Hi Pete
I use PHD, but I've only ever used it on full auto for all the settings.
I literally plug it in, click on the camera, click on the mount, and hit go.
I only have problems losing the guidestar if it's too faint. I usually try and keep the exposure as short as possible (0.05, 0.1 or 0.2 secs), because i'm not usually polar aligned well enough to trust any longer than that
