The design uses just four glass-air-surfaces, and each is treated with Baader's HT multi-coatings to maximize light transmission and eliminate internal reflections. The result is a bright, distortion-free view with a sharp field stop, presenting celestial objects against a black, scatter-free background.\u003c\/p\u003e\n\u003cp\u003eWhile the apparent field is more constrained than modern wide-field eyepieces, the trade-off is a pristine, high-contrast on-axis view essential for resolving fine planetary detail.

1.25\"\u003c\/h2\u003e\n\u003cp\u003eThe Baader Classic Ortho 10mm Eyepiece delivers a tack-sharp 50° apparent field of view in a true 1.25\" orthoscopic design, purpose-built for high-magnification planetary and solar observing. Its optical path, featuring only four glass-air-surfaces with Baader's HT multi-coatings, maximizes light transmission and contrast to a level where the lenses seem to disappear, revealing the finest details on high-contrast targets.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eThe 50° Orthoscopic View: 4-Element High-Contrast Design\u003c\/h3\u003e\n\u003cp\u003eFollowing the legendary optical design of Zeiss Jena orthoscopics, this eyepiece provides a distortion-free, high-contrast image that excels on planets, the Moon, and double stars. The 4-element design, combined with blackened lens edges and meticulously baffled interiors, virtually eliminates internal reflections and stray light for a dark, clean background field.\u003c\/p\u003e\n\u003cp\u003eThe result is an exceptionally high level of light transmission and on-axis sharpness. The 50° apparent field is framed by a razor-sharp field stop, creating a clean, immersive window that renders planetary details with stunning clarity and color fidelity.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eSolar Projection Safe: Heat-Resistant Cement Tested for 6+ Hours\u003c\/h3\u003e\n\u003cp\u003eUnlike modern eyepieces that use UV-cured cement which can fail under thermal stress, the Baader Classic Ortho is constructed with heat-resistant cement. This critical feature makes it one of the few eyepieces on the market genuinely safe for solar projection. Baader has tested the design for over six continuous hours on 150mm refractors without any damage to the optics.\u003c\/p\u003e\n\u003cp\u003eThe all-metal housing and dual internal field stops are engineered to manage heat effectively during prolonged solar viewing sessions.

Its slim profile allows two eyepieces to be used side-by-side in any binoviewer without interference, providing comfortable stereo views of the Moon and planets.\u003c\/p\u003e\n\u003cp\u003eThis eyepiece is also a powerful tool for high-magnification imaging. It is perfectly suited for classic eyepiece projection using adapters like the Baader OPFA system, allowing you to achieve the large image scale necessary for capturing fine details on planetary surfaces.

The simple, highly-corrected 4-element design prioritizes on-axis sharpness and light throughput over extreme field width, achieving a level of contrast that more complex designs often sacrifice.\u003c\/p\u003e\n\u003cp\u003eFor the dedicated planetary, lunar, or solar observer, this eyepiece represents exceptional value.

1.25\"\u003c\/h2\u003e\n\u003cp\u003eThe Baader Classic Ortho 18mm Eyepiece resurrects a legendary optical design, delivering exceptional contrast and on-axis sharpness in a modern 1.25\" format. Its 50° apparent field of view is rendered by a 4-element system with only four glass-to-air surfaces, a configuration that maximizes light transmission and makes it a definitive choice for critical planetary and solar observation.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eThe Classic 50° Orthoscopic View: 4 Elements for Maximum Contrast\u003c\/h3\u003e\n\u003cp\u003eBased on the original Zeiss Jena orthoscopic eyepieces, the Baader Classic Ortho uses a simple but powerful 4-element design to achieve a view free of distortion. While the 50° apparent field is narrower than modern wide-field eyepieces, this is a deliberate trade-off to deliver the highest possible contrast and resolution at the center of the field, where planetary detail is most critical.\u003c\/p\u003e\n\u003cp\u003eBaader’s HT multi-coatings are applied to all air-to-glass surfaces, and the lens edges are meticulously blackened to suppress internal reflections. The result is a transparent view with a dark background, allowing you to resolve subtle cloud bands on Jupiter and fine rille detail on the Moon without interference from scattered light.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eEngineered for Solar Projection: A 1.25\" Eyepiece with Heat-Resistant Cement\u003c\/h3\u003e\n\u003cp\u003eUnlike many modern eyepieces that use UV-cured cement, the Baader Classic Ortho is constructed with a heat-resistant cement that will not degrade under the intense heat of solar projection. This eyepiece has been tested for up to six continuous hours on 150mm refractors, making it one of the few currently produced eyepieces genuinely safe for this application.\u003c\/p\u003e\n\u003cp\u003eThe entire body is machined from metal, with dual internal field stops designed to distribute heat effectively. This robust, no-plastic construction ensures that focused sunlight will not cause internal components to outgas or melt, preserving the optical integrity of your telescope and the eyepiece itself.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eBeyond Visual: A Sub-35mm Body for Projection, Digiscoping, and Binoviewers\u003c\/h3\u003e\n\u003cp\u003eWith a lean housing diameter of less than 35mm, the Classic Ortho 18mm is exceptionally adaptable. Its primary advantage is for high-magnification planetary imaging via classical eyepiece projection, where its on-axis sharpness can be leveraged to capture fine detail.\u003c\/p\u003e\n\u003cp\u003eThe slim profile also makes it a perfect match for binoviewers, where wider eyepieces can cause issues with nose clearance.

Most modern eyepieces use UV-cured cement that can melt or separate under the focused heat of the sun, permanently damaging the eyepiece.

Its high on-axis sharpness is critical for capturing fine details like the Great Red Spot or subtle cloud bands on Jupiter. When used with an eyepiece projection adapter (like the Baader OPFA), it allows you to achieve the high magnifications necessary to bring the planet to a useful image scale on your camera's sensor.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion\"\u003e\n\u003ch3 class=\"DAV-accordion-Q\"\u003eCan I use the Baader Classic Ortho 18mm eyepiece in a binoviewer?\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion-A\"\u003e\n\u003cp\u003eYes. The slim housing, with a diameter under 35mm, makes the Baader Classic Ortho 18mm an ideal candidate for binoviewers.

The 18mm focal length provides a useful magnification for framing large sections of the Moon's surface or capturing the full disk.
