The Baader Ortho 10mm eyepiece uses the same glasses and optical design as the classic Zeiss Jena orthoscopic eyepieces. They feature a very high transmission, very good contrast and thus a very clear field of view, free of distortions. The HT-MC multi-coating eliminates almost all internal reflections.

Baader Ortho eyepieces provide 50° apparent field (6/10/18mm Ortho), sharp field stops and excellent ergonomics for comfortable observing. They are parfocal so no refocusing between eyepieces is needed.

The 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. The hard anodised barrel has got a filter thread.

Standard Barlow elements often can not provide enough magnification for taking images of the planets. Classical eyepiece projection is the solution if you want to increase the focal length by 4x or more. The Classic Orthos provide the necessary high magnifications in combination with an OPFA (Eyepiece Projection adapter - sold separately). Orthoscopic eyepieces are well-known for high sharpness on the axis and very good transmission – perfect for planetary observations. So, it is possible to get sharp views of the planets even at very high magnifications.

Splendid views

Two were bought for use in the new Baader Maxbright II binoviewer, and prove to be a perfect match in my 60mm f/15 (FOA-60Q), 105mm f/6, and 130mm f/7 refractors. They are now the preferred eyepieces for quick bino use in the 60mm, their small size and excellent clarity being perfect, usually for planetary and lunar viewing. The Baader Morpheus 6.5mm combination is more powerful for the same true field of view, but they are best left to the larger scopes on a motorised tracking mount. Even so, even on them these 10mms are my go to for planetary and lunar viewing because they fit so easily and neatly. They are sitting in the Maxbright now (06 July 2023) in the dehumidified cupboard just waiting for the clouds to go away - I am ever hoping to watch more of Venus' waning into her beautiful crescent.
