The second problem was to come up with an autoguider camera. Mel Bartels updated his fine scope.exe program that I use to operate the scope to accept inputs from an Accutrack Photodiode Autoguider. This input actually works quite well, but it only guides in one axis. This is enough if most of the motion is only in one axis, but dual axis guiding is what is required. They are not cooled, and so their exposure time is limited, which limits their capability for imaging deep space targets, but an autoguider does not need long exposures.
Quick images are what is needed.
Achay Doan and the team of Marty Niemi and Bob May have each developed software that provides autoguider outputs based on a Black and White QuickCam as the sensor. I have modified the circuit slightly to interface to Mel Bartel's motor control circuitry. A .gif file of the circuit schematic is available by clicking HERE . There is a small list of sites specializing in QuickCams at the end of this article. The following shot shows two t-mount adaptors.
