Fainter deep sky objects that do not have the inherent brightness to be observed at higher powers are often perfect for a 10mm. Explore Scientific Waterproof Eyepieces - Comfort, Quality, Value. The Explore Scientific 52° Series eyepieces are excellent flat-field multi-element oculars that can transform your visual astronomy experience. With an apparent field of view of 52 degrees, these eyepieces offer incredible value in a very nice eyepiece. Expect exceptional quality and value versus a comparably priced Plossl.\u003c\/p\u003e\n\u003cp\u003eAnother great benefit of these eyepieces is the excellent contrast and 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.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cdiv class=\"spanrow\"\u003e\n\u003cspan class=\"speccell speccell-left\"\u003eItem Number\u003c\/span\u003e\u003cspan\u003e \u003c\/span\u003e\u003cspan class=\"speccell\"\u003eEPWP5210–01\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"spanrow\"\u003e\n\u003cspan class=\"speccell speccell-left\"\u003eFocal Length\u003c\/span\u003e\u003cspan\u003e \u003c\/span\u003e\u003cspan class=\"speccell\"\u003e10mm\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"spanrow\"\u003e\n\u003cspan class=\"speccell speccell-left\"\u003eLength\u003c\/span\u003e\u003cspan\u003e \u003c\/span\u003e\u003cspan class=\"speccell\"\u003e83mm\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"spanrow\"\u003e\n\u003cspan class=\"speccell speccell-left\"\u003eWidth\u003c\/span\u003e\u003cspan\u003e \u003c\/span\u003e\u003cspan class=\"speccell\"\u003e43mm\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"spanrow\"\u003e\n\u003cspan class=\"speccell speccell-left\"\u003eWeight\u003c\/span\u003e\u003cspan\u003e \u003c\/span\u003e\u003cspan class=\"speccell\"\u003e181.4 grams; 6.4 oz.\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"spanrow\"\u003e\n\u003cspan class=\"speccell speccell-left\"\u003eBarrel Size\/Type\u003c\/span\u003e\u003cspan\u003e \u003c\/span\u003e\u003cspan class=\"speccell\"\u003e1.25\" O.D. \/ Double Taper\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"spanrow\"\u003e\n\u003cspan class=\"speccell speccell-left\"\u003eEye Relief\u003c\/span\u003e\u003cspan\u003e \u003c\/span\u003e\u003cspan class=\"speccell\"\u003e16.6mm\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"spanrow\"\u003e\n\u003cspan class=\"speccell speccell-left\"\u003eField Stop Diameter\u003c\/span\u003e\u003cspan\u003e \u003c\/span\u003e\u003cspan class=\"speccell\"\u003e9.1mm\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"spanrow\"\u003e\n\u003cspan class=\"speccell speccell-left\"\u003eCoatings\u003c\/span\u003e\u003cspan\u003e \u003c\/span\u003e\u003cspan class=\"speccell\"\u003eEMD (Enhanced Multi-Layer Deposition) on all lens-to-air surfaces\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"spanrow\"\u003e\n\u003cspan class=\"speccell speccell-left\"\u003eLens Elements\/ Groups\u003c\/span\u003e\u003cspan\u003e \u003c\/span\u003e\u003cspan class=\"speccell\"\u003e6 Elements in 3 Groups; Edge Blackened\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"spanrow\"\u003e\n\u003cspan class=\"speccell speccell-left\"\u003eFilter Thread\u003c\/span\u003e\u003cspan\u003e \u003c\/span\u003e\u003cspan class=\"speccell\"\u003eFits Standard 1.25-inch Dia.
