At the risk of hijacking.......I had no success with automated guidestar acquisition until doing a library of bias/darks for the Starshoot autoguider. Even so, CCDAutopilot is very unreliable re-acquiring (in my hands), while CCDC seems rock solid. These issues may be important down the line, so agree a decent low noise (and low artefact) guidecam important. I was surprised at number of defects in a lodestar at a local site recently - certainly made dithering a challenge.
