How did your CPC replacement turn out? Those pictures of the corrector plate are from the first or replacement? Mine arrived with dusty OTA and corrector in/out. Celestron agreed to replace it but not drop ship like you got. Mine would have to go back first before they would send a new one out. My dealer has one in stock again and they along with Celestron agreed to allow me to take the one from dealer stock and replace it with the one Celestron was going to send me. Mine looked like a repack so I made some noise. With all the problems people are posting I'm considering cutting my loses and keep what I have. I know dust wont do anything and it seems to work well. Only issue I have is with grit feeling when fine focusing.
