The secfondary precision mirror is missing was this attached to the telescope or is it a separate attachment and can this be replaced?


This is REQUIRED for a reflector telescope. To be honest if it is missing the cost of replacement will exceed what you want to spend on that scope.

If you bought it new, return it as defective.

We have a eduscience telescope (bought several years ago) Our grandson found it our attic and states that it is missing a diagonal mirror. Where can I find one.


Measure the hole in the focuser-- diagonals come in 3 sizes:

.965, 1.25, and 2 inch sizes.

Your scope is probably a .965 contact Surplus Shed and see if they have one:

I think i am missing parts. what connects the diagonal mirror to the focuser drawtube?


The diagonal simply slips inside the hole at the rear of the telescope. A small thumb screw secures it. The eyepiece then goes into the diagonal.

We've a 600X power edu-science telescope which seems to be missing the inner ring which might be what the instructions call a secondary precision mirror.


The secondary mirror is a small tilted mirror near the front end of the telescope mounted on what's called a "spider". It reflects the light from the large mirror in the bottom back out through the hole in the focuser.

Usually these are already assembled and in place when you buy a reflector style telescope.

Piece of felt covering mirror, is this suppose to be there?


Here is the manual for your telescope--

http://meade.com/manuals/TelescopeManuals/Reflectors/Meade%20114%20EQ-ASB%20manual.pdf

The mirror at the bottom should NOT be covered-- with felt? Unless this was something Meade did to protect the mirror from dust and dirt during shipping?

Eyepieces not fitting into 90-degree penta mirror


Here's the link to the user manual if you need it; http://www.bushnell.com/customer_service/manuals/telescopes/78-9440_Voyager.pdf Check the bottom of page 3, I think it answers your question - eyepieces should insert directly into the penta mirror. check page 9 for a diagram showing the whole assembly. If it turns out you have the wrong eyepieces, you can contact bushnell's spares department on; http://www.bushnell.com/customer_service/partsinfo.cfm?section=General%20Use Hope this helps, please ask again if you need more info :)
