Product description

More about the series Photon...

The N 203/800 optics are incredibly high-speed and, therefore, ideally suited to astrophotography! You require a significantly shorter exposure time comparted to a system with a higher focal length. With its optional coma corrector, this Newtonian turns into an real astrograph.

Due to its design, the Newtonian telescope produces images with no colour errors. Unlike other telescope designs, where a lot of money needs to be invested in the lenses to minimise these errors.

With an 8 inch (approx. 203 millimetre) aperture, visual observations of nebulae and galaxies are a great pleasure too. The supplied extension tubes ensure the ability to reach the correct focal position.

An integrated fan provides fast cooling to the ambient temperature.

An 8-inch model is also still relatively easy to transport and only requires a medium-sized mount.

The working distance from the M48 thread is 55 mm. Using a T-ring automatically sets the correct distance for astrophotography using DSLR cameras.

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.
