A logical companion for the “grab-and-go” ED80mm f\/6 Air-Spaced Triplet, this eyepiece produces 160X which will perform very well with good seeing conditions. On the ED152 at f\/8, 405X is achieved without the use of a Focal Extender or Barlow for those nights of near perfect seeing, with a very comfortable 15mm of eye relief.\u003c\/span\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eDesigned for high-power on-axis observations, the Explore Scientific 3mm 52° Series Waterproof Eyepiece is fully EMD (Enhanced Multi-Layer Deposition) Coated with edge blackened lenses providing the contrast required for serious high-power observing of planets, close-paired double stars, and bright compact deep sky objects. With an apparent field of view of 52 degrees, these eyepieces offer incredible value.\u003c\/span\u003e\u003c\/p\u003e\n\u003ch2 style=\"text-align: center;\"\u003e\u003cstrong\u003eSpecifications\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eFocal Length:  3mm\u003c\/li\u003e\n\u003cli\u003eLength:  90.9mm\u003c\/li\u003e\n\u003cli\u003eWidth:  43mm\u003c\/li\u003e\n\u003cli\u003eWeight:  7.2 ounces\u003c\/li\u003e\n\u003cli\u003eBarrel Size:  1.25\", double taper\u003c\/li\u003e\n\u003cli\u003eEye Relief:  15mm\u003c\/li\u003e\n\u003cli\u003eField Stop Diameter:  2.7mm\u003c\/li\u003e\n\u003cli\u003eCoatings:  Enhanced Multi-Layer (EDM) coatings on all lens-to-air surfaces\u003c\/li\u003e\n\u003cli\u003eLens Elements\/Groups:  6 Edge-Blackened Elements in 3 Groups\u003c\/li\u003e\n\u003cli\u003eFilter Thread:  Fits Standard 1.25\" thread (1.125\" x 42 tpi\u003c\/li\u003e\n\u003cli\u003eWaterproof:  O-Ring sealed, gas purged\u003c\/li\u003e\n\u003cli\u003eEyecup:  Removable, Flip-down\u003c\/li\u003e\n\u003cli\u003eLens Caps:  Top \u0026amp; Bottom\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3 style=\"text-align: center;\"\u003e\u003c\/h3\u003e","brand":"Explore Scientific","offers":[{"title":"Default Title","offer_id":17820503408753,"sku":"EXP-EPWP5203-01","price":53.95,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0851\/2766\/products\/EPWP5203-01_3_720x_80179c8d-6cb9-4d31-b1e7-e991f713cd88.jpg?v=1776459029","url":"https:\/\/khanscope.com\/en-fr\/products\/explore-scientific-52-3-mm-waterproof-eyepiece-epwp5203-01","provider":"Khan Scope Centre","version":"1.0","type":"link"}
