Has anyone ever dared take apart an A-P lens cell? It's a 155EDFS Starfire air spaced triplet made in 1998. I don't mean just remove it from the stationary part attached to the tube, but do that, and then actually separate the three lens elements and clean all six surfaces?
I realize it's not recommended, and I expect a lot of folks to tell me not to do it, but there are smudges that appear to be internal - and original - that I'd like to finally get rid of.
How dicey is it to put them back together and get everything realigned properly? Are the edges already marked for orientation and alignment?
Let me add that I'm super cautious, not mention nervous, about cleaning lenses. In fact, I haven't even cleaned the surface of this objective since I've had the scope. Thanks.

Send it back to AP, something seems fishy. First, 155 edfs from 1998 is an oil spaced objective, not air spaced. Second, looks like a couple of large bubbles along with the smudges, as if the elements had already been taken apart and messed up. Third, I've seen a LOT of AP scopes and I've never seen one come from them with an objective that wasn't pristine. Send it back, pay the price, and enjoy a nice scope.
