Celestron NexStar RS-232 Cable
|Allows your computerized telescopes to be controlled using a laptop computer or PC. |
This cable is used to update the firmware in the Celestron NexSa=tar hand controllers or to allow wired remote control of the telescope using popular astronomy software programs. Note that the computer side of this cable is a DB9 serial port connector, and it is rare to find a computer having such a connection. In most cases you will also need a USB to RS232 adapter cable.
