You may be startled at the amazingly wide expanse of inky black sky you behold the first time you bring your eye to a 100° Series eyepiece, and after awhile, you may even forget that you have an eyepiece between you and the universe! With an apparent field of view that is close to the maximum for hyper-wide eyepiece design, objects are not only easier to locate, but for non-driven telescopes the object will stay in the field of view for a very long time before any adjustments need to be made.\u003c\/p\u003e\n\u003cp\u003eAnother great benefit of hyper-wide eyepieces is the 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\u003cspan\u003eExplore Ultra-Wide Eyepieces - Comfort, Quality, Value. Explore Scientific 100° Series eyepieces, with their 100° apparent field of view, immerses you in a very comfortable hyper-wide field that naturally promotes relaxation at the eyepiece.

The 100° Series eyepieces 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.

The 62° Series eyepieces are near par-focal (meaning they focus at nearly 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\u003eExplore Scientific Waterproof Eyepieces - Comfort, Quality, Value. The Explore Scientific 62° Series eyepieces are excellent flat-field multi-element oculars that can transform your visual astronomy experience. With an apparent field of view of 62 degrees and near par focal design, these eyepieces offer incredible value in a very nice eyepiece. \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.

That means that every air-to-glass lens surface is multi-layer coated for the highest possible light transmission and better contrast. You'll see more of those pinpoint star images and more faint detail in deep-sky objects. In addition, the lens edges are blackened for additional contrast enhancement.

The 52° Series eyepieces are par-focal (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\u003cspan\u003e\u003c\/span\u003e\u003cspan\u003e\u003c\/span\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.

In other words, 3 eyepieces offer 6 magnification choices with the addition of a focal extender. \u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eSecondly, w\u003c\/span\u003e\u003cspan\u003ehen using a focal extender to increase your magnification, you get to enjoy the generous eye relief of the lower power eyepiece, and that's quite a bonus, especially for eyeglass wearers or for those with fast telescopes who can really push high magnification eyepieces. \u003c\/span\u003e\u003c\/p\u003e\n\u003ch5\u003e\u003cspan\u003eSpecifications\u003c\/span\u003e\u003c\/h5\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ctable height=\"250\" width=\"100%\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd bgcolor=\"#dad4d4\" width=\"28%\"\u003eDescription\u003c\/td\u003e\n\u003ctd bgcolor=\"#dad4d4\" width=\"70%\"\u003e2x Focal Extender (1.25-inch O.D.)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd bgcolor=\"#eeeeef\"\u003eItem Number\u003c\/td\u003e\n\u003ctd bgcolor=\"#eeeeef\"\u003eFE02-125\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd bgcolor=\"#dad4d4\"\u003eBarrel Size\u003c\/td\u003e\n\u003ctd bgcolor=\"#dad4d4\"\u003e1.25-inch\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd bgcolor=\"#eeeeef\"\u003eLength\u003c\/td\u003e\n\u003ctd bgcolor=\"#eeeeef\"\u003e118mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd bgcolor=\"#dad4d4\"\u003eWidth\u003c\/td\u003e\n\u003ctd bgcolor=\"#dad4d4\"\u003e66mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd bgcolor=\"#eeeeef\"\u003eWeight\u003c\/td\u003e\n\u003ctd bgcolor=\"#eeeeef\"\u003e20 oz;

However, the series can also be thought of as an extension of the long eye relief Nagler Type 4 concept. With the all-new Type 7 design layout, we achieved our goal of Apollo 11-like performance across a series of focal lengths that are eyeglass friendly.\u003c\/p\u003e\n\u003cp\u003e\u003cspan class=\"fs_italic\"\u003e\u003cb\u003eDesign Goals:\u003c\/b\u003e\u003c\/span\u003e The design goal was simple. The performance of each of the Type 7 focal lengths must equal or exceed that of the Apollo 11 eyepiece in the areas of full-field sharpness, contrast, distortion correction, eye relief, and pupil comfort, but across an 82° apparent field of view instead of 85°.\u003c\/p\u003e\n\u003cp\u003e\u003cspan class=\"fs_italic\"\u003e\u003cb\u003eDesign Details:\u003c\/b\u003e\u003c\/span\u003e If you have been waiting for a Nagler series for eyeglass wearers, the Type 7 is it. Combining the expansive 82° apparent field of view with 19 mm of eyeglass friendly eye relief, and large eyelens, the Nagler Type 7s give a new dimension to the \"spacewalk\" viewing effect. An easily adjustable, locking eye-guard is included for those who don't wear eyeglasses. It helps to correctly position your eye to the exit pupil so you don't get too close to the eyelens, as well as blocks contrast-robbing stray light from interfering with the view. Speaking of which, of course we've applied all the optical coating and baffling features Tele Vue eyepieces are known to maximize contrast and complement the fully corrected field; revealing beautifully natural star colors with pinpoint sharpness. The optical layout affords unrivalled parfocality throughout the four focal lengths and even between 1¼\" and 2\" modes when used with the Tele Vue Hi-Hat 1¼\" and 2\" adapter (ASF-8125). The Type 7 series is also parfocal with all other 1¼\" Tele Vue eyepieces (except 40 mm Plössl) when those eyepieces are used in the Tele Vue Hi-Hat 1¼\" and 2\" adapter (ASF-8125). Available in focal lengths of 5.5, 9, 14, and 19-mm, the Type 7s complement the 22-mm Type 4 and 31 mm Type 5 as eyeglass friendly Naglers.\u003c\/p\u003e\n\u003cp\u003eThe Nagler Type 7 models all weigh 19 to 21 oz \/ 540 to 590 gm.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"pageSectionTitle\"\u003e\u003cstrong\u003eWhy Are There 4 Types of Naglers?\u003c\/strong\u003e\u003c\/div\u003e\n\u003cp\u003eTo achieve various features requires different design tradeoffs and thus the different types of Nagler eyepieces.

Threaded barrels accept 1-1\/4 inch Celestron thread-in filters.\u003c\/span\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003ch2\u003e Specifications\u003c\/h2\u003e\n\u003ctable id=\"product-specs-list\" class=\"table-open\"\u003e\n\u003ctbody id=\"spec-block-1\"\u003e\n\u003ctr\u003e\n\u003ctd\u003eFocal Length\u003c\/td\u003e\n\u003ctd\u003e32 mm (1.26 in)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eApparent Field of View\u003c\/td\u003e\n\u003ctd\u003e49°\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eEye Relief (mm)\u003c\/td\u003e\n\u003ctd\u003e22 mm (0.87 in)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNumber of Lens Elements\u003c\/td\u003e\n\u003ctd\u003e4\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBarrel Size (in)\u003c\/td\u003e\n\u003ctd\u003e1.25 in (32 mm)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e","brand":"Celestron","offers":[{"title":"Default Title","offer_id":48027821801731,"sku":"U2604-GM-93323","price":30.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1979\/5379\/files\/506ce76c-1f05-4809-be37-267aef176059.jpg?v=1777409793"},{"product_id":"used-polar-finderscope-cg-5-advanced-vx-cgem","title":"Used Celestron Polar Finderscope CG-5, Advanced VX, CGEM","description":"\u003cp\u003eThis is a Celestron Polar scope for the AVX and CGEM, CGEM II EQ mounts.  It is in perfect condition in its original box.  Save TWENTY BUCKS off of a new one!  \u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003ePolar align your Celestron CGEM, CGEM II, Advanced VX, or CG-5 equatorial mount with this Celestron Polar Finderscope\u003c\/li\u003e\n\u003cli\u003eInserts into the polar finder port at the back of the mount\u003c\/li\u003e\n\u003cli\u003eThe easily identifiable star patterns of the Big Dipper, Cassiopeia and Octans are etched into the reticle, as well as Polaris and the North Celestial Pole, to help with alignment in the Northern or Southern Hemisphere\u003c\/li\u003e\n\u003cli\u003eEyepiece has focus adjustments for reticle clarity\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eGet some help polar aligning your Celestron CGEM II, Advanced VX, or CG-5 mount with the addition of the Polar Finderscope.

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.
