O.K. Guys, I recieved lots of technical questions. I pulled out the computer unit and manual from storage Today and I will tell you all I know. The manual is dated 1999. The title on the manual is "Skysensor", and the box is labled Celestron. The motors match the mount as though they were original equipment (black/Vixen)...The Pendant/ Comtol unit has a RS232 port on the top. In reading the manual, it explains it is a computer interface port, and the command set looks like they are waitng for an ASCII string from something like a basic program. The string looks like it will go to co-ordinates, or pre-position objects in the control Pendant's library. Essentially it looks like it expects the computer to replace the keyboard in a kind of emulation mode. The motors are pretty powerful, (I am told) and will require a decent 12 volt battery for the system ; like a motorcylle battery for example. Cables are included.
It looks like the Computer system was seldom used. (I only used the mount)I have the manual for the GoTo..The pendant is about 10" tall 5" wide ans 3" deep.It has a membrane keyboard with a liquid Crystal display. Beyond these questions, I have no answers about the computer.
This is an older Celestron/ Vixen Sky Sensor mounted to a very nice Super Polaris mount, not the recent Skysensor 2000 "PC", however the Mount is worth almost as much as I am asking. Included is a non-illuminated polar scope, Wooden legs, a 6# weight and both manual slow motion controls. The mount is in like new condition, legs have usual/ minor nicks. Price is $600 plus packing/ shiping/ Insurance in CONUS. The Super Polaris is considered a better mount than the Great Polaris and is rated for a Normal #15 payload. I have the manual for the GoTo..
