All of my sensor cleaning gear arrived this morning and I have dived right into it. Using the glass polish I believe I have removed the obvious spots, they came off pretty easily. I have inspected and reinspected every square mm of the sensor using the magnifying lamp (3X), the Sensor Loupe (7X), and believe I have it servicable now. My only concern is that I may have 'gone too deep' with the polish and I need to do some test shots to check on the quality of the job. Photos attached. Note that the sensor surface is highly reflective and when moved shows shifting light diffraction off the surface that appears to form a border in the one photo, it's not actually there but a reflective artifact from the light.

Update: The camera is re-assembled, but I have left the cover glass off the sensor in case I have to go back in and do some more work. I am also leaving the cooling off for the moment while I do some test shooting at ambient. I need to be sure it's as good as I can get it before I button it all up into an argon chamber. So attached is a sunny daytime sky shot. I have expanded the RAW file 100% in Photoshop and it looks pretty clean. The dark spots in the lower left are a couple of specks of dust probably on the MC Clear Clip-in filter. I can see some stuff on the very edges of the sensor and in the corners which needs more attention (hard areas to work into) , but looking promising. I will put this camera on a scope tonight and try to get some long subs to see how it goes. Stay tuned.
