The focal ratio of a telescope is a very important factor that determines what type of viewing the optical tube is suited for. Generally speaking, faster focal ratios like f/2 are better for deep sky observing and faster imaging while slower focal ratios like f/11 tend to be better for observing planets. Catadioptric designs such as Schmidt-Cassegrains use aspects from both reflectors and refractors and by default have a slow focal ratio in a shorter sized optical tube. However, they're also compatible with many accessories that can adapt the optical tube for better deep sky viewing and imaging. In the case of the Celestron CGEM DX 1400 FASTAR Schmidt-Cassegrain Computerized Telescope, a built in feature called the FASTAR system consists of a removable secondary mirror that turn the focal ratio from f/11 to f/2! This makes imaging with larger CCD sensors better for bigger pixels and results in faster exposure times.

The smaller cousin to the CGE Pro, the Celestron CGEM DX Equatorial Mount features many of the basic CGE Pro mechanics such as slewing capacity and All-Star alignment. It is great for both visual astronomers and astro-imagers alike. With a payload of 50 Ibs, the majority of larger end optical tubes can be supported on this mount. The CGEM DX is quite easy to set up and the observer can get it properly aligned and tracking pretty quickly with the All-Star Polar Alignment method. This setup gets the mount aligned properly to the north celestial pole by slewing to a bright star and giving the observance reference how to adjust the altitude and azimuth accordingly. With a maximum slewing rate of over 5°/per second, the amount of objects the observer will be able to look at in a stargazing period with be outstanding!

The CGEM DX Equatorial Mount uses the NexStar hand controller which has a 40,000 object database with information on over 200 of them. This includes the deep sky objects such as the Messier and NGC as well as solar system objects like the planets and moon. The mount’s internal motors are built with optical encoders, required for low speed tracking. The user can also run their mount through their PC using the supplied RS-232 connection port on the hand controller. To turn this mount GPS compatible, it is highly recommended the optional SkySync GPS Accessory be used in conjunction with the CGEM DX.
