The Baader Ortho 6mm 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.
