I have never cheked a magintude value of the brightest star for the DSOs I took picture of but here it says:

Many webcams have a limited exposure time that sets the lower limit on how dim a guide star can be
used. With an unmodified Toucam, I can easily guide on a magnitude 7 star using an 80mm refractor as

a guide scope or on a magnitude 9 star with a 203mm Schmidt-Cassegrain guide scope.
