eyepiece clean/repair question

I have a Meade 6.7mm UWA that has a tiny but very noticeable black smudge near the center of the FOV. It doesn't seem to be on the surface of any of the accessible lenses. I therefore assume it is on one of the internal surfaces. VERY noticeable when viewing Jupiter, for instance.

Is there someplace or someone (Meade, for example) that I can send it to for dismantling and cleaning. Any idea of the cost involved? IS this something I should try myself?

thanks,

david

I've done this to all my eyepieces, more than once. You should know just by looking at it if you feel confidant in disassembly. I've used jeweler's screwdrivers and pocket knives to unscrew the retaining rings and was careful enough not to mar the finish. You have to be careful and remember or make notes of the order and way they face of each element. If you couldn't fix a faucet or a toaster or grind your own mirror, then nah, don't try this at home. But then I also repair old vacumm tube radios and stereos so I'm a bit of a tinkerer. Ron
