Celestron NexStar 114 GT Telescopes 31142 NextStar

The NexStar - GT series of Telescopes shares a common heritage in features and function. Each NexStar telescope includes the latest state-of-the-art computerized GoTo technology, amazingly easy-to-use features and ready-to-use components. After the computer guides you through a simple set up, each Celestron Nex Star Telescope will point itself to the object you choose from its stored database of astronomical objects without referring to star charts!

To assist in the star alignment, the NexStar uses a lightweight StarPointer Finderscope. The StarPointer is the quickest and easiest way to point your telescope exactly to the desired object in the sky. It's like having a laser pointer that you can shine directly onto the night sky. No need to worry about the inverted images you see through traditional finders, just align the red dot seen through the StarPointer with the desired star in the sky. It's that easy.

With the NexStar's ergonomically designed hand control, the user is free to remove the hand control from its holder for remote use or leave it cradled for hands-free operation. With a touch of a button you can select the object catalog, change the slew speed, view fascinating information about an object, or simply know if a desired object is visible in the sky.

The NexStar GT's deluxe features combine with Celestron's uncompromising optical standards to give amateur astronomers one of the most sophisticated and easy to use telescopes available on the market today.

Celestron NexStar 114 GT Telescope has over twice the light-gathering power of an 80mm telescope! Compact in design, with images bright enough to reveal the polar ice caps on Mars or the cloud belts on Jupiter. View the details of the lunar surface. The rings of Saturn are clearly visible. With the extra light gathering capability of NexStar-114GT, a number of the Messier objects such as the globular cluster in Hercules (M13), or the Great Nebula in Orion (M42) are available to you. Begin to explore some of the fainter Messier objects using the additional light-gathering capabilities of the Nexstar 114GT 's 4-1/2" primary mirror. Because of the Newtonian design, the mirror of Celestron 114 mm GT Telescope gives fully color-corrected views that are best suited for astronomical use.

Every Celestron NexStar-GT Telescope includes a version of The Sky software Level 1 Planetarium software for exploring the Universe on your PC and printing out custom star charts of the sky. In addition, you receive the Nex Star Observer's List (NSOL) control software. Just connect your Celestron NexStarGT Telescope to your laptop or PC (with optional RS-232 cable) for click-and-slew ability to any object in the NexStar 's database.
