Kson 102mm / 900mm f/9 Optical Tube Assembly with 1.25″ Focuser


The Kson 102mm achromatic refractor in a amazing f/9 focal ratio is outfitted for great performance.  Images are brighter than with a 80mm refractor, with better resolution and slightly better viewing of planets and double stars while still remaining very portable. Its general nature makes it a great choice for viewing planetary objects such as Jupiter, Saturn and the Moon as well as many deep sky targets including star clusters, and its portable size makes it easy to bring along on trips to dark skies.

The doublet objective lens is multi-coated for excellent light transmission, and the build quality is excellent with a ‘made for life’ philosophy – an all metal tube with no plastic parts – even the dew cap is metal.
