This eliminates the need for you to manually enter the date, time, longitude and latitude.Celestron's Revolutionary SkyAlignOnce 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 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 DatabaseThe 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). 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 Messier objects to your position and let you GOTO them. You can keep doing this for different parts of the sky or for different object types -- it is a lot of fun.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.Innovative FeaturesThe new CPC Series telescopes, like our acclaimed Advanced Series and premium CGE Series telescopes feature meticulously matched and hand-figured optical systems that are manufactured in our facilities in Torrance, California.
