Thank you for your submission.
 
dannyleo - I have seen C90s with baffle issues repaired, some are chronicled in CN forums. The disconnected secondary baffle in your images (that's what it appears to be) can be re-attached. You need to get advice on the type of glue. Be sure to avoid Cyanoacrylate (aka: "crazy glue")  as they will give off vapors while curing which damage optics and mirrors.

I agree with ANM that the most likely cause of the damage to the primary baffle would be solar induced, though I've not personally seen that before.

 

I cannot imagine getting help from Celestron on this, but it's always worth a call to get advice.

 

These are not too difficult to disassemble, clean and put together, so don't be discouraged. 

 

The new Registry with these additions is offered in JPG and PDF.
