Scott, I've had quite a few of these apart, both Meade and Celestron.
You don't need to fear removing the corrector and cleaning the
secondary. The IMPORTANT thing is to be sure the corrector is
replaced in EXACTLY the same rotational position. If it isn't already
marked, marked it with white-out or finger-nail polish. Mark it in
such as say at to facilitate replacing the corrector accurately. Not
a big deal. It'll probably still be in fairly good collimation too.
Keep the OTA horizontal to the ground when removing the retaining
screws and corrector. This way, nothing will fall onto the mirror, if
by chance that would happen.
You can use a Q Tip and denatured alcohol to remove the speck, if a
simple swipe from the edge of a tissue won't remove it.
Most imporantly, this is an easy-to-accomplish task and something we
can do readily without paying out any money to anyone.
Have fun! Dennis
