Celestron CGEM 1100 HD

Celestron CGEM 1100 HD
The Celestron CGEM 1100 HD is part of the Celestron CGEM HD series which is the advanced version of the CGEM series. The telescopes of the CGEM HD series are unique in that they have absolutely no chromatic aberration; the light is sent in equal frequencies to the mirrors and eyepiece, making the image sharper because of the absence of colour dispersion. Furthermore, the HD version uses mirror locks to keep the mirrors on the right spot so the image remains stable. The result is an image that is almost three times sharper than that of a standard Schmidt-Cassegrain telescope. The Celestron CGEM HD series may therefore rightly be called "HD".

Celestron CGEM 1100 HD
The catadioptric Celestron CGEM 1100 HD telescope with equatorial mount has been ergonomically designed and has a fresh, bold and attractive appearance. The mount is suitable for astrophotography as well as for "normal" observations. The Celestron CGEM 1100 HD telescope is the top model of the CGEM HD series. The Celestron CGEM 1100 HD telescope comes with NexRemote software for the telescope which is to be used in combination with your PC. Moreover, the telescope is easy to (dis)assemble and transport. The telescope has a 2800mm focal length and this is why it is ideal for deep-sky observations.

Mirrors and Coating
The Celestron CGEM 1100 HD telescope has a primary mirror with a diameter of 280mm. The mirror has the unique Celestron Starbright coating; this coating ensures that the mirror is stronger and reflects more light. Also, it renders the surface of the mirror more even and directs the light more accurately to the secondary mirror. The coating consists of several layers: Celestron have used aluminium, titanium and magnesium.

CGEM database GoTo
The database of the Celestron CGEM 1100 HD telescope contains over 40,000 celestial objects including Messier objects, the Caldwell Catalog, NGC systems, nebulae and planets. A special identification feature tells you where to look, but you can also take a tour through the sky. For example: point the telescope somewhere, let it identify the Messier objects and the CGEM 1100 HD will automatically show the five nearest objects; that’s GoTo at its best. The GoTo is easy to operate with the included remote control that has a bright LCD display.

Alignment
The Celestron CGEM 1100 HD telescope features a revolutionary alignment method: All-Star Polar Alignment. Using the software you align the telescope by selecting a bright star; alignment is possible even without seeing the North Star.
