Celestron CGX 1100 Telescope

The Celestron CGX 1100 is a telescope which consists of an 11 "optical tube , equipped with one of the best optical treatments on the market, the Star Bright XLT and the new CGX equatorial mount . A device that adapts to the demands highest of the atrophotographers .

11 "(279mm) diameter optical tube, made of aluminum, which incorporates the Star Bright XLT optical treatment, a substantial improvement on the standard multi-coated treatment and that offers better performance in brightness, contrast and color definition. With a 11 "diameter we are already talking about an ideal telescope for deep sky and astrophotography of galaxies and constellations.

The focal length is 2800mm and the focal ratio is f / 10 , physical properties of the optics that make it versatile, for both planetary and astronomical use . It incorporates a 40mm eyepiece with a capacity of up to 70x. The finder is 9 x 50 and the dovetail is also compatible with the CGE mount.
The German Celestron CGX equatorial mount represents an evolution and advancement in equatorial mounts for observation and astrophotography . The new, more compact design is combined with more precise and stable technical adjustments, which improve tracking and hence all the derived observation.

Among these improvements, the new belt drive system stands out, which facilitates the operation of the engine with heavy loads. Improving the engine translates into a smoother turn, especially under heavy loads. The internal gear system, with brass wheels and steel worm bolts, are responsible for reducing friction , and therefore providing more even tracking.
The internal wiring is an important advance since it minimizes its deterioration and also protects it from the elements, the tension of the wiring is avoided with the movement of the mount and the telescope, thus there is no danger of breakage . Internal sensors at the end of the two axes are another interesting safety mechanism , by detecting that the end is reached, preventing the turn from reaching the stop and causing damage to the mount or optical tube. At the same time, these sensors allow you to always restart the movement of the frame from the same starting point, the index position.
In terms of design and ergonomics , the EQ Mount head is adjustable to optimize the center of gravity with respect to the tripod, thus increasing the latitude range from 3º to 65º. In the assembly of the optical tube, it incorporates a "dual-fit" system between dovetail for CG-5, Vixen and CGE. The adjustment of the polar alignment system also presents a notable improvement, with the optional StarSense system being optionally added. For carrying and handling, the two handles are essential for grasping the frame.
Control stick with USB connection, Two AUX accessory ports to support wireless alignment accessories: / Wi-Fi and operation with accessories such as StarSense, AutoAlign and SkyPortal WiFi module (sold separately) USB 2.0 port, used for connect directly to the PC with the included software.
The tripod is stainless steel and powerful enough to withstand 25kg of load . Includes accessory for the eyepiece support or tray, three 1.25 "and two 2". It contributes 20 more on the route outside the meridian, on both sides.
