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 aberration. We also added our famous StarBright XLT coating system to further enhance light transmission.



High quality optics start with each lens and(or) mirror being hand selected so only the finest grade of optical glass is used

StarBright XLT coatings provide maximized light transmission
