Product description

This article is significantly reduced in price!

The reducer has been designed for standard triplet apochromats. It reduces the focal length by 1/4 and increases the light intensity accordingly. Thanks to its large lenses, this reducer is capable of fully illuminating even full-frame sensors.

Connection data:

  • Telescope connection thread: M82x1 thread with adjustment flange
  • Camera-side connection thread: M82x1 internal thread

Distance from camera thread to chip, see connection details:

  • TS APO 115/800mm / APM-LZOS Apo 115/800 ... 76.5mm

  • APM-LZOS 105/650mm ... 80mm
  • APM-LZOS 100/800 mm ... 77.5 mm
  • TS APO 130/780 / APM-LZOS 130/780mm ... 77.4mm
  • Skywatcher Esprit Apo 120 mm ... 77 mm
  • APM-LZOS 152/1200 mm ... 74.2 mm
  • TS APO 150/1000mm and Skywatcher Esprit Apo 150mm ... 77mm

  • GSO / Astrotec RC telescopes from 10" ... 91.2 mm

Required back focus when the reducer is screwed onto the focuser tube: The corrector shifts the focus further in. The reducer has a housing diameter of 90 mm. To sink the reducer into the focuser, the focuser tube must be thicker than 90 mm, such as all 3.5" Feather Touch focusers from Starlight Instruments. Then you will definitely have no problems finding the focus. However, if the reducer is screwed onto the focuser tube, you will need about 210 mm of back focus from the connection thread of your focuser. If you do not necessarily want to go full frame, the smaller reducer is an alternative.
