The visual effect of these eyepieces with their long eye-relief and their 68° apparent field is truly a full-immersion experience. The 68° Series eyepieces are parfocal (meaning they focus at near the same point regardless of the focal length you select) and come with a removable and foldable soft silicone rubber eyecup for the comfort of the observer, and as experienced astronomers know, eye comfort is critical when trying to observe at the visual limits of the telescope.\u003c\/p\u003e\n\u003cp\u003eProtection from the Outdoors - By making the eyepiece body Argon-purged, the waterproof eyepiece internal elements will remain as pristine as the day they were assembled.\u003c\/p\u003e\n\u003cp\u003eArgon atoms are larger than that of Nitrogen and therefore they are less likely to leak or diffuse their way through the seals over the life of the eyepiece. The atomic radius of Argon is larger than Nitrogen by 0.13 angstroms and has a larger atomic volume by 11.2 cubic centimeters\/molecule. Argon also has superior inertness vs Nitrogen (i.e. forming few or no chemical compounds with other elements) that prevents adverse reactions with eyepiece components and therefore extends the longevity of the internal components, and also prevents chemical reactions with other elemental contaminants that may be introduced through a weakened seal. And, finally because Argon is less conductive of heat than Nitrogen, Argon cools slower thereby buffering the effects of rapid temperature changes of the optics.\u003c\/p\u003e\n\u003cp\u003eThe sealed, dry environment is impervious to internal fogging and contaminants such as fungus growing in between the lens elements. Our waterproof eyepiece is easier to clean, and there is no risk of cleaning solution migrating from the top of the lens and seeping around edges to be trapped in between elements. To insure a perfect seal we test every eyepiece in one meter of water for 30 minutes.\u003c\/p\u003e\n\u003cp\u003eSpecs:\u003c\/p\u003e\n\u003cp\u003eFocal Length: 24mm\u003c\/p\u003e\n\u003cp\u003eLength: 75.6mm\u003c\/p\u003e\n\u003cp\u003eWidth: \u003cspan\u003e56.2mm\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eWeight: 11.6oz; 329g\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eBarrel Size: 1.25\"\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eEye Relief: 18.4mm\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eField Stop Diameter: 27.2mm\u003c\/span\u003e\u003c\/p\u003e\n\u003c!----\u003e","brand":"Explore Scientific","offers":[{"title":"Default Title","offer_id":51750255100137,"sku":"dkc1787928575437","price":78.09,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0766\/6964\/9129\/files\/explore-scientific-68-series-24mm-waterproof-eyepiece_1.jpg?v=1787928579"},{"product_id":"explore-scientific-45mm-82-series-ler-waterproof-eyepiece","title":"Explore Scientific 4.5mm 82° Series LER Waterproof Eyepiece","description":"\u003cmeta charset=\"UTF-8\"\u003e\n\u003cp data-open-accessibility-text-original=\"16px\" data-mce-fragment=\"1\"\u003eWith its particularly long eye relief of 15.9mm, the 4.5mm LER ocular from Explore Scientific’s 82° Series of Argon-Purged Waterproof Eyepieces puts the focus on a comfortable viewing experience for all observers.

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 were not revealed at first glance. The broad field of view promotes the use of averted vision, which involves looking slightly to the side of a target object rather than directly at it. This 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.\u003c\/p\u003e\n\u003cp data-open-accessibility-text-original=\"16px\" data-mce-fragment=\"1\"\u003e\u003cbr data-mce-fragment=\"1\"\u003eAll 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.
