Get the whole family involved in astronomy with the NexStar 127SLT. It's computerized and motorized, so you can scan the stars with push-button ease. Aligning your telescope is simple and painless, as well: just center three bright objects in your eyepiece and press the align button, and your scope will do the rest. The telescope's onboard database has 4,000 night sky objects you can call up using the included hand control. You can get straight to the fun part of astronomy by letting the scope's fast and easy SkyAlign technology get your telescope dialed in. The included astronomy software lets you use your PC to print star charts for exploring a vast 10,000-object catalog.
Astronomers have a saying: "the best telescope is the one you use most." That's why Celestron made the 127SLT portable, so you can take it where light pollution doesn't interfere with your ability to see the beauty of the stars. The telescope's quick-release fork arm mount, optical tube and accessory tray allow for easy setup and transport — the assembly weighs less just 18 lbs. A handy auxiliary port lets you add accessories like Celestron's SkySync GPS module for even faster, more accurate auto alignment.

Overview: The NexStar 127SLT computerized telescope has a Maksutov-Cassegrain optical system, and comes with a built-in motor drive and a plug-in hand controller. It can be used for both terrestrial and celestial viewing. The 127SLT comes with a sturdy pre-assembled steel tripod and two eyepieces (25mm and 9mm).
Maksutov-Cassergrain: The Maksutov-Cassergrain optical system uses a combination of mirrors and lenses, and is referred to as a compound or catadioptric telescope. This system uses large-diameter optics while maintaining very short tube lengths, which makes the telescope very portable. The Maksutov-Cassergrain design consists of a corrector plate, a spherical primary mirror, and a secondary mirror, requiring light rays to travel the length of the optical tube a total of three times.
StarPointer Finderscope: The telescope comes with a StarPointer red-dot finderscope which helps you to aim the telescope at a distant target. The finderscope must first be aligned with the telescope before use. This is done in the daytime by pointing the telescope at an object at least a quarter mile away, centering the object in the eyepiece, and aligning the finderscope's red-dot LED to the distant object. The StarPointer is powered by a CR2032 Lithium (coin-type) battery (supplied).
Hand Control: The NexStar 127SLT comes with a plug-in 19-button hand controller. It attaches to the telescope's fork arm via a coiled cord. The hand control has a backlit LCD window with a dual-line, 16-character display screen, direction keys, and catalog keys to help you search through the nearly 4,000-object database. With an optional RS232 cable, you can interface with a computer and control the telescope remotely.
Sky Align: During setup, Celestron's Sky Align technology can quickly and simply align the telescope. By pointing the telescope at three bright objects in the sky, and entering date, time, and your location on the hand control, the telescope automatically and accurately aligns itself. In addition to Sky Align, other alignment procedures include Auto Two-Star Align, Two-Star Align, One-Star Align (for locating large bright objects only), and Solar System Align.
Motor Drive: The NexStar 127SLT is equipped with a fully automated GoTo mount with a database of nearly 4,000 celestial objects. This allows you automatically locate the object you desire via the built-in motor drive. Once you have the object in the eyepiece, the motor drive will also help track the object as it moves across the sky. When the drive is properly set, the object you are viewing should be centered in the eyepiece for long periods of time.
Eyepiece/Star Diagonal: The NexStar 127SLT features two eyepieces: a 25mm and a 9mm eyepiece. The 25mm eyepiece gives the telescope a magnification of 60x, while the 9mm eyepiece increases the magnification to 167x. The 127SLT also includes a Star Diagonal, which diverts the light at a right angle from the light path of the telescope. It allows you to observe in more comfortable positions than if you were to look straight through.
Power Requirements: The NexStar 127SLT can be powered by eight "AA" batteries (not included), which are stored in the telescope's base. In addition, you can operate the telescope using the optional PowerTank 12-volt power supply, via AC power using the optional AC adapter (#18778), or your vehicle's battery using the optional Car Battery Adapter (#18769).
Accessory Tray: The telescope comes with an accessory tray which provides a place to put extra eyepieces or other items while you're using the telescope.
Included Software: Included with the telescope is "TheSkyX -- First Light Edition" astronomy software on CD-ROM. The disc contains a 10,000 object database with printable sky maps and 75 enhanced images. Also included is NexStar Observer List (NSOL) software allows you to control the telescope with a computer via an optional RS-232 cable (#93920).
