Celestron Omni XLT 120mm Refractor EQ

Omni XLT series features the stable platform of the CG-4 mount and high quality optics. Using aspheric shaping technology in conjunction with hand-figuring the optics the Omni XLT presents an image with virtually no spherical abberation. We also added our famous StarBright XLT coating system to further enhance light transmission.
