The classic orthoscopic eyepiece has some advantages over popular Ploessl eyepieces of the same focal length, but especially compared to modern 'super-wide angle eyepieces':
- the low number of lens elements used results in very high light transmission with very high contrast and therefore gives an extremely clear, distortion-free image. The stars are perfectly sharp not only in the centre but also at the edge of the field of view.
- multi-coating ensures low internal reflections - separating the closest double stars with these eyepieces is a breeze, and the fine detail on planets emerges clearly.
- the orthoscopic eyepieces in this series are parfocal, i.e. almost no refocusing is needed when switching eyepieces.
Construction of an orthoscopic eyepiece: The optics consist of a plano-convex lens with a triplet, meaning there are only four air/glass surfaces. The interior is comprehensively blackened and effectively suppresses any stray light. In addition, the hard anodized barrel comes with an internal thread for taking filters.
The filters of the ASTF series (AstroSolar Telescope Filters) are ideal for medium to large high-end telescopes: a very good telescope deserves a very good filter!
