It has a long eye relief that's particularly well-suited to those who must wear eyeglasses while observing (such as those with severe astigmatism). It is designed for use with Pentax 80mm and 100mm spotting scopes, but can also be used for astronomical observing in any telescope accepting 1.25\" accessories. One of four grooves at the tip of its 1.25\" chrome barrel engages a steel pin in the eyepiece port of the Pentax spotting scopes. This keeps the eyepiece from rotating when the knurled rubber power change collar on the eyepiece is turned to change magnifications. Be sure that the pin in the scope body is engaged properly with the eyepiece before tightening the locking collar on a Pentax spotting scope.\u003c\/p\u003e\n\u003cp\u003eAll of the lenses in the zoom are fully multicoated with proprietary Pentax SMC (Super MultiCoated) antireflection coatings for high light transmission. They are the same coatings as those used on the most costly Pentax camera lenses. For better contrast, in addition to the inside of the barrel being blackened, the edges of all lenses have also been blackened to eliminate any internal reflections within the lenses themselves. ED (extra low dispersion) glass lens elements are used to minimize chromatic aberrations and astigmatism. The result is very good contrast and center resolution, with very little ghosting. A rubber eyecup twists in and out of eyepiece body to optimize your eye position and shield your eye from ambient light. When the eyecup is fully retracted for eyeglass use, the eye relief ranges from 12mm to 18mm, depending on the focal length selected. This allows observers with eyeglasses to see the entire field of view at low powers, where the eye relief is 18mm, although some vignetting of the field occurs at higher powers. As you generally are looking only at smaller objects that do not fill the field at higher powers, the loss of some of the field edge due to vignetting is not usually a concern. The barrel of the eyepiece in marked in both magnifications with an 80mm Pentax spotting scope and in focal lengths for astronomical observing. An index mark shows the power in use.\u003c\/p\u003e\n\u003cp\u003eAs with any zoom eyepiece, the precise focal length or magnification of the Pentax zoom at any given point in time is not all that important. The experienced observer invariably adjusts the zoom magnification to match the seeing conditions and object size as he looks through the eyepiece, rather than first setting the zoom to an arbitrary focal length value according to the scale on the side of the eyepiece and using it at that power no matter what the seeing conditions. The flexibility of a zoom to instantly match the magnification to changing lighting or seeing conditions is one of the zoom eyepiece's chief advantages. Match that flexibility to Pentax-grade optics and you have an exceptional tool for any observer - terrestrial or astronomical.\u003c\/p\u003e\n\u003cp\u003eFor astronomical use, the zoom is usable for medium to high power observing with telescopes of all optical designs - from long focal ratio refractors down to fast f\/4.5 Dobsonian reflectors. The eyepiece is relatively heavy and physically large, so some care is needed in balancing free-moving astronomical telescopes (such as Dobsonians) when this eyepiece is in use. The eyepiece container listed below is recommended purely as a replacement should the standard plastic container supplied with the eyepiece be lost or damaged.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFor terrestrial use with 80mm aperture, 520mm focal length Pentax spotting scopes . . . \u003c\/strong\u003e\u003cbr\u003eThe zoom at a barrel marking of 20x is actually 21x with a 93' field at 1000 yards and 18mm of usable eye relief. \u003cbr\u003eAt a barrel marking of 40x it is actually 43x with a 60' field and 12mm of usable eye relief. \u003cbr\u003eAt a barrel marking of 60x it is actually 63x with a 49' field and 15mm of usable eye relief.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFor terrestrial use with 100mm aperture, 630mm focal length Pentax spotting scopes . . . \u003c\/strong\u003e\u003cbr\u003eThe zoom at a barrel marking of 20x actually provides 26x, with a 78' field at 1000 yards and 18mm of usable eye relief. \u003cbr\u003eAt a barrel marking of 40x it actually provides 53x, with a 48' field and 12mm of usable eye relief. \u003cbr\u003eAt a barrel marking of 60x it actually provides 78x, with a 39.5' field and 15mm of usable eye relief.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFor astronomical telescope use in a 1.25\" focuser or star diagonal . . . \u003c\/strong\u003e\u003cbr\u003eThe zoom at a marking of 24mm has a 38 degree apparent field and 18mm of usable eye relief. \u003cbr\u003eAt 16mm (not marked on the barrel, but easily interpolated), it has a 44 degree apparent field and 15mm of usable eye relief. \u003cbr\u003eAt 12mm it has a 49 degree apparent field and 12mm of usable eye relief. \u003cbr\u003eAt 8mm it has a 60 degree apparent field and 15mm of usable eye relief.\u003c\/p\u003e\n\u003ch2\u003eTech Details: \u003c\/h2\u003e\n\u003ctable id=\"product-attribute-specs-table\" class=\"table\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth\u003eWeight\u003c\/th\u003e\n\u003ctd class=\"data\"\u003e19.2 oz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eWarranty\u003c\/th\u003e\n\u003ctd class=\"data\"\u003eLimited Lifetime\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e","brand":"Pentax","offers":[{"title":"Default Title","offer_id":40221634822217,"sku":"PXLZ","price":359.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0573\/7974\/9961\/products\/3772_1.jpg?v=1662966728"},{"product_id":"8mm-brandon","title":"Vernonscope 8mm Brandon Eyepiece","description":"\u003cp\u003eThe 8mm Vernonscope Brandon eyepiece is designed for high power use with any telescope type, at focal ratios f\/7 and above.

Several different extra low dispersion glass types and specialized coatings are employed for improved contrast and longer eye relief than previous Nagler designs, even those acclaimed as being among the finest wide field eyepieces available. At a usable eye relief of 12mm, the 3.5mm Nagler would normally vignette the field of view for eyeglass wearers.

For example, using it with a 2000mm 8\" f\/10 Schmidt-Cassegrain will result in 571x (71x per inch of aperture) and a 0.35mm exit pupil (about 1\/90th of an inch across).

The loss is minimal though, on a par with the contrast loss in an eyepiece\/Barlow combination with the same effective focal length.

At a usable eye relief of 12mm, the 7mm Nagler would normally vignette the field of view for eyeglass wearers.

This medium focal length\/long eye relief Celestron X-Cel LX eyepiece is usable with any scope type, under virtually any seeing conditions - from fair to superb. (Rain, snow, or fog might limit its usefulness, however.)\u003c\/p\u003e\n\u003cp\u003eWith short focal length refractors it is a low power eyepiece. With the 430mm focal length Astro-Tech AT72EDII, for example, it gives you 37x and a 1.62° field more than three times as wide as the full Moon. This is well suited for observing open clusters such as the Pleiades and large nebulas such as the Lagoon. Both will fit nicely into its field when used with the Astro-Tech AT72EDII, with a framework of black sky around the objects to set them off.\u003c\/p\u003e\n\u003cp\u003eThis Celestron is also quite good for medium high magnification observing with long focal length refractors, reflectors, or catadioptric scopes. On a 7\" Maksutov, for example, it yields 222x. This is an excellent magnification for planetary and close-up lunar observing, particularly when the high contrast of the eyepiece is combined with the high contrast of the Maksutov.\u003c\/p\u003e\n\u003cp\u003eIt's a good choice for medium to medium high magnification observing with long focal length refractors, reflectors, or catadioptric scopes - even under average seeing conditions. Its 12mm focal length is nearly ideal for an f\/10 Schmidt-Cassegrain, providing a 0.12mm exit pupil that very closely matches the resolution of the scope to that of your eye. Its performance makes it a much better choice as a second eyepiece than merely doubling the power of most scopes' standard 25-26mm eyepiece with a Barlow.\u003c\/p\u003e\n\u003cp\u003eIts full multicoatings provide high contrast that makes it a good choice for resolving detail in planets and planetary nebulas, while its edge-to-edge sharpness makes it well-suited for lunar, planetary, and globular cluster observing with an SCT. (Some of the larger globulars, such as M13, will fill its 0.35 degree field with such a scope.) Smaller globular clusters appear vivid and nearly three-dimensional. It is also very good for medium power viewing with short focal length refractors and fast focal ratio Dobsonian reflectors.\u003c\/p\u003e\n\u003cp\u003eIt has a twist-up rubber eyecup and a usable eye relief of 16mm, for virtually unvignetted use with eyeglasses.
