• used for Celestron 8 SE
  This interface cable was essential for updating the software on the hand control and scope motor. Required the purchase of an after market cable to connect the RS-232 cable to hand control base outlet(no need to connect to the outlet on the scope base with the SE).

• RS 232 Cable
  Exactly as stated. Most all laptops will need a USB/RS-232 adapter, and driver in order to use this.
  Will probably require some computer knowledge.
  I cannot understand why the telescope manufacturing companies seem to stay about 10 years behind the current technology?

• Works perfectly
  My laptop doesn't have an RS-232 port (as usual) so I had buy a USB to RS232 converter (on ebay). After installing the proper ASCOM driver, my Celestron NexStar 114 can nicely be controlled from SkyMap. Just click on a star on the chart and the telescope slews there. Position/time synchronization is also really easy.
  NOTE: Before you buy this item, do find out what an RS-232 port is, and if your computer doesn't have one, buy an adapter first.

• need a Serial to USB adapter
  Yeah, these cables were created some years back and they need a mated serial to USB adapter added. I've used this config to plug it into a USB port and control my Celestron Nexstar using DeepSky and this cable. Also need to download the ASCOM files and free ASCOM Celestron driver.
