Item #  09759
Mfg Model #  11075-XLT

The CPC 100 XLT combines large-aperture Schmidt-Cassegain optics with an innovative GoTo fork mount for a price that is hard to resist. The 11" (279mm) f/10 optics boast Celestron?s proprietary StarBright XLT high-performance coatings to ensure bright images. The altazimuth mount offers computerized pointing to 40,000+ astronomical objects via the flash-upgradeable hand controller, so you will never run out of amazing things to observe.

The Celestron CPC 1100 XLT GoTo Schmidt Cassegrain Telescope?s internal Global Positioning System (GPS) system and revolutionary new SkyAlign technology make quick work of the initial alignment for computerized operation. The GPS automatically downloads date and time information from orbiting satellites and pinpoints the telescope?s location on Earth. This eliminates the need for you to manually enter the date, time, longitude, and latitude. And with SkyAlign, you just aim the telescope at any three bright stars or planets in the sky - you don?t even have to know their names! Then -- presto! - the telescope is oriented and ready to take you wherever you want to go.

User-definable filter limits make navigating through the expansive object database fast and easy. Filter Limits let you filter out objects that are outside of your local horizon (i.e., if trees or mountains are in the way). The Identify feature tells you what you?re looking at, but it can also be a very fun way to tour around the sky. Just point the telescope up somewhere and ask it to identify Messier objects (for instance) and it will show you the 5 nearest M objects to your position and let you go to them. You can keep doing this for different parts of the sky or for different object types.

The newly designed tripod has heavy-duty stainless steel legs and a spreader bar for excellent rigidity. Other features include periodic error correction (PEC), an autoguider port, and input for 12-volt power.

The StarBright XLT System - What Makes It Different Makes It Better
Celestron is proud to introduce a revolutionary coating system that outperforms any other coating in the commercial telescope market. All Celestron Schmidt-Cassegrain telescopes sold by Orion include this premium-quality optical coating.

There are three major components that make up Celestron?s StarBright XLT high transmission optical system design:

1. Unique enhanced multi-layer mirror coatings
The mirror coatings are made from precise layers of Aluminum (Al), SiO2 (quartz), TiO2 (Titanium Dioxide), and Si02. Reflectivity is fairly flat across the spectrum, optimizing it for both CCD imaging and visual use.

2. Multi-layer anti-reflective coatings
Made from precise layers of MgF2 (Magnesium Fluoride), and HfO2 (Hafnium Dioxide). A rare element costing nearly $2,000 per kilogram, Hafnium gives us a wider band pass than Titanium, which is used in competing coatings.

3. High Transmission Water White glass
Celestron Schmidt-Cassegrain optical systems with StarBright XLT coatings use Water White glass instead of Soda Lime glass for the corrector lens. Water White glass transmits about 90.5% without anti-reflective coatings. That is 3.5% better transmission than uncoated Soda Lime glass. When Water White glass is used in conjunction with StarBright XLT?s anti-reflective coatings, the average transmission reaches 97.4% - an 8% improvement!

These three components of StarBright XLT coatings result in one of the finest coatings available. The peak transmission for the systems is 89% at 520 nm. The overall system transmission is 83.5% averaged over the spectrum from 400 to 750 nm.

NexRemote Telescope Control Software
NexRemote allows the user to control a Celestron computerized telescope from a personal computer. Everything that is done using the telescope?s hand control can now be done remotely from a PC or laptop. NexRemote provides full emulation of every aspect of the Celestron Computerized Hand Control including:

  • Alignment in any tracking mode
  • Database of objects
  • User objects
  • Hibernation
  • Connect to popular planetarium programs

In addition to emulating the NexStar Hand Control, NexRemote adds powerful new features including:

  • NexRemote talks - Keep your eyes on the stars instead of the LCD by enabling speech support
  • Control the objects you want to see and the order that you see them
  • Create and save custom tours by launching NexTour
  • Use Night Vision Mode to reduce the effect of the laptop screen on your eyes
  • Wireless control of the telescope with Optional Gamepad Support
  • Connect to your personal GPS device to NexRemote with NexGPS
  • Download NexRemote updates online to use the latest features
