I've gotten down to 4th magnitude without difficulty in an average southern
california sky using my 11'' f/16 and about 150x. This was several hours
before sunset, using no filters. With the wilson 100" (JPL optical comm
experiment) a1064nm infrared filter and CCd camera, we got down to below 6th
at four in the afternoon. As I mentioned in an earlier thread, it was weird
to be observing stars in a dark field with sunlight pouring through the dome
slit! (I know these aren't really small scopes, but thought it might be
interesting)

How bright does a star have to be to be visible with a small telescope in
broad daylight?
