Can't focus my telescope
If there is nothing on the objective lenses or eyepiece lenses then it most likely needs collimation. This is where you adjust the secondary mirror while viewing an out of focus star. You need stable sky conditions to do this.
There are most likely three small screws at the front of the telescope and these are what you use to adjust it. As one screw is loosened then another is tightened. Do this in very small increments. If you have your manual it should outline how to perform this. If not go to this web site: http://www.astrosurf.com/legault/collim.html. It will show examples of how objects look both in and out of collimation. There is a section further down the page for SCTs.
A very handy tool for this is to replace your screws with Bob's Knobs (http://www.bobsknobs.com/) . These replace the screws and allow you to adjust it by hand instead of a screwdriver.
The other focusing problem I've experience with my Celestron SCT is to have the focus knob loosen up and then slip as I turned it so that I could never focus with it.
Good luck and clear skies!

This is an old problem but I will answer it--
The rattling sound is a KNOWN ISSUE with these scopes. It actually does not affect anything. The scope is what is called an acromatic refractor. ALL ACROMATIC REFRACTORS show color fringing around bright objects. You would need to buy an APOCROMATIC refractor with 3 lenses to get true color correction. These scopes are very expensive to buy.
You can also use a "minus violet" filter to eliminate most of the color fringing in that scope. If the scope cannot be collimated it should be returned to Meade.

Cleaning my telescope
Safest way is to use a camera puff blower brush. A little dust will not affect the image. Do NOT touch the mirrors with a cloth as the dust will scratch the coatings. For really stubborn stains, you can rinse with distilled water and let air dry.
