The multi-coating eliminates almost all internal reflections. The eyepieces provide 50 Degree apparent field (6/10/18mm Ortho), sharp field stops and excellent ergonomics for comfortable observing.Classic optical design of orthoscopic eyepieceshe lens assembly consists of a triplet-element and one plano-convex eye lens, so there are only four glass-air-surfaces. The interior has been blackened for a very good suppression of stray light. Of course, the hard anodised barrel has got a filter thread.Less ThanBrGreater ThanLooking into the eyepieces, you'll see the effect of the anti-relex-coating and the blackened lens edges. The coating is so good that it seems like there are no lenses at all! On our optical bench, we couldn't find any disadvantages compared to so-called "planetary eyepieces" which cost five times more.Less ThanBrGreater ThanThe eyepieces use the same glasses and the same optical design as the old orthoscopic Zeiss Jena eyepieces.The 32mm-Plossl-eyepiece is the perfect eyepiece for a large field of view at telescopes with 1,25"-focuser; eyepieces with longer focal lengths don't provide a larger field of view (but a smaller apparent field).Baader Classic Ortho/Plossl-eyepieces for projection photographyStandard Barlow elements often can not provide enough magnification for taking images of the planet ## Features - Classic Ortho 10mm HT Multi-Coated Eyepiece - Dustcap - Eyecup - Baader Planetarium 1 Year Limited Warranty - Baader Classic Ortho 10mm 1.25" Eyepiece, apparent field of view 52 Degree , incl. winged rubber eyecup - Parfocal Eyepiece series with very high transmission - This eyepiece delivers a pure-white image with outstanding sharpness and contrast - True High-Transmission- (HT) and Multi-Coating (MC) on all glass-air-surfaces offer a brilliant image while showing almost no internal reflections ## Images ![Baader PlanetariumClassic Ortho 10mm HT Multi-Coated Eyepiece with Winged Eyecup, 1.25" Barrel - Image 1](https://m.media-amazon.com/images/I/51wEYCr9wFL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Five Stars *by G***Y on Reviewed in the United States on February 19, 2015* Love this eyepiece for the clarity, color and sharpness. ### ⭐⭐⭐⭐ A Modified Classic *by P***H on Reviewed in the United States on September 6, 2014* Back in the "good old days," you had this amazing choice of eyepieces: There was the Huygenian, otherwise called the blurry soda straw. Then there was the wider angle Kellner. For true quality, however you got the Orthoscopic. It featured crisp images across the "wide," 42 degree field. If you looked at rooftops, they didn't bend, or change shape. All lines were straight. If you looked through a reflector, there was no spurious color. Orthoscopics were what you aspired to.Baader used to have a fairly high end line, called the Genuine Ortho. These, like earlier Ortho brands all came from small shops in Japan. A combination of retirements and the tsunami wiped out Japan as a source. Now the Chinese are stepping in, like they have in so many other instances.Orthoscopics have also run into competition from other designs. Ploessls boast a wider field, though with less eye relief. Various companies produce eyepieces with fields up to 110 degrees. They work very well, too. So has Baader responded to these challenges? Yes, but in ways that no longer make these a "classic Ortho."Physically, they appear to have enlarged the plano-convex eye lens relative to the triplet field lens. They also gave one side of the triplet (the eye lens side) a stronger curvature than the other.The apparent field of view is now 50 degrees. Baader has introduced a lot of pincushion distortion in an effort to maintain sharpness over the field. In addition to the distortion comes a bit of lateral color (color fringing at the edge of the field). A true Abbe design Ortho would have a narrower field, essentially zero lateral color and, no distortion. Aside from the reasonable price, why would anyone want these?I compared this particular eyepiece with two eyepieces from the Baader Hyperion lineup. I compared this with the Hyperion 10mm, and using a Barlow, I compared it to the Hyperion 5.The Classic Ortho shows less color fringing than the Hyperions. Even when Barlowed, the Ortho showed more than the Hyperion 5. When looking at Saturn there was less light scatter, and I was able to glimpse Enceladus, one of Saturn's moons. It was not visible in the Hyperion.That's why you buy these things. The field of view is nothing special. The eye relief is pretty short. Still, they show more for less money. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hr/products/12614118-baader-planetariumclassic-ortho-10mm-ht-multi-coated-eyepiece-with-winged](https://www.desertcart.hr/products/12614118-baader-planetariumclassic-ortho-10mm-ht-multi-coated-eyepiece-with-winged) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-05-18*
