Product description

More about the series Photon...

The 2” Crayford focuser with micro-reduction: The focuser is an essential part of the telescope. It should facilitate delicate focusing and also hold heavy equipment. This telescope's focuser is a high-precision Crayford focuser with micro-reduction and robust ball bearings. This facilitates smooth adjustments, even when carrying loads upwards of 3kg.

Positioning accuracy is less than 0.08mm. This level of precision is sufficient to find the exact focal point even with high-resolution sensors and to get the most out of your optics.

TS Optics is a brand of Teleskop-Service.

It not only matters which telescope you buy but also where you buy it. Our additional services:

  • We are a leading telescope dealer and know the devices we sell. Our customer service team will gladly help you after your purchase if you have problems with assembly or operation.
  • We provide a copy of the 80-page Telescope ABC beginners handbook with every telescope.
  • We also provide an edition of the exciting astronomy magazine, “Sterne und Weltraum” with each telescope.
