Omegon Apochromatic Refractor Pro APO AP 61/335 ED OTA + Test Protocol

Omegon Apochromatic Refractor Pro APO AP 61/335 ED OTA + Test Protocol
This telescope comes with individual optical test protocol!



Mobile at home or for travel. Always great images

On a mountain or in the desert. Outstanding nights also need an outstanding telescope. But good conditions are not to be found everywhere. This small apochromat has such narrow dimensions that it can accompany you to any place with a good sky. This makes good astrophotography even more mobile.

The advantages at a glance:

61mm Duplet ED APO with two lenses for a color-pure image with good contrast.
Retractable dew cap for easy transport
2.5" focuser with 1:10 reduction: even larger and heavier cameras can be focused smoothly and with high precision.
Camera can be rotated 360° to help you find the right alignment
Vixen-type finder shoe so you can easily mount any finder scope
Why this optic shows more detail
Put an end to images without contrast. The Apochromat shows what is really possible: pure color and high contrast observations and astrophotos. The reason is a sophisticated optical design with premium ED glass for a crystal clear image. Compared to most mirror systems, the better defined optics allow you to see more and finer details in planetary observations, for example. The lens elements have been provided with an effective muli-coating against reflections on all surfaces. Look forward to observations and images that will be remembered.

2.5" gear-driven focuser with ball bearings
Almost a true space miracle, the 2.5" gear focuser is large enough, no shadowing occurs. An ingenious hybrid technique of Crayford and gear makes it especially powerful and suitable for accessories up to 4kg. In addition, it can be focused silky smooth via the ball bearings, so you can easily find the perfect focus. A 1:10 reduction for finest corrections completes this focuser. These are exactly the features that astrophotographers around the world appreciate.



CNC tube for one of the best optics
The tube of the Omegon Apo consists of a CNC machined metal construction with a sophisticated aperture system against reflections. The entire tube has been lined with a velvet-like black fabric.

Extend and fix the dew cap
The Apo's dew cap is extendable and fixable with a screw. It can be retracted for transport.
