APM – LZOS Telescope Refractor 130 mm f/780 mm with 3.7″ focuser

APM-LZOS 3-Lenses SuperED with APM 3.7 inch Deluxe focuser – in a brand new design!

For many years, we have been producing and distributing high end refractors for science, research, public institutions and dedicated amateur astronomers worldwide.
The optics calculated by us be performed the highest quality standards. Likewise, the mechanical components, such as tubes, lens holders and focusers are manufactured to perfection.

To make APM’s high-quality apochromats with the world-class 3-Lenses SuperED Apo optics more attractive, we have decided to offer an APM / LZOS-APO special edition at a  lower price. This is made possible by our new, built-in APM 3.7 Rack and Pinion Focuser.
This all pays off for our demanding customers.


Optics: Our LZOS Super ED 3-Lenses are delivered with test protocol, Each optic is individually measured with a Zygo interferometer and logged with the serial number of the Opic.

Maximum Strehl (as with the Zeiss APQ) is guaranteed at 95% or better

The tube: Well-known APM construction with fast cool down  tubes

APM 3.7″ Rack and Pinion Deluxe Focuser: The new 3,7″ focuser is a Rack and Pinion type, with 1:10 focusing. It remains rigid under high loads making it suitable for imaging. The attention to detail extends to areas like the 2″ and 1.25″ eyepiece adapters. These use a new design of collar clamp, far superior to the common brass compression rings found on lesser designs. Also new is our 2″ APM  Fast Lock adapter now.
