Kson “Olympus” AS102 (102mm/1200mm f/12) refractor
The Kson Olympus AS102 is a f/12 classic air spaced (“AS”), crown and flint doublet achromat refractor with a 102mm and a generous f/12 (f/15 with aperture cap) focal length.
Designed for the pure pleasure of visual planetary, lunar, double star and some DSO viewing, this extraordinary achromat is one of the longest focal length modern achromats currently made, designed for getting up close and personal with extraordinary contrast and clarity – without the hefty ‘ED’ pricetag.
Olympus AS102 – A 102mm (4 inch) f/12 configuration with some serious tricks, unusual features and inclusions up it’s sleeve.
The Olympus is designed for the pure pleasure of visual planetary, lunar, double star and DSO viewing, this extraordinary achromat is one of the longest focal length modern achromats currently made, designed for getting up close and personal.

What’s this about being especially suitable for binoviewers?
Binoviewers are remarkable devices that look like a binocular, but attach into your telescope, allowing you to use both eyes (stereo) for viewing. The Kson Olympus was designed from the ground up to be highly compatible with binoviewers. This means that usually, you will NOT need to use an optical corrector, or barlow to make use of them, allowing improved viewing quality, a greater range of compatible eyepieces, and a wider view that would be otherwise possible. They provide a stunning experience with this particular telescope.
We recommend the Celestron #93691 Stereo Binocular Viewer, coupled with some lightweight eyepieces to get started with binoviewing.
