APM Zoom Eyepiece 1.25"/2" with 7.5 mm until 22.5 mm focal length
Practical 7.5-22.5mm zoom eyepiece for telescopes with 1.25" - or optionally 2" plug-in connection. The zoom function: stepless from low to high magnification
Zoom eyepieces offer the user particularly convenient observation - because with just one eyepiece you can cover a wide range of magnifications. You start at low magnification and increase the magnification simply by turning the ribbed surface on the eyepiece. The observed object always remains in the eye of the observer. It could hardly be more comfortable.
Optical quality: extraordinary sharpness
You will find that the eyepiece is of exceptionally good quality. The optical design allows image sharpness, edge distortion and contrast to be maintained even when "zooming through". This is made possible by a specially calculated aperture system inside the eyepiece and of course by special coatings and blackened lens edges.
Also well suited for eyeglass usersUniversally applicable
Many eyepieces are not necessarily suitable for spectacle wearers. The APM Zoom eyepiece is quite different: with up to 20mm eye relief, you can see the entire field of view even with glasses. There is no need to constantly put on and take off your glasses and no need for uncomfortable focusing. So leave your glasses on when observing and concentrate only on the object of observation.
Even if you do not wear glasses, you will benefit from the large eye relief of the eyepiece. The eyepiece offers a comfortable viewing experience for everyone.
The zoom eyepiece is suitable for all common telescope types. Particularly attractive, however, is its use on ED refractors for planetary and lunar observation. But a zoom eyepiece also has its advantages for deep sky observation. For example, you can use the eyepiece to zoom into a globular cluster and resolve it into individual stars.Note:
