Celestron CGEM II 1100HD Computerized 11″ f/10 EdgeHD Telescope 12019

Description

To make a casual polar alignment for visual use quick and easy, there’s a latitude scale with large ergonomically-friendly altitude and azimuth adjustment knobs. A unique Celestron All-Star Polar Alignment program built into the NexStar hand control helps you do a very precise computerized polar alignment in mere minutes, using any bright star, even when Polaris is hidden by trees or buildings. The program works in both northern and southern hemispheres.

Adjustable height tripod: The tripod has 2″diameter stainless steel legs with a metal center leg brace for rigidity, for excellent vibration damping characteristics. The tripod also includes graduated markings on the tripod legs that will assist in quickly leveling the instrument. The center leg brace is drilled to form a convenient accessory tray that holds 1.25″ and 2″ eyepiece to keep them up out of the dew-soaked grass.

Mounting the scope: New for the CGEM II mount is a dual saddle plate. The saddle plate will now accept both the CGE/Losmandy wide dovetail plate as well as the AVX/Vixen style dovetail plate. The dovetail slot on the top of the mount holds the long dovetail slide bar mounted under the optical tube. This allows you to slide the optical tube fore and aft in the dovetail slot to quickly and precisely balance the optical tube in declination when you add or subtract accessories, eliminating the need for an extra counterweight to balance a camera or other accessories. Setup and take down times are exceptionally fast, as a single large hand-tighten knob holds the optical tube in place. A second lock knob prevents the tube from sliding off the mount should the hand-tighten knob loosen. The oversized dovetail mounting platform assures secure vibration-free tube attachment.

Balancing the scope: The two sliding 17pound counterweights are locked in place on the counterweight shaft with asingle large hand-tighten knob each. This makes it easy to rebalance the scope in right ascension if you add heavy photographic accessories.

NexStar computer hand control: The supplied NexStar computer hand control has a built-in database of more than 40,000 stars and objects that it can find and track for you. These include the complete RNGC, Messier, Caldwell, IC, and Abell catalogs; selected SAO stars; the planets, the Moon, and others. The custom database lists of all the most famous deep-sky objects by name and catalog number; the most beautiful double, triple and quadruple stars; variable stars; non-planetary solar systems objects; and asterisms.

TheNexStar display: All of the database and scope operation information is displayed on a double line,16-character, liquid crystal display on the hand control. There are 19 fiber optic backlit LED buttons to make it easy for you to control the computer without affecting your dark-adapted vision. The NexStar hand control provides a constant and easily-visible illuminated right ascension and declination readout of the scopes position on the sky. This provides much greater accuracy than conventional (and hard to see at night) manual setting circles for star-hopping or locating objects by their celestial coordinates alone, should you want to observe the old-fashioned way without using the computer to find objects for you.

SomeNexStar features: New for the CGEM II mount, a USB 2.0 communication port on the hand control allows you to operate the telescope via a personal computer using a USB cable and NexRemote software CD-ROM. The hand control and motor control software is flash-upgradeable to allow you to download the latest product updates over the Internet to keep your CGEM II mount always at the cutting edge of technology. An autoguider port is located on the electronic pier for guided, but unattended, long exposure astrophotography.

Aligningon the sky: Five different alignment methods are built into the NexStar computer – 2-star align, quick align, 1-star align, last alignment, and solar align – allowing you to choose a level of computer accuracy in automatically finding objects with which you are comfortable. Alignment is easily accomplished in only a few short minutes. You can be observing in less than 15 minutes after you first take the scope outdoors. There’s even a new and unique “All-Star” software-assisted alignment of the mount’s polar axis using a single bright star that will have you ready for imaging before it’s even dark enough to see the North Star.

Two-year warranty: All Celestron go-to telescopes have a two-year warranty.
