Maximum exposure time without correction

I would like to know the maximum exposure time without having to do error correction. Surely it depends on the mount quality and alignment. It's just to have an idea. Supose a good quality and well aligned mount.
Also supose prime focus on a 10" f/5 scope using a standard astronomy ccd device.
