Your worst issue with it would most likely be that you know it’s not perfect and even though you can’t see the effects of the scratch, you know it’s there. Try not to let it drive you crazy. When I modded my Mak Cass I had to open it up and instead of taking the entire back with mirror off, I started to work on it with just the meniscus off in the front. I ended up dropping a nut down the tube and it touched the primary. I shined my flashlight down at the primary and thought I could see a tiny mark which I promptly tried to wipe with a lens pen so I wouldn’t have to clean the mirror and back assembly.
That just made another weird looking mark. I then took out the back assembly with mirror and wrapped the assembly up so it was water sealed and gently cleaned the mirror. A slightly different hue where I had touched the lens pen to it in a very small spot. No other marks on the mirror which was now pristine again after a distilled water rinse and mopping the last little drops by just touching the drop and not the mirror with a corner of a paper towel. Perfectly cleaned, but I knew it was not like the brand new mirror from factory.
Tested it and everything looked beautiful. Have had perfect seeing nights where the scope performed on planets at 400x and it’s a 6” scope.
Ended up buying a used one to compare to mine. Used one had pristine mirror. Never opened up, etc.
Performs exactly like my first one. Can tell zero difference. Stopped worrying about the first one.
