Sale
Original price $263.99
Current price $197.99

The Explore Scientific 4.7mm 82° Series Argon-Purged Waterproof Eyepiece is used when very high magnifications are desired. Watch the video on this page below starting at 5:28 where we describe the benefits and conditions that are required to use your telescope at high magnifying power for planetary and double star observations, and for examining the details of many deep sky objects. 

The 4.7mm will not be used every night, but when those times occur when conditions in the sky are near-perfect, you can get views of planetary detail that you will remember for a lifetime with this eyepiece. 

Explore Scientific 82° Series Waterproof Eyepieces - Comfort, Quality, Value.

Explore Scientific 82° Series eyepieces, with their 82 degree 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.

Waterproof Eyepieces Are Easy to Clean and Protect the Internal Lens Elements

All Explore Scientific Waterproof Eyepieces are gas-purged and O-ring sealed which makes them very easy to clean. You can even place them under running water and use generous amounts of lens cleaning solutions to remove stubborn layers (and sometimes sticky) of materials that nature and humans often subject eyepieces to. You can also leave the eyepieces out overnight without fear of them fogging up between the lens elements.
