Loved by deep sky observers, a 30mm focal length eyepiece produces a large exit pupil which floods your dilated eye with light, which is needed to see faint galaxies and nebulae. Low power eyepieces are very important to observers for a variety of reasons: Their wide true field of view make object location and pointing far easier.; Many deep sky objects are large and are best viewed at the lowest magnifications your telescope/eyepiece combination can achieve. When seeing conditions are poor, objects will often still look sharp at low powers.
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.
