The Celestron CPC Deluxe 1100 HD 11" Telescope Optical Tube Assembly features the proprietary EdgeHD optical system, which corrects for both coma and field curvature, providing aberration-free images to pinpoint stars across the largest imaging sensors and all the way to the edge of the widest eyepieces. Celestron's StarBright XLT coatings on all optical surfaces deliver brighter images and increased light transmission. The beefy dual-fork arm mount anchors the telescope for ultra-precise tracking, but weighs just 70.5 pounds and includes rugged carrying handles to make setup quick and easy. As soon as you turn on your CPC Deluxe HD, you'll be guided through Celestron's simple SkyAlign procedure. The telescope walks you through centering any three bright objects in the eyepiece. From there, it's ready to locate and track more than 40,000 celestial objects.
