Product description

Full-featured apochromatic refractor combined with the convenient operation of a telephoto lens. The requirements of astrophotographers were taken into account in particular.

  • The optics are a 4-element apo with two ED special glass elements for the best possible colour correction. An additional 2-element corrector is permanently built into the tube and guarantees a distortion-free field up to full format.
  • In addition to normal focusing for landscape photography, microfocusing is also available at the front end of the apochromatic refractor. You can focus with an accuracy of 0.002 millimetres and then fix the optimal focus position.
  • The Apo has an M48x0.75 connection thread on the camera side with a working distance of 55 millimetres to the camera. This allows you to connect all common cameras with the appropriate T-ring.
  • In addition, the Apo has an M69x1 internal thread with a working distance of 66.5 millimetres.

Of course, you can also use the Apo without restriction for landscape and animal photography. The results will inspire you.

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.
