This Newtonian reflector is optimised for astrophotography and wide-angle observation due to its fast f/4 aperture ratio.

The large secondary mirror and high-quality focuser guarantee optimal visual field illumination for photography and observation. Emphasis was placed on high stability and rigidity during construction.

The advantages at a glance:

  • fast and diffraction limited optics and f/4 for short exposure times
  • 94% forced reflection on the primary and secondary mirrors
  • High-quality focuser, even for heavy cameras
  • built-in primary mirror refrigeration for fast telescope cooling
  • comfortable focus position – also allows DSLR camera use; Off-axis guider

The reflector is optimised for excellent illumination. The front aperture has a large diameter so that the lens tube does not overshadow it. The secondary mirror also guarantees a picture free from annoying shadows, even when using large camera sensors.

It is not only important which telescope you buy, but also where you buy it.
