Explore Scientific 5.5 mm 100º Argon-Purged Waterproof Eyepiece - 2" - EPWP10055-01

Explore Scientific 5.5 mm 100° Waterproof 2" Eyepiece The 5.5mm 100° Series™ eyepiece by Explore Scientific is part of an ultra-wide class of oculars that will revolutionize your astronomy observations. Enjoy the picturesque wide expanse of inky black sky you will see in the 100° Series eyepiece. The Explore 5.5mm 100º Eyepiece has over 10mm of eye relief. This Explore Scientific eyepiece is designed to increase the comfort level for long nights of observing as well as give you an amazingly immersive visual experience.   Another great benefit of hyper-wide eyepieces is the ease with which you can gaze, not directly at an object, but slightly to either side. This skill, called using averted vision, is especially helpful when observing faint objects because using averted vision puts the image on a part of your eye that is more sensitive to light, allowing you to see fainter images.   About the 100° Argon-Purged Waterproof Eyepiece Series from Explore Scientific Optimized Optical Design E
