The Equinox 100 departs slightly from the other refractors in this series. It is designed primarily as a visual instrument for high-power, high-resolution applications. The Equinox 100 features a beautifully corrected ED doublet with a focal length of 900 mm.

    It provides outstanding views of solar system objects and of brighter DSOs, and can split even the tightest doubles with ease. For added fun, attach a video camera along with our 2” ED 2x Barlow and treat yourself to stunning real-time views of earth’s nearest neighbors!
