  • Transport case included

TS-Optics hyperboloid Astrograph with 150 mm Aperture and f/2.8


These astrographs are perfectly tailored to the modern demands of the digital astrophotography. In opposite to simple Newtonian telescopes with coma corrector, the TS Hypergraphs have a hyperbolic primary mirrror and an especially designed corrector in the focuser. With this, a perfectly corrected image circle of 45 mm diameter is obtained, with space-optimised design and a moderate secondary mirror with 70 mm 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 features of the TS Hypergraphs at a glance:

  • Optics optimised for astrophotography, with high resolution over the entire useable image field.
  • Carbon tube for a significantly better focus stability than with a metal tube. Refocusing after temperature changes can be omitted. The images become sharper.
  • Secondary mirror is installed with the necessary offset, the illumination of the field is more even.
  • Despite the extreme focal ratio the telescope is well to collimate and it keeps collimation well even during transport.
  • Micro focusing is already built-in, this is necessary with the extreme focal ratio of f/2.8
  • High-quality CNC tube rings and a GP/Q5 dovetail bar are included in the scope of delivery
  • Carry handle with support area for a finder shoe
  • Easy camera adaption via the M48x0,75 connection thread of the focuser. The working distance is 55 mm.

Easy camera connection via the thread of the focuser
When dealing with such a highly resolving and fast optics, a threaded connection of the camera is necessary. In this way, tilting and therefore unsharp stars at the edge are avoided.

The 2.5" R&P focuser has, besides the female M63x0.75 thread, a male M48x0.75 thread. The working distance from this thread is perfectly 55 mm. This matches, for example, exactly the distance which a SLR camera and the matching T-adapter need. Even astro cameras, like the ones from ZWO, are already supplied with an adapter kit to M48 which takes account of exactly this distance.
