APM Zoom Eyepiece 1.25", 7.5 mm- 22.5 mm 1.25" or 2"
Our zoom eyepiece covers a large, and the most important part of the useful magnification range at a lot of telescope focal lengths. This prevents you to constantly change the eyepieces. The advantage: More comfortable work without losing focus, financial savings due to the elimination of many individual eyepieces.
With this eyepiece, we have attached importance to a very good optical quality. When zooming, the edge sharpness, contrast and image correction remains at the same high level. The optical surfaces are carefully coated and the lens edges are of course effectively blackened. Stray light and reflections are reduced to an absolute minimum provided by a special internal baffle system.
An optimization of the viewing position results in stress-free observation, a comfortable viewing position and suitability for glasses wearers, thanks to an AP distance of 20mm.
This eyepiece is very versatile and, due to its quality, also suitable for a wide variety of object groups. It resolves great, offers high contrast and natural colors. Whether planetary observation or deep sky object, you will not miss a single detail.
