Celestron CGX 1100 HD Telescope

Computerized telescope or GO-TO , which combines the highest optical quality of HD technology with the German CGX equatorial mount . This equipment is designed for the most demanding observers and astrophotographers , who are looking for a product with the maximum possible light transmission and with zero chromatic aberration.

The 11 "or 280mm optical tube incorporates the StarBright XLT optical treatment that Celestron applies to its most advanced range telescopes. This special treatment is combined with the coma-free aplanatic edge HD treatment. This optical tube gives you 800 times more light that vision with the naked eye, thus becomes an indispensable tool for observation and astrophotography.

The entire visual and photographic field is free of chromatic aberrations up to the very edge of the optics. EdgeHD optics produce a focal plane three times flatter than a standard Schmidt-Cassegrain telescope and dramatically flatter than competitive non-coma designs. This ensures that you can see and photograph the stars within the field of CCD sensors . With Celestron's StarBright XLT optical coatings on all surfaces, EdgeHD optics provide you with maximum light performance across the widest photographic and visual spectrum.
The f / 10 focal ratio gives you the necessary scale for deep sky photography and observation, if you want to further expand your field of view you can optionally add the focal reducer designed for Edge HD optics. In taking long-exposure images, the telescope incorporates an automatic adjustment and tensioning system for the mirrors, thus keeping the image centered on the eyepiece.
It includes a high - end eyepiece Celestron Luminos 23mm 2 lace. "Likewise also incorporates 9x50 finder.
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.
