Explore Scientific 6.5 mm 82-deg LER Waterproof Eyepiece

Explore Scientific 6.5 mm 82º LER Waterproof Eyepiece

As with all Explore Scientific 82 Degree Argon-Purged Waterproof Eyepieces, this 6.5 mm LER ocular emphasizes comfortable viewing by offering an especially long eye relief, 16.8 mm in this case. Long eye relief is essential for eyeglass wearing observers because without it, they wouldn't be able to enjoy the full field of view.

Despite not being the shortest focal length eyepiece in the 82º series, the 6.5 mm focal length will still generate high magnifications optimal for lunar, planetary, and binary star observing. Under near perfect atmospheric conditions, you'll be able to experience incredible planetary details as well as examine the inner structures of deep sky objects such as nebulae with this eyepiece.

Edge-blackened optics consisting of high refractive index low-dispersion glass allows this multi-element eyepiece to achieve better light transmission. Full multi-coatings of durable enhanced multi-layer deposition (EMD) coatings can be found on each lens. These elements combine to optimize your telescope's potential for capturing the celestial marvels with which you are most fascinated in sharp contrast, resolution, and detail.

Given that this eyepiece presents an ultra-wide 82º apparent field of view, users are treated to an enveloping celestial observing experience while simultaneously permitting your eyes to relax so that more of the scene presented before you can be enjoyed for longer periods. First glimpses of objects rarely uncover more than superficial detail, but with the viewing time allotted by this eyepiece, much more sophisticated detail will begin to materialize. In addition, this eyepiece’s broad field of view facilitates the use of averted vision. This is a technique used to put faint objects in the part of the eye that is more light sensitive by looking slightly askew from your target object instead of directly at it. 

All Explore Scientific waterproof eyepieces are gas-purged and O-ring sealed to create a waterproof environment that is impervious to internal fogging and prevents contaminants like fungus and dust from entering the ocular housing. This design makes cleaning the eyepiece a breeze.
