Hyperbolic astrograph 150mm - F/2.8

These astrographers are perfectly suited to the modern requirements of digital astrophotography.
Unlike the simple Newtonian telescopes with a coma corrector, hypergraphs have a hyperbolic primary mirror and a corrector specially designed in the carving holder.

With this, a perfectly corrected image circle of 45 mm in diameter is obtained, with an optimized design in terms of space and a moderate secondary mirror of 70 mm in diameter. At the same time, the image quality is so high that even modern Astro cameras with very high resolution can be used.



The advantages and characteristics of hypergraphs at a glance:

  • Optics optimized for astrophotography with high resolution throughout the usable image field.
  • Carbon tube for much better stability of focus than a metal tube. No need to readjust the focus when the temperature changes. The images are clearer.
  • The secondary mirror is integrated with the offset (offset) required, the image field lighting is more uniform.
  • Despite the extreme focal ratio, the telescope is collimative and it maintains collimation during transport.
  • The eye door has been further improved and now allows an even better development. It perfectly maintains the focusing position, even over a long period of time.
  • The double -speed focus is already integrated, which is also necessary with the extreme focal ratio of F/2.8.
  • High quality CNC tube rings and a barrel bar are included.
  • Transport handle with mounting surface for search shoe
  • Easy adaptation of the camera via the M48X0.75 connecting thread of the carriage carrier. The working distance is 55 mm.

Simple adaptation of the camera via the screw of the carriage carrier

With such a resolution and rapid optics, a screwed adaptation of the camera is necessary. This prevents the inclination and therefore the stars blurred on the edge.

The R & P 2.5 "R & P rack has a male thread M48x0.75. The working distance of this thread is exactly 55 mm. This corresponds, for example, exactly the distance required by a reflex camera and the corresponding adapter In T. Astro cameras, such as those of Zwo, are also already provided with an adapter kit for M48, which exactly takes this distance into account.
