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.

Solidly in the mid-magnification range for most amateur telescopes, the 15mm is a true workhorse for visual observers. If you love deep sky observing, eyepieces in this focal length range not only give healthy increases in magnification, but the contrast enhancement of giving a darker background sky can make all the difference of how galaxies and nebulae appear under suburban skies.

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.
