Product Details

  • Explore Scientific Waterproof Eyepieces - Comfort, Quality, Value. The Explore Scientific 52° Series™ eyepieces are excellent flat-field multi-element oculars that can transform your visual astronomy experience. With an apparent field of view of 52 degrees, these eyepieces offer incredible value in a very nice eyepiece. Expect exceptional quality and value versus a comparably priced Plossl.

    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.

    Explore Scientific 20mms 1.25" 5 2 degree eyepiece

    Wonderful pinpoint views of stars, and contrast and color is fantastic! Replace an older 2" eyepiece and am I glad. Able to view without glasses for first time, and does that also make a difference. That averted vision really does work. So pleased, I immediately bought a 20 mm version.
