This system allows for autoguiding a GP or GP-DX mount equipped with the Sky Sensor 2000 or a properly modified DD-1. It includes a CCD Video Camera, a LCD screen and the control box. I also have all the cables except the one that leads to the Sky Sensor. All that is needed is a "six pin" phone style cord. The camera can guide on stars to about 5th magnitude. I also have a copy of the English version of the manual. Brand new in the latest Vixen catalog, it lists for about $900 for the set up I have. I will sell this one for what I paid: $400 plus $10 shipping. Please email or call with any questions or for some pictures. Money order/Cashier's check preferred. Paypal requires 3% additional to cover the fee. Thanks.
