I bought a Meade HD-60 25mm off CN and realize that an inner lens surface has some sort of dirt streaks. Visible brown smears that mildly impact views. I've checked the top surface as well as the very bottom surface and that is not where these marks are. They must be inside somewhere. At this point, I won't use the eyepiece much if at all unless I can clean it. The streaks are just too annoying.
I cannot figure out how to unscrew any portion of the eyepiece. I know how to take your average plossl apart but this is quite different construction. It has one of those movable/telescoping eyeguards but there seems to be no way to separate the bottom metal portion of the eyepiece from the rest of it.
Anyone have any experience taking one of these apart? Thanks for any help!
