The #506 Meade AstroFinder celestial CD-ROM software displays over 10,000 astronomical objects(galaxies, nebulae, star clusters, stars, and planets) on your Windows-based PC, and enables even beginners to easily locate and identify objects to observe with the telescope or to print out star charts for use in observing sessions.
After establishing an alignment, you merely point and click a specific point on the sky map showing upon your computer's monitor and the telescope slews and stops with the chosen area within your eyepiece.
The included Cable Connector Kit permits connection of the ETX-60AT, ETX-70AT and ETX-80AT's #494 Autostar controller and a PC, for downloading of new software to the #494 Autostar or for updating of Earth satellite and other celestial object positions.
The cable included connects erial ports to the RS-232 jack(identical to a North American telephone line). PCs which have no RS-232 connection, such as those with only USB ports, require a standard USB/RS-232 computer accessory(made by Meade and many, many others).
