Why this optic shows more detail
Put an end to images without contrast. The Apochromat shows what is really possible: pure colour 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 when observing planets, for example. The lens elements have been provided with an effective multi-coating against reflections on all surfaces. Look forward to observations and images that will remain in your memory.

Large gear eyepiece focuser with ball bearings
Full-frame fans need space: this is exactly what the eyepiece focuser in gear design offers. It complements this premium optic beautifully and offers you great illumination and images without shadowing. The hybrid technology of Crayford and gear wheel makes it very smooth-running on the one hand and incredibly powerful on the other. A 1:10 reduction for the finest corrections rounds off this focuser. It is precisely these features that astrophotographers all over the world appreciate.

360° rotation for the perfect image detail
Object found and focused, but misaligned? At night, you should save yourself the trouble of starting all over again and aligning an elongated object to fit the sensor. The 360° rotatable extension makes this task easy, as it is done in seconds.

A firm connection
Nothing will ever get jammed here again: the integrated thread offers you the possibility to firmly connect your accessories. For example, take your off-axis guider optimised for full-frame format and screw it in place - as if it were a permanent part of your new telescope.

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 complete tube has been lined with a velvet-like black fabric.

Extend and fix the dew cap
