do you mean that you can find a best focus point (image gets worse as you move the focuser either side of the best point) but the best focus is poor - or do you run out of movement in the focuser before it gets to a sharp image?
if you can reach focus, but the image is no good, what exactly do you see? eg does it have colour fringes, elongation in one direction etc?
