This Newtonian reflector is optimized by fast focal ratio of f / 4 for astrophotography and widefield observation.
The large-sized secondary mirror and the quality Okularauszug guarantee optimum illumination of the visual field in photography and also in monitoring. In the design of the reflector value was placed on high stability and rigidity.
The benefits at a glance:
The reflector is optimized for a very good illumination. The diameter of the front bezel is generously sized, so that the tube does not shade itself. Also, the secondary mirror guarantees an image free from disturbing shading, even when using large format camera Senoren.
