Amen to that. I did a bit of digging it was Johannes Schedler and Ken Crawford that set the record in 2007, Mag 24.8 with about 16 hours of combined data.
As a ballpark figure, a CCD should be able to reveal stars about 50x fainter than visual observation through the same scope.
Of course the highest QE CCD on the planet will not solve the problem of eight 8th's of cloud over Sydney right now
