Edge-HD Optical Design
The EdgeHD optical system combines all of the compact power popularized by the SCT with an improved high definition optical system for wide field, astrograph quality images. As a visual instrument, EdgeHD optics deliver pinpoint images even with your widest field eyepiece. You can search for all of the Messier Catalog objects, and see hundreds of other NGC, IC and Caldwell objects with amazing clarity. For astro imaging, EdgeHD optics produce aberration-free images across your favorite CCD or DSLR camera. All EdgeHD optics are designed to produce an extremely flat focal plane precise enough to match the strict tolerances of the largest commercial CCD detectors, allowing stars to be in tight focus to the very edge of the chip.
The CPC Deluxe HD Series' internal GPS receiver automatically downloads the date and time from orbiting satellites and pinpoints its exact location on Earth. This eliminates the need for you to manually enter the date, time, longitude and latitude.
Celestron's Revolutionary SkyAlign
Once the CPC's internal GPS has established the telescope's position, aligning the telescope is as easy as 1-2-3! Simply locate and use the hand control to manually point (slew) the telescope to three bright celestial objects. You do not need to know the names of the stars you may even pick the Moon or bright planets! Celestron's NexStar software technology will model the night sky to determine the position of every star, planet and celestial object above the horizon. Once aligned, the remote hand control allows direct access to each of the celestial catalogs in its user-friendly database.
Celestial Object Database
The CPC database contains over 40,000 celestial objects including Messier objects, the Caldwell Catalog, as well as NGC Galaxies, nebulae and planets. User-definable filter limits make navigating through this expansive database quicker and easier. Filter Limits let you filter out objects that are outside of your local horizon (ie, if trees or mountains were in the way). There's also "Solar Sys Align" that lets you align on the Sun or Moon for daytime observing -- it is easy to use this to see planets or bright stars in the day.
All EdgeHD optical tubes are equipped with a removable secondary mirror for fast f/2 CCD imaging. Not only does imaging in the FASTAR configuration allow for exposure times that are 25 times faster than at f/10, but also yields a field of view five times wider. A perfect combination for imaging your favorite wide field objects in a fraction of the time. (FASTAR imaging requires a third party lens assembly in place of the secondary mirror).
