Before I get out the Ajax and brillo pad are there suggestions to the proper care and cleaning of the front lens on my SCT? I have dusted the barnacles with the "dust off" air can.. Looks like there is some dust on the "inside" of the corector plate..is that something Celestron has to do... thanks for any guidance .. John M in Astoria, OR.

I've had to get mine cleaned once. You don't have to send it to Celestron. I took mine to a local Astro store and watched them do it. It's fairly easy but you need to be careful. My cost was $40 and it's been fine ever since.
