Quintuplet apochromat, flat field and 4" focuser

What is it that drives astrophotographers time and again? It is the fascination of depicting the sky in its most beautiful colours and shapes. This quintuplet apochromat does the job beautifully. A triplet lens with ED glass, an integrated flattener and a 4" focuser will ensure successful astrophotography.

The highlights at a glance:

  • 121mm quintuplet ED-Apo with five lenses for incredibly beautiful astrophotos
  • A two-lens integrated corrector that provides complete illumination of your full-frame camera with an image circle diameter of 49mm.
  • 4" focuser with a 1:10 reduction ratio: Easily focus larger and heavier cameras with high precision
  • Camera rotates 360° so you can find the right orientation
  • 82mm thread for a permanently secure connection
  • M48x0.75 camera adapter included in scope of delivery

Why these optics reveal more details
No more images without contrast. This apochromat shows what is really possible: pure-colour and high-contrast observations and astrophotos. The key 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 when observing the planets, for example. All surfaces of the lens elements are treated with an effective multi-coating to prevent reflections. Enjoy memorable observations and shots.

Large focuser with gearing and ball bearings

Full-frame enthusiasts need space: That is precisely what the geared focuser offers. It beautifully complements the premium optics and produces great illumination and images without shading. Hybrid Crayford and gear technology combines perfectly smooth focusing with high load-bearing capacity. A 1:10 reduction gearing makes precise focusing a breeze. Astrophotographers around the world value precisely these features.

360° rotation for framing the perfect photo.
You found the object and focused on it, but with the wrong orientation? Save yourself the trouble of having to start over again at night to align an elongated object with the sensor. This is easy to do in seconds thanks to the 360° rotating focuser.

A strong connection
Nothing will slip out of place again: The integrated thread provides you with the option of securely mounting your accessories. For example, take your full-frame optimised off-axis guider and fasten it as if it were a permanent part of your new telescope.

CNC tube designed for the best optics
The tube of the Omegon Apo consists of a CNC machined metal construction with a sophisticated anti-reflective aperture system. The entire tube is lined with a velvet-like, black fabric.

Extending and fixing the dew cap
The Apo's dew cap can be extended and fixed with a screw. It can be retracted for transport.
