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.

Long considered the “standard” eyepiece that is often supplied with telescopes that are sold by various suppliers, the 25mm focal length category is perhaps the most used eyepiece in the world. Like the 20mm, these eyepieces are great for binoviewer devices, and the 25mm is probably the longest focal length of the mid-power range eyepieces before you get into longer focal lengths.

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.
