherent brightness to be observed at higher powers are often perfect for a 10mm. Explore Scientific Waterproof Eyepieces - Comfort, Quality, Value. The Explore Scientific 52° Series eyepieces are excellent flat-field multi-element oculars that can transform your visual astronomy experience. With an apparent field of view of 52 degrees, these eyepieces offer incredible value in a very nice eyepiece. Expect exceptional quality and value versus a comparably priced Plossl.

While some might question the need for Argon-Purged waterproof eyepieces, it is a nice concept knowing the inside of your eyepiece will be just as perfect as the day it left the assembly line.  No need to worry about dust, or cleaning solution, finding its way inside the elements.  These eyepieces are designed to be used night after night giving you complete peace of mind about their performance.
