Newtonian astrograph, 200 mm and f/3.2, by Omegon

This compact and portable Newtonian astrophotographer is designed for the demanding astrophotographer looking for a fast telescope with very good sharpness over a large field of view. It is designed for modern high-resolution and large diameter sensors, up to full format.

Thanks to its fast focal ratio of f/3.2 it can take very deep images of deep sky objects in a single night, with very high resolution. Thus, it is possible to obtain images of extended nebulae or galaxy clusters.

A summary of the advantages:

  • parabolic main mirror with 200 mm aperture and f/3.2
  • 3" corrector integrated into the focuser with 0.85 reduction
  • 90 mm diameter secondary mirror (minor axis) for full illumination up to full format
  • large 3" rack and pinion focuser with reducer and M48 adapter
  • possibility of tilting the focuser
  • Adjustable and stable support for the main and secondary mirror
  • 44mm diameter fully illuminated and corrected field of view
  • 55mm working distance from M48x0.75 thread.
