The Celestron Labs S20 is the perfect introductory stereo microscope offered at an economical price.

Although known as the astronomical ring, it is principally employed as an ecuatorial solar universal quadrant.

Allows shortest exposure times, mainly used for digital videography and the lucky imaging technique, and thus almost "freezes" turbulences in the earths atmosphere.

The BAADER Fringe-Killer Filter minimizes unwanted blue fringing, comparable to a Minus-Violet-Filter, while retaining a very pleasing colour balance.

This economical eight-piece eyepiece and filter accessory kit enhances the performance of your Celestron AstroMaster.
