Explore Scientific 62° 40 mm - 2" Eyepiece
This Explore Scientific Waterproof 62° 40 mm focal length eyepiece is the perfect choice for those times you need very low magnification for a wide field of view from your telescope, and you also want the sharpest, wide field, with a relatively light-weight eyepiece. Better yet, this eyepiece is fully waterproof and argon gas purged to prevent fogging.
The 40 mm 62° Waterproof 2" barrel eyepiece from Explore Scientific is a good low power choice for many larger deep sky objects and for sweeping across the Milky Way, or searching for special objects, star hopping, etc.
Explore Scientific Waterproof Eyepieces - Comfort, Quality, Value. The Explore Scientific 62° Series™ 2" barrel 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 nearly parfocal 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.
Explore Scientific Limited Warranty is one year, which converts to the Explore STAR Transferrable Extended Life of the Product Warranty when product is registered within 60 days of purchase.
