Need More Focal Length

To focus closer your focal length must be longer. Planets are enough closer than stars that you need to adjust. For a quick test, try unseating the eyepiece to extend it out a bit and try again. Also it's just difficult to obtain really clear views of the planets from the earth's surface. I'm no expert by any means, but came across the same problem on my old Edmund 4.25 reflector. In my case, the permanent fix was to adjust the primary mirror to be farther away. Despite this adjustment, I never got better results than only a fuzzy ring myself.
