Telescope doesn't seem to work

I have a Meade ETX-90EC. Looking through it I see nothing. There is a silver colered nob that I believe is supposed to flip a mirror or prism in position but it does nothing. Any advice will be most appreciated.

Re: Telescope doesn't seem to work

This issue will be extremely hard to diagnose over the net but I'll give it a try. This is from Meade. The link to the online manual is below: Unable to see an image through the eyepiece:

  • Confirm that the lens cover has been removed from the telescope.
  • Confirm that the flip-mirror control (16, Fig. 1) is in the "up" position if using the eyepiece holder (4, Fig. 1) so that light is directed to the eyepiece (1, Fig. 1). Confirm that the flip-mirror control is in the "down" position if using the #932 Erecting Prism or doing photography with the ETX-90EC (see Telescope Controls and PHOTOGRAPHY WITH THE ETX-90EC).
It sounds like you are correct about a mechanical issue with the knob that moves the mirror. If you need a quick fix try your local camera repair or watch repair shop as the are familiar with intricate parts. The camera shop would be preferable as they know optics. Otherwise you could ship it to me and I could repair it fro you depending on the availibility of parts if parts were needed. Check my picture for my site address and get contact info there for more information.

I have a Meade ETX-90/ec telescope, the verticle lock knob will not thighten. It appears to be stripped. how can I fix it? Where can I get a parts list? Thank you

The bolt is stripped away from the plastic knob-- TAKE THE vertical lock knob off and inspect the bolt head-- you can use a STRONG glue to fix it -- epoxy or something similar.

ETX 60 altitude doesn´t work, but motor works

You need to tighten the friction lock - it acts as a slip clutch.

Optical mirror detached - Meade ETX-90EC Telescope

Your best bet is to ship it back to Meade for repair. they may not look it but there are very close tolerances that have to be achieved and takes certain tools for alignment.
