Also Peter, reduction of sub time to 5 minutes wont really help you either. Its thermal noise that your seeing. My observation was when the ambient temp was >10 deg C noise would start coming to a tolerable level, around zero and it was not bad at all. above 20 pull the camera off and enjoy the night sky with eye pieces!
