Product Description

  • 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.

ES 62" 40mm is a fantastic value for budget astronomers. I purchased mine for star-hopping and targeting larger deep-sky objects with an 200mm f/5 reflector. In this setup the eyepiece yields a whopping 2.5 degree actual field of view at 25x magnification. I do notice a small bit of coma toward the edge of the field, so I'm purchasing a coma corrector to compliment this eyepiece. Other thing to note: this eyepiece is a beast, requiring a robust focus setup and scope balancing. Overall, I love it. (Posted on 1/7/2019)

Wow! I popped this eyepiece into my Dobsonian and the view was spectacular! Amazing depth of field and eye relief make it easy to focus and a pleasure to view through. Highly recommended. (Posted on 11/19/2018)
