That first link is a good one!
I've pulled apart an old Meade before (have meant to post the pics for reference, I'll get to it one day!) and it's not so hard to do.
IMPORTANT THING TO REMEMBER!
The corrector plate must go back on the same way it came off. The tape marking as demonstrated in the first link is the way to go. And dont break it! you can't get a replacement for it. The corrector plates are individually matched to each primary mirror so if you break one you've wrecked the scope.
The corrector plate can be cleaned just like a mirror once it's out.
Let us know how you go and send some pics!
