Hi there. I started looking around your forum a week ago and decided to join so I can ask a question, if I may. I recently purchased a C11 secondhand. It had the mirror mod done, ( packing up the focus lever with silicone ) I checked it out under a suburban sky and the optics looked great. Today though I had a close look at it in the daylight and there appears to be smudges or regions where something has been deposited on the main mirror. I was thinking perhaps some residure from the curing of the silicone has wafted around onto the surface? Anyway I didn't want to strip it down and clean it unless necessary and I thought a few opinions from others here might help me make up my mind.
The marks are hard to see without some illumination, here are a couple of photos taken under a dim white led and one under a flash. Thanks in advance for any opinions.
