The Powermate consists of a negative doublet plus a positive \"pupil-correcting\" doublet.

There were other aspects of equal importance and only the combination of all would satisfy our ethos in creating a \"planetary\" eyepiece: full field sharpness for any speed \u003ca href=\"http:\/\/khanscope.com\/newEquipCart.cfm?catID=1\u0026amp;subcatID=1\" target=\"blank\"\u003etelescope\u003c\/a\u003e, high contrast and transmission for natural color rendition, low scatter, and comfortable eye-relief. Being a zoom, we also concerned ourselves with making sure it was parfocal through the zoom range as well maintaining a constant apparent field of view. The one aspect we were not too concerned with was giving the \u003ca href=\"http:\/\/khanscope.com\/accessDetails.cfm?productID=5224\" target=\"blank\"\u003eTeleVue Telescope Eyepiece\u003c\/a\u003e a wide AFOV. \u003c\/i\u003e\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003eLimiting the AFOV to 50 degrees and the eye-relief to 10mm, we were able to create a compact physical design employing only five elements to reach the \u003ca href=\"http:\/\/khanscope.com\/accessDetails.cfm?productID=5224\" target=\"blank\"\u003eTeleVue Telescope Eyepiece\u003c\/a\u003e optical goals. Like other \"Naglers,\" it utilized a negative lens group ahead of the focal plane. This permitted relatively long eye-relief for very short focal lengths. By independently moving the upper and lower lens groups, we achieved constant focus (parfocality), constant apparent field of view, and essentially constant eye-relief. Just by rotating the upper barrel, you can zoom through the power range. Click stops offer known power points for reference without needing to look at the barrel and instantaneously choose the optimum magnification for the given observing conditions.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003eI was sufficiently confident in the \u003ca href=\"http:\/\/khanscope.com\/accessDetails.cfm?productID=5224\" target=\"blank\"\u003eTeleVue Telescope Eyepiece\u003c\/a\u003e design and purposely decided to attach my name to the zoom, despite the common association between \"Nagler\" and 82 degree AFOV.

Control of astigmatism, field curvature, lateral color, angular magnification distortion correction, and low pupil sensitivity for daytime use were specified criteria and a hallmark of the \u003cb\u003eTeleVue Ethos Eyepiece\u003c\/b\u003e design.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003eFollowing Tele Vue'''s philosophy of pushing the state of the art, long-time Tele Vue employee and optical design protege Paul Dellechiaie took up the challenge and designed the basic eyepiece form.

We can certainly help narrow the field, so to speak, by asking some targeted questions, but when it comes right down to it, choosing the \"perfect\" eyepiece from that point on is all about personal preference.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003eTo some, the most important feature of an eyepiece (besides a sharp, clear image!) is a wide field of view, while to others, long eye relief is #1 on their \"must have\" list. And to make things even more complicated, prerequisites for an eyepiece used mainly for lunar and planetary viewing are usually different than those required for huge objects like galaxies and nebulae. That is why Explore Scientific offers a wide variety of eyepiece designs, like the \u003cb\u003eExplore Scientific 68 Degree Series Waterproof Telescope Eyepiece\u003c\/b\u003e; so that you can pick the features you require and desire, whether you are investigating the deepest reaches of space, the Great Red Spot on Jupiter, or migrating whales just off the coast of California.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003eThe \u003cb\u003eExplore Scientific 68 Degree Series Waterproof Telescope Eyepieces\u003c\/b\u003e were designed for those who prefer longer eye relief but still want to enjoy a field of view that is wider than a classic Plossl or Orthoscopic style eyepiece. If you wear eyeglasses and either want or need to keep them on while observing, the extra long eye relief built into the 68 degree models will allow you to do that and still observe comfortably. As you can see, the eye relief in this series starts at almost 12mm on the 16mm model and increases quickly until it reaches a maximum of 31mm on the 40mm model. There are four Explore Scientific 68 degree eyepieces - the 24mm, 28mm, 34mm, and 40mm - that sport an eye relief of over 18mm, which is perfect for eyeglass wearers. If you wish to increase the magnification of these eyepieces while still maintaining their superb eye relief, use them with the appropriate Explore Scientific Focal Extender, which comes in both 1.25\" and 2\" barrel sizes.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003eOf course, you do not have to wear eyeglasses to appreciate comfortable eye relief, or the quality that lives in each \u003cb\u003eExplore Scientific 68 Degree Series Waterproof Telescope Eyepiece\u003c\/b\u003e.

This development takes the Herschel Wedge into the 21st Century, by rendering the output energy cool and diffused! In all other herschel designs, the waste energy is simply deflected out of the rear face of the prism by an angled mirror. Though quite safe with careful use, the user still had to be aware not to place any object (or body part..) into this output beam (and to prevent any casual onlooker from carelessly staring up into the beam). Thanks to Baader Planetarium, this concern has now been completely removed. In place of the typical output mirror is a coated multi-layered perforated steel screen. The bright light and heat energy are harmlessly diffused. Even after prolonged observations through large refractors, the light trap remains cool. You can even place a hand below the output and no heat can be felt (also, no tempting or hazardous bright output for careless eyes to see).\u003c\/p\u003e\n\u003cp\u003e* Baader now offers two versions of the Herschel Wedge: The lower priced Version-V (visual, sold separately) comes with the pre-installed ND=3.0\/1:1000 (required for safe viewing), and a 2\" Polarizing Filter. The Version-P (photographic, included in this package) starts with the Version-V and adds 3 additional Baader ND filters (ND1.8\/1:64, ND0.9\/1:8, ND0.6\/1:4 ). The additional ND filters are handy for further dimming the image for white light viewing, or attaching to eyepieces or a T2-15 Reducer, and are particularly useful for imaging.\u003c\/p\u003e\n\u003cp\u003e* All of the fine-optically polished genuine Baader ND filters now incorporate special anti-reflection multi-coatings to further eliminate light scatter and ghosting for maximum image contrast. The result is image quality unachievable with any other ND filter.\u003c\/p\u003e\n\u003cp\u003ePlease Note: The Herschel Wedge is only recommended for use with refracting telescopes, \u003cspan style=\"text-decoration: underline;\"\u003eNOT\u003c\/span\u003e Schmidt-Cassegrain, Maksutov, or any other reflecting telescopes. This is a professional-quality white light (not H-Alpha) solar filtration system, whose basic design concept has existed for almost as long as the telescope itself. Like glass or mylar film objective solar filters, it is completely safe if used properly and common sense precautions are always observed.\u003c\/p\u003e\n\u003cp\u003eSimilar in length to any 2\" diagonal, the Baader Herschel Wedge requires more back-focus than a 1.25\" accessory. The path length of the Herschel is 128mm, as measured from it's front face to the top of the 2\" eyepiece holder. Since most 2\" eyepieces have their field stops well below the main eyepiece body, most telescopes will need less than 128mm of back focus to accommodate the Herschel. Most telescopes with 2\" focusers will have no problem providing this amount of back-focus (in-travel). However, some telescopes, such as many TeleVue refractors, provide limited back-focus that may require a shorter path length for some eyepieces. For these scopes the path length of the Herschel may be reduced to 108mm for 1.25\" eyepieces by the attachment of a T2-27 adapter and T2-08 1.25\" Clicklock eyepiece clamp.\u003c\/p\u003e\n\u003ch4 class=\"heading__cXkStmX9s\" data-selenium=\"includesInTheBoxTitle\"\u003eIn the Box\u003c\/h4\u003e\n\u003cul class=\"list__cXkStmX9s\" data-selenium=\"includesInTheBoxList\"\u003e\n\u003cli class=\"item_u6ujeLWy3W\" data-selenium=\"includesInTheBoxItem\"\u003e\u003cspan\u003eAlpine Astronomical Baader Cool-Ceramic Safety Herschel Solar Photographic Prism Mark II\u003c\/span\u003e\u003c\/li\u003e\n\u003cli class=\"item_u6ujeLWy3W\" data-selenium=\"includesInTheBoxItem\"\u003e\u003cspan\u003eBaader 7.5nm Solar Continuum Filter\u003c\/span\u003e\u003c\/li\u003e\n\u003cli class=\"item_u6ujeLWy3W\" data-selenium=\"includesInTheBoxItem\"\u003e\u003cspan\u003e3.0 Neutral Density Filter\u003c\/span\u003e\u003c\/li\u003e\n\u003cli class=\"item_u6ujeLWy3W\" data-selenium=\"includesInTheBoxItem\"\u003e\u003cspan\u003e1.8 Neutral Density Filter\u003c\/span\u003e\u003c\/li\u003e\n\u003cli class=\"item_u6ujeLWy3W\" data-selenium=\"includesInTheBoxItem\"\u003e\u003cspan\u003e0.9 Neutral Density Filter\u003c\/span\u003e\u003c\/li\u003e\n\u003cli class=\"item_u6ujeLWy3W\" data-selenium=\"includesInTheBoxItem\"\u003e\u003cspan\u003e0.6 Neutral Density Filter\u003c\/span\u003e\u003c\/li\u003e\n\u003cli class=\"item_u6ujeLWy3W\" data-selenium=\"includesInTheBoxItem\"\u003e\u003cspan\u003eIP67-Rated Carry Case\u003c\/span\u003e\u003c\/li\u003e\n\u003cli class=\"item_u6ujeLWy3W\" data-selenium=\"includesInTheBoxItem\"\u003e\u003cspan\u003eLimited 2-Year Manufacturer Warranty\u003c\/span\u003e\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Baader Planetarium","offers":[{"title":"Default","offer_id":10552470081,"sku":"BAA-HERSCH-PII","price":940.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0851\/2766\/products\/HERSCHEL_Side.jpg?v=1776459099"},{"product_id":"100mm-ha-etalon-filter-w-b600-for-1-25-focuser-ls100fha1-b600","title":"100mm Ha Etalon Filter with B600 for 1.25\" Focuser - LS100FHa1\/B600","description":"\u003cp\u003e \u003c\/p\u003e\n\u003ccenter\u003e\n\u003ch2\u003eAbout the Lunt 100mm Ha Etalon Filter w\/B600 for 1.25\" Focuser...\u003c\/h2\u003e\n\u003c\/center\u003e\n\u003cp\u003eThis product number is for the \u003cb\u003eLunt H-alpha Single Pass Front Mount Etalon System\u003c\/b\u003e for telescopes with 1.25\" focuser and up to 540mm focal length.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003eIntroducing the \u003cb\u003eLunt LS100 Hydrogen-alpha System\u003c\/b\u003e... a 100mm aperture integrally tuned etalon for use on any customer supplied refractor.
