Ah ok, yeah it would depend on the size of the telescope and the brightness and distance of the star, I would guess that only a small portion of our galaxy has been surveyed.
The GSC-II has almost a billion stars out to magnitude 21, but there's hundreds of billions of stars in the galaxy, probably most of them would require this kind of effort (i.e. imaging a chunk of sky for days) to detect.
