Product description

More about the series Pro Astrograph...

Omegon 200mm f/3.2 Newtonian Astrograph

The compact and portable Newtonian Astrograph has been developed for the dedicated astrophotographer who wants a powerful telescope with very good sharpness over a large field of view. The Astrograph has been developed for modern sensors with high resolution and large diameters up to full format.

The extremely fast aperture ratio of f/3.2 allows you to take very deep shots of deep-sky objects in just one night, while maintaining very high magnification. Images of extended nebula objects or galaxy clusters are thus possible.

The highlights at a glance:

  • Parabolic primary mirror with a 200mm, f/3.2 aperture
  • 3" corrector with 0.85 reduction built into the focuser
  • 90mm diameter secondary mirror (minor axis) for full illumination up to full format
  • Large 3" rack and pinion focuser with reduction and M48 adapter
  • Tilting possibility at the focuser
  • Adjustable and stable holder for primary mirror and secondary mirror
  • Fully illuminated and corrected image field of 44mm diameter
  • Working distance of 55mm from the M48x0.75 thread

Customer reviews

There are some issues...

Review by lkrustev on 26.08.2021 16:59:30

( 3 / 5 )

On first glance the build quality is great, but there are some issues:

- The mirror cell is an open one, so the mirror is not fixed in forward direction, so it shifts when the scope moves, and it is losing collimation all the time even during the imaging session.
- The secondary mirror is glued to the holder without too much precision, so when you align it, it is not centered, which is unfixable.

... I've tried all possible methods for collimation /many times/ and still the stars are far from perfect.
