Yeah, I believe the longer the sub the better. From what Alex was saying to me on another thread, 5 min subs with a dedicated CCD camera aren't going to be much better noise wise than DSLR. It's when you get 20min+ subs that cooled CCD cameras will really start to kick some booty.

Dave, the reality is though from what I have been told is that subs are usually no longer than 10 minutes. Anything longer than that can be wasted if there is a guiding error or satellite trail. It is an interesting business for sure.

Paul, I really like this image. None of the minor issues can detract from the fact that this is a fantastic image!
