TEC APO 160 f/7 Fluorit Apochromat

APO160FL - is the next step in size after APO140ED, keep in mind there is quite a difference in price here for the improvements in color correction. This scope by style is a scaled version of the APO14O, but of different optical design, is slightly longer and heavier, and may require a larger mount. APO160FL has excellent color correction thanks to glass combined with Fluorite as a middle element

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

APO 160 FL Apochromat vs. APO 140 ED

The APO 160 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

Recommended 0.72x Telecompressor Corrector # 140 5372 of Astro Physics

This Reducer/Corrector reduces the focal length of the 160 FL from 1.120 mm to 800 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 1.7 x 2.6 degree at an image circle of 50 mm, diffraction limited and free of vignetting.
