I haven't seen this answered yet, maybe I can get you
in the ballpark. I could not find the reference, but I
did read a few years ago (big help huh?) that a CCD
camera is the equivalent of ASA 20,000. If you take
into account an increase in overall QE over that time
span, a good guess would be 30,000-40,000. Obviously,
this is not ST-10 specific and is basically a wild
guess on my part.
