TS-Photon 8" f/6 Planetary Newtonian for visual observation and planetary photography
This telescope of the PHOTON series is a TOP choice for committed observers and photographers of the moon and planets. This Newtonian is optimized for exactly that purpose and delivers best possible performance. Nebulae, star clusters and galaxies can also be observed. Enjoy pinpoint stars across the entire field of view!

An uncompromising, stunning image quality, comparable to a 150 mm apo, is achieved by a hand selected primary mirror made of fused quartz and by a small secondary mirror with 50 mm diameter.

The advantages of our PHOTON series in summary:
Optimal sharpness of moon and planets
With only 10 kg weight this telescope is still transportable and can be operated with fairly small mounts
Linear obstruction only 25%; anyhow very good illumination, even with 2" eyepieces
Due to the f-ratio f/6 one achieves great sharpness across the whole field of view, even with expensive wide-field eyepieces
Rigid 2" Crayford focuser with 1:10 micro gear reduction for precise focusing and 1.25" reduction
Steel tube and mirror holders made of metal, allowing optimal collimation stability
Only with TS: Optional Carbon tube for increased rigidity


The mirror´s material fused quartz:

Every material has its respective thermal expansion coefficient. This value determines how the mirror reacts when temperature changes. The lower this coefficient, the less the mirror reacts to these temperature changes. This means faster readiness for use and higher image quality in general.

A mirror made of fused quartz has no significant thermal expansion, making it superior to most other mirror materials like Pyrex or Suprax, similar to Zerodur. We recommend mirror made of fused quartz because of its excellent surface for the contruction of high resolution Newtonian telescopes for observation of moon and planets.

Astrophotography with the TS-PHOTON 8" f/6 Newtonian:

The telescope is optimized for visual observation and for photography of moon and planets. The focus position of 40 mm is ideal planetary cameras.

With astro cameras, for example from ZWO, you can get into focus without any problems. A coma corrector is not necessary up to a sensor size of about 20 mm diameter. The combination with the new ZWO ASI533MC-P and this f/6 Newtonian allows exciting deep-sky images with high resolution, without corrections. Even infrared photography is possible.

DSLR cameras on the other hand require a converter that shifts the focal plane outwards. With the photo-visual 2" Barlow lens + Foto converter TSB22 you achieve exactly that.
