Hello, I took my Nikon D50 to a local camera shop to get professionally cleaned several months ago and it came back to me with several splotches of dust on the inside of the viewfinder. The guy a the camera shop told me he couldn't get it out, but the dust was not there before. I'm not taking my camera back to that camera shop as it was not a good experience and I really don't want to have to pay the money to send it off someplace else. Does anyone have any suggestions on a way that I could possibly safely clean the inside of the eyepiece myself? I know for a fact it's on the inside of the eyepiece vs on the mirror/lens/sensor because none of my images show dust particles.
