In the same way you feel more a part of the action watching a big-screen TV, with Stratus you will feel like you are really experiencing your celestial targets, rather than just viewing them from afar. Each ocular features a monster 1-1/4"-diameter eye lens to look into. Each also has a generous 20mm of eye relief, so you'll get the big picture even if you wear eyeglasses. The optics are fully multi-coated to maximize light transmission to your eyes, and the lens edges are blackened to ensure excellent contrast. Stratus eyepieces fit in both 1.25" and 2" focusers. Each is threaded for filters and comes with protective lens caps.
(2)Celestron Ultima LX Series Telescope Eyepiece - 2inch 22mm - 93375
This 4mm TMB Planetary eyepiece was designed to provide exceptional high power/comfortable eye relief observing with long focal length refractors, reflectors, or catadioptric scopes under average or better seeing conditions. It is optimized to view bright objects, both on and off axis, while showing maximum contrast, detail, and definition. It has very high light transmission, very high contrast, minimal lateral color, and minimal light scatter.
Combine the high resolution of the 4mm TMB planetary with its high contrast and you have an eyepiece that's unexcelled for lunar and planetary observing and binary star splitting. While the 4mm TMB eyepiece is optimized for observing subtle lunar and planetary detail and contrast, the eyepiece works equally well for splitting close binary stars, resolving compact globular clusters, etc. The 4mm focal length of this TMB provides very probably the maximum power possible with an f/10 Schmidt-Cassegrain, as it gives a very high 62.5x per inch of aperture with such a scope. That's more than the 50x-60x per inch of aperture considered the maximum possible under excellent seeing conditions. It provides the 0.5mm exit pupil recommended as the minimum usable for maximum detail with an f/8 focal ratio refractor or reflector.
Eye relief, at 10mm, is quite good for an eyepiece with such a short focal length. Vignetting will only be moderate for those who must wear eyeglasses while observing. This usually won't be a problem when using the TMB Planetary eyepiece on the kinds of objects for which it was optimized - planets, binary stars, etc. - as these small objects are generally kept in the center of the eyepiece field, where your eyesight is sharpest.
For Dobsonian users and others without tracking drives, the very low lateral color and other aberrations of the 4mm TMB allow a planet to drift across its entire 58 degree field while still being sharp and having high cont
With their 66-deg apparent field of view, our Expanse wide-field eyepieces will definitely turn up the Wow! factor in your deep-sky observing experiences! Imagine taking in objects like the Andromeda Galaxy, the Double Cluster, or the star clouds in Sagittarius in one sweep! With an Expanse in your focuser, you can! Expanse oculars have big eye lenses and great eye relief 18mm. Eyeglass wearers can view the entire field without removing their glasses. All eyepiece elements are fully coated, with the outer lens multi-coated for additional light transmission. Each 1.25" aluminum barrel is threaded for filters and internally blackened to eliminate internal scattering. And their fold-down rubber eyeguards enhance contrast by blocking stray light. With our Expanse eyepieces you get a super wide field of view and superior optical performance. And check out the price. You also get a bargain!
This short focal length 5mm TMB Planetary eyepiece is from TMB Optical, the company founded by noted apochromatic refractor designer Thomas M. Back to produce state-of-the-art premium optics. It is designed to give you exceptional high power views with short to medium focal length refractors and reflectors - even under so-so seeing conditions.
The 5mm TMB Planetary has been optimized to show maximum contrast, detail, and definition when viewing bright objects such as the Moon and planets, both on and off axis. It has very high light transmission and contrast, with minimal lateral color and light scatter, to provide exceptional high power observing with long focal length refractors, reflectors, and catadioptric scopes under average or better seeing conditions. It will work with f/10 catadioptric scopes, but its small half-millimeter exit pupil and dim images with such scopes will put it at the very limits of usability. That it does so at such a reasonable price is little short of amazing.
Combine its high resolution with its high contrast and you have an eyepiece that's unexcelled for lunar and planetary observing and binary star splitting with an SCT. Its 5mm focal length provides 400x (a very high 50x per inch of aperture) with an 8" SCT, about the practical maximum magnification possible under excellent seeing conditions. Eye relief, at 12mm, is surprisingly good for an eyepiece with such a short focal length. Vignetting will only be moderate for those who must wear eyeglasses while observing. This usually won't be a problem when using the TMB Planetary eyepiece on the kinds of objects for which it was optimized - planets, binary stars, etc. - as these small objects are generally kept in the center of the eyepiece field, where your eyesight is sharpest.

Allows the use of 2-Inch slip fit accessories such as the Series 5000 2-Inch Enhanced Diagonal on all LX, LS and LT telescopes.
Edge-On Planetary eyepieces bring flat-field performance to solar system viewing in the form of three high-magnification focal lengths. Each employs a sophisticated 7-element lens design reminiscent of exotic, high-priced oculars to provide a sharp focus all the way to the edge of their wide 55-degree apparent field of view. The barrel distortion and field curvature aberrations common in standard eyepiece designs are virtually gone. Edge-On Planetary eyepieces let you push the power, whether you're canvassing the lunar terminator or studying the Jovian cloud belts. The 7-element optics are fully multi-coated for high light transmission, and each eyepiece has 20mm eye relief for viewing comfort. Other nice touches: blackened lens edges, pop-down rubber eyeguards, and barrels threaded for 1.25" filters. Barrel diameter: 1.25".
Backordered from the manufacturer
The Baader Planetarium Hyperion 68 degree Modular Eyepieces offer world-class performance and unique photo-visual features, at an unheard of price. No longer do amateurs need to spend more on their eyepieces than their primary instrument, in order to get true high-end performance in a wide-field eyepiece. Not just a different branded version of their highly regarded cousins, the Hyperions have been totally redesigned to deliver better transmission, contrast, and useful new features. Baader Planetarium has worked hard to give the Hyperions the world's finest optical coatings, superb mechanics, and their unique multifunctional design.
As a visual eyepiece, we have found the Hyperions deliver superb sharpness and color fidelity across their 68 degree wide, flat-field, even in fast telescopes. In our own comparisons to our personal favorites, the Pentax XL, the Hyperions matched the Pentax in every regard, and at just over 1/3 the price! From their superb on-axis and off-axis sharpness, to their pitch-black high contrast field, the Hyperions really work. Viewing through a Hyperion is notably comfortable and relaxing, due to their forgiving eye-position, 20mm of eye-relief, extra-large eyelens, and an optical design that is free of annoying 'kidney-beaning' and blackouts.
Some highlights of the Hyperion;
Consisting of 8 elements in 5 groups (3.5mm - 21mm), the Hyperion optical design delivers outstanding sharpness and color correction over a 68 degree wide apparent field (65 degree for the 21mm). The Hyperion optical design has been chosen to deliver a exceptionally comfortable view, thanks to its 20mm of eye-relief, large eyelens, and a pupil free of the kidney-beaning and blackouts common in many wide field eyepieces.
The new 24mm uses a different optical design and delivers the same outstanding performance over it's 68 degree w
This is a brand new 16X wide field microscope eyepiece. It is Achromatic (International DIN/JIS) standard size with outside diameter of approx. 23 mm. It fits most common size microscopes. Give your microscope a boost with greater power & clarity at a fraction of cost.
Baader Planetarium has evolved the wide-field astronomical eyepiece to a new level.
Introducing the world's first production Astronomical Eyepieces to use aspheric surfaces, the 31mm and 36mm Baader Hyperion-Aspheric 72 degree Modular Eyepieces. This new technology has allowed Baader to eliminate eyepiece aberrations without the usual penalty of extra lens elements, excessive size and weight, or high cost.
The Hyperion Aspheric's freedom from blackouts, kidney beaning, and lack of distortion combines with their long eye relief to produce a view that is uncommonly comfortable and natural for all users (including eye-glass wearers and users of popular astigmatism correcting lenses).
The ultra-wide 72 degree field is extremely flat and distortionless (virtually free of angular magnification distortion)
Baader's renowned Phantom Group Multi-Coatings and thorough internal baffling produce an extremely bright and high contrast view that is free of scatter.
Superb for projection imaging. The Hyperion-Aspherics are threaded to accept the full line of Hyperion Digital T-Rings, for a robust direct attachment of almost any camera. The clever use of 2"x24tpi SCT threads for attaching the 2" barrel permits the Hyperion-Aspherics to directly thread onto the rear cell of popular SCTs. This results in the highest rigidity possible for imaging.
Dual Barrel Configuration - two barrel sizes are provided with each Hyperion Aspheric. The standard 2" barrel provides the full 72 degree field size, and a special wide-field 1.25" barrel provides the maximum true field ever in a 1.25" format, with a field stop size of 1.265"(32mm) perfect for extracting every bit of field possible in 1.25" telescopes or binoviewers.

Tele Vue Barlows: "An Optically Perfect Window" Properly designed Barlows do wonderful things. First, they amplify power while retaining the eyepiece's eye-relief. Second, they slow the telescope's f/#, which improves eyepiece sharpness. Third, the designer can introduce compensations for eyepiece aberrations. Tele Vue's 1 1/4" 2x and 3x Barlows were envisioned as magnification windows. Multi-coated high index glasses assure optimum aberration correction, exceptional contrast and virtually no light loss. Tele Vue Barlows achieve their design goals even when tested by the fastest scopes. The Tele Vue design approach includes mechanical conveniences. The Barlows are parfocal with Tele Vue eyepieces. The 3X Barlow is threaded for 1 1/4" filters.
