Well, the last buyer flip-flopped, so here we go again.
SBIG Relay Adapter Box with cables is in MINT condition since it's never been used or even taken out of the plastic wrap that it arrived in from the dealer.
A must-have item if you wish to use your SBIG CCD camera with a Losmandy mount or other mount that does not use a digital interface, it isolates the camera from the mount and safely triggers the corrections. Without it, you can burn out the mount's electronics!
The relay box can be used with any drive system that does not support SBIG Models ST-5C, ST-237, ST-7, ST-8, ST-9, ST-10, ST-2000 digital interface. The unit provides four SPDT relays (like the Model ST-4 interface) and offers complete isolation of the camera from the hand controller electronics.
New price is $109 plus about $7 shipping.
Asking $70, including shipping by insured Priority Mail to anywhere in Conus.
