Greetings - I've got a STX11002, and I last baked out the desiccant plug about 8 months ago. Apparently over the summer, sufficient moisture got into the CCD chamber to make a mess on the chip. You can see the residue left on the chip. So the question is, is there any way for me to clean this myself, or does it need to be shipped back for maintenance? This is on the interior of the chamber, presumably on the chip itself (if the chip is protected by an interior window, then the residue appears to be on that window). It is NOT on either the inside surface of the external chamber window. Thanks for any help you can provide!
