    Celestron CGEM II 925 EdgeHD Telescope

    The Celestron CGEM II 925 EdgeHD Telescope integrates the CGEM II Computerized Equatorial mount with EdgeHD optical system. This versatile combination gives you one of the most powerful star gazing instruments and astro-imaging telescope.

    The EdgeHD optical system combines the compact power of the Schmidt-Cassegrain design that comes with an improved high-definition optical system and high quality wide field images. Astrophotographers will be able to see aberration free images across CCD or DSLR cameras. With this optical system, an extremely flat focal plane is precise enough to match the strict tolerances of most large commercial CCD sensors. Stars will be in tight focus even at the very edge of the chip. EdgeHD optics also produce diffraction limited stars on axis and maintains diffraction limited stars across the entire field of view of many of the most popular astrophotography cameras.

    The CGEM II Computerized Equatorial mount is the other half of the equation. It brings stability, slewing speed and accuracy to the table. It also boasts of improved software that consistently maintains accuracy and a huge database of over 40,000 celestial objects. The mount is sturdily designed to dampen vibrations which interfere with observation. It delivers these capabilities even when handling the largest 11” optical tubes. Large Altitude and Azimuth adjustment knobs allows quick and easy polar adjustment alignment. The All-Star polar alignment process and the Permanent Periodic Error Correction features allow users to maintain slewing accuracy and alignment overtime. As part of its improved design, uninterrupted Meridian (imaginary line passing from North to South) tracking is now possible on this mount.
