... a perfect APO with color-pure image - for transportable astronomy at a high level


Illustration with eyepieces (optional)


The ED 81 can not be compared to the typical Chinese apos, neither from the look nor the equipment. The Japanese look trumps by a practically pure color picture. According to the manufacturer, it even outshines the three-liners Apos.

You will perceive even at magnifications of well over 100 times no disturbing color error more. Let yourself be surprised what 81mm opening can show everything on the moon and planets. Especially on the moon will inspire the pure color optics, take fine shades of gray and they follow gossamer grooves. Where the shadow begins on the moon, you will have a hard edge, just as in reality.

Summary observations:

The Okularauszug is not a simple 2 "extract, the free inner diameter is significantly larger - about 60mm! This guarantees optimal illumination to the edge.With our 2" kit (see "recommended accessories") you can see a sky area of ​​about 4 ° That's about 8x the size of the full moon. And that with needle-sharp stars to the edge.
Astrophotography:

A prime discipline for the ED 81 .. there are a few valid reasons why the ED 81 is clearly superior to other devices:

- Okularauszug with about 60mm free opening - no shading by tightly sized 2 "tubes

- A perfectly working flattener for the ED, which is screwed directly to the M60 thread of the pullout and reduces the focal length to 419mm - with bright f / 5,2 !!

- A unique solution - an Off Axis Guider that allows tracking and recording at the same time. The required distances from the Flattener are maintained.

This makes the solution really compact - no separate guide tube is needed anymore !!
