More information
Our APM Super-Zoom eyepiece is a modern new development for universal use during the day and in the night sky. Great emphasis was placed on excellent optical and mechanical quality as well as optimized ergonomics. The completely re-calculated optics show excellent resolution and contrast values as well as a sharp image at a large apparent field of view.
The conical eye shape, the slim body, the high eye relief and the integrated thread for the Tele Vue Dioptrix , make this APM Super Zoom the ideal zoom eyepiece for binocular observation.

There is almost no need to refocus when changing magnification. You can now zoom in on your favorite objects without losing image quality. The wide focal length range allows the use on very many instruments, whether on a compact Apo or on a large Dobsonian.
We have also tested this eyepiece on a 20" F/3.6 Dobsonian, and it has shown an impressive performance up to the edge. That means we recommend this eyepiece also for very fast Newtonian/Dobsonian telescopes.


All optical components are of course modern multi-coated, blackened lens edges go without saying. The pupil distance (eye relief) is between 18 and 20mm, so it is very user-friendly. The maximum Ø of 56mm also allows the use on a binocular attachment.

Our APM Super-Zoom eyepiece is an optical top product at an excellent price, which does not have to hide behind much more expensive zoom eyepieces!

Focus position: Reference Tele Vue Ethos 13 mm...the APM Super Zoom must be moved 12 mm further in.

Excellent Zoom eyepiece and great range of focal lengths!! A rare find these days!

I got this just recently. First light in my 152mm refractor had the scope offering up a lot of contrast and the eyepiece was sharp to the edges!

Two things I really like about this eyepiece:

1) parfocal (or very close to it) and constant FOV across the zoom range - only zoom on the market that does BOTH, exc. the Nagler planetaries, but these are very short focal lengths and also 50 degree FOV. (nice but the extra field is VERY nice indeed!)

2) VERY smooth action on the zoom - even at -6C for >2h... adjustment was smooth, never stiff, and also the "clicks" for the specific focal settings was just enough to permit knowing where you are without having to look, and also subtle enough to allow the zoom to work without having to torque it.

The service from David B and his team was excellent, as always. I was informed when it was available and they shipped the next day. Came 3 days later 3/4 across the country! (Canada) - great job David! Thanks again for all the superb service.
