Introducing Celestron's bold, new CGEM series computerized telescope. The clean and modern appearance highlights Celestron's commitment to providing instruments for today's serious enthusiasts.
Already a pioneer in the manufacture of high-quality low-cost Schmidt-Cassegrain telescopes, Celestron continues to dazzle customers with its new Aplanatic Schmidt-Cassegrain optics, nicknamed "EdgeHD", which virtually eliminates Coma abberation. Stars will appear pin-point from edge to edge.
Flexible photographic options, such as prime-focus, eyepiece projection, focal reducers/field flatteners, and piggyback mounts, coupled with the robust CGEM equatorial mount, will take your hobby to the next level.
The CGEM mount delivers improved tracking, using high-quality gears, drives and bearings, permanent periodic error correction, and tracks well past the meridian (the best part of the sky).
The 40lbs payload capacity of this mount coupled with the 80mm (3") dovetail saddle means you can add a guidescope without overloading the mount.
Celestron is known for innovation, and they continue this tradition with the new "All-Star" polar alignment that does away with the polar finder.
- Start with a rough polar alignment
- Perform a two-star alignment and add one calibration star
- Select "Align Mount"
- Locate and centre a bright star, preferably high up near the meridian, away from the Zenith, Celestial Pole or E/W horizon
- Locate the same star in the database
- Centre the star in a reticule eyepiece, using the mounts azimuth and latitude adjustments
- Update the computer star alignment
Features
- EdgeHD optics yield pin-point stars from edge-to-edge with no coma
