Hi,

I own a 6 years old Meade LX10. Recently Meade Europe has repared the
declination slow motion knob. Meade also has cleaned the optics and the
inside of the correction plate and the internal mirror. All, including
the transport of the telescope. for free. So it didn't cost anything.
Also a very good service!

But when i looked inside the telescope I noticed:

- about 3 very small dark spots (metal pickles??) on the internal
mirror;
- about 4 very small dark spots (pickles) on the inside of the
correction plate;
- further on I saw just about 8 very small pickles on the inside side
of the baffled tube.

When the telescope just returend form Meade, I didn't see these bugs.
So they must have entered later. But I only used the telescope once
after it returned from Meade. Also it has been transported once.

Further on the optics and mirror seem to be very clean and clear.

When I read the manual of the Meade LX10, they say I don't have to
worry about these small "bugs" on the inside of the optics, because it
will not affect the quality of the optics.

Can anyone say to me if that is true?? Are it the remains of the
cleaning by Meade?? And/or how did these "bugs" enter the telescope?
When I don't use the telescope it is standing in the living-room, fully
equiped. I mean with the diagonal and eyepiece installed. Is that O.K.?

Little tiny spots are not noticeable visually, and may be little bits of dirt or dust left over from the cleaning, or bits of debris you accidentally let in. Either way, they will affect nothing.
If they REALLY bother you, you can remove the secondary/corrector plate ensemble and blow them off with an ear syringe, but you'd have to recollimate your scope after doing so.
