Explore Scientific 40mm 62° 2" Waterproof Eyepiece

Explore Scientific Waterproof Eyepieces - Comfort, Quality, Value. The Explore Scientific 62° Series™ eyepieces are excellent flat-field multi-element oculars that can transform your visual astronomy experience. With an apparent field of view of 62 degrees and near par focal design, these eyepieces offer incredible value in a very nice eyepiece.  Another great benefit of these eyepieces is the excellent contrast and 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.
