Explore Scientific 82 Degrees, 1.25" 6.7mm Eyepiece, Argon Purged, Excellent.

Description

Explore Scientific 82 Degrees, 1.25" 6.7mm Eyepiece, Argon Purged. Excellent condition, excellent views. Used only a few times, but I had an opportunity to get a TeleVue Delos 6mm, and these are too much alike to keep both. Original box, instructions, velvet bag, and caps. Has a few pin prick marks on the barrel where I had a parafocal ring (see photo).

Explore Ultra-Wide Eyepieces - Comfort, Quality, Value. Explore Scientific 82° Series eyepieces, with their 82° apparent field of view, immerses you in a very comfortable ultra-wide field that naturally promotes relaxation at the eyepiece. When you relax your eyes and take in the scene presented before you, it is much easier to observe for longer periods of time, and details begin to materialize that may not have become apparent to you at first glance. Another great benefit of ultra-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.
