Seriously... the autodark is pretty important. You only need to have a single hot pixel develop...and they do...and your autoguider will happily guide on it, rather than a star, ad-infinitum. (guiders are dumb..they just look for the brightest thing in the field, and guide on that, even if it is a hot pixel )

Autodarks remove the problem.
