Celestron CPC Deluxe 1100 HD Computerized Telescope

11" EdgeHD Optics: A 0.42 Arc-Second Flat-Field System

At the heart of the CPC Deluxe 1100 HD is an aplanatic Schmidt-Cassegrain optical tube that corrects for both coma and field curvature. It gives aberration-free images and pinpoint stars across the largest imaging sensors and to the edge of the widest eyepieces, with a flat 42mm field. With StarBright XLT coatings on all optical surfaces, light transmission is maximized for brighter, higher-contrast views.

• Aberration-Free Field: The focal plane is more than three times flatter than a standard Schmidt-Cassegrain.
• Resolving Power: The 11" aperture achieves a theoretical resolution of 0.42 arc-seconds (Dawes limit), and every EdgeHD should resolve double stars to the Dawes limit.
• Obstruction: The secondary mirror obstruction is 12% by area and 34% by diameter.

Imaging-Focused Mechanics: Mirror Clutches and Thermal Vents

The CPC Deluxe 1100 HD incorporates mechanical features designed to maintain optical stability during long imaging sessions. Mirror clutch knobs on the rear cell hold the primary mirror in place after focusing and reduce image shift during long exposures.

Cooling vents on the rear cell let warm air out from behind the primary mirror, and each has an integrated 50-mesh filter that keeps dust out.

CPC Dual Fork Arm Mount: GoTo with Internal GPS

The beefy dual fork arm mount anchors the telescope for ultra-precise tracking and has rugged carrying handles. The optical tube and mount weigh 65 lbs and sit on a tripod with 2" stainless steel legs. An internal 16-channel GPS receiver supplies your location and time.

A reengineered drive train with a 6-inch brass gear, stainless steel worm gear and steel and nylon ball bearings lets the CPC Deluxe track accurately for up to 30 seconds without a wedge. With nine slew speeds up to 5° per second, the mount can move rapidly between targets or track with precision at sidereal, solar, or lunar rates.

NexStar+ Controller: 40,000+ Objects with SkyAlign

With the backlit NexStar+ hand control, you gain access to a comprehensive database of over 40,000 celestial objects. After a simple SkyAlign procedure, you can command the CPC Deluxe 1100 HD to slew to any object in its catalog, The internal GPS provides all necessary time and location data automatically.

To align, simply turn on the telescope and use the hand control to center any three bright objects in the eyepiece. The system builds a precise model of the sky and is ready to track. The database includes enhanced information on over 200 objects. With optional StarSense AutoAlign, the CPC aligns itself in under 3 minutes.

Visual Astronomy: 122x Magnification Out of the Box

The package includes a 2" star diagonal with 1.25" adapter and a 23mm eyepiece giving 122x. The 9x50 finderscope makes locating your initial alignment stars simple. With a lowest useful magnification of 40x and a highest of 660x, the telescope covers a wide range of powers.

The CPC 1100 HD as an f/10 and f/2 Imaging Platform

Most altazimuth telescopes are designed primarily for visual use, but not the CPC Deluxe HD. The tube is Fastar compatible: remove the secondary mirror and attach a third-party lens assembly to image at ultra-fast f/2.

For long-exposure deep-sky imaging at its native 2800mm focal length, add the optional HD Pro Wedge. With a wedge you can use All-Star Polar Alignment and Permanently Programmable Periodic Error Correction, and the CPC tracks smoothly through the meridian without a meridian flip.
