APO 180 f/7 Fluorit Apochromat


It could be counted as largest portable telescope. It fits in any car and could be lifted and installed on the mount by one person. Same excellent color correction as in APO160FL.

The APO 180 has number of features that in a given combination are rarely found in one scope:

  • Precision apochromatic objective with modern coating that makes lenses almost invisible.
  • Retractable Dew Shield.
  • Light weight tube assembly.
  • FeatherTouch 360° rotatable focuser with coarse and fine focusing
  • Collet type eyepiece holder
  • Precision tube rings with adjustable latches


The advantages of Fluriot to ED glass: less adsorption or rather more transmission

This Reducer/Corrector reduces the focal length of the 180 FL from 1.260 mm to 900 mm and gives you a focal ratio of f/5. For a full frame camera (24 x 36 mm), this results in a field of view of 1.5 x 2.3 degree at an image circle of 50 mm, diffraction limited and free of vignetting.
