Old SkySenor needs updated cables

Post by Lancelot38 » Sun Sep 26, 2010 10:15 pm

I have an old SkySensor (ca. 1986 - Number 501773) that is still in mint condition. After nearly 25 years, I am a determined to learn how to use this with my Celestron Super Polaris C-8 for astrophotography. The unit has a 25-pin RS-232C port on the back and it has an autoguide feature. Without autoguiding, I get decent tracking but the pulse motor results in consitent drift equal to the time between pulses. Can anyone tell me how I would go about adapting this port to work with USB or serial for autoguiding?

Does this mount have a separate autoguide port? If so, do you have any technical information on the pinout for it?

The original instruction manual indicates that it is adaptable to an auto-guider. I have never seen the auto-guider designed for use with this unit but I would assume it would plug into the RS-232C port which I have photographed as attached. The pinout looks fairly simple but there is no schematic. I'm sure I could figure it out with a little effort.
