Any ideas on how to get a replacement and re-attach it. The 'scope is a 2000 model, so out of warranty - and is otherwise in perfect condition! I live in a place where I cant get it to a dealer (Grand Cayman). PCH

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.

Hi, My Mead ETX-90EC Astro Telescope Has Never Been Able To Focus From Day 1 I Purchased The Telescope NEW I Replace The Batteries Twice, Still No Results I Can See The Moon But Its Very-Very Blurry Where Can I Find A Repair Service. I Live In New York Thank You, James S. [email protected]


There is a tiny setscrew on this side of the focus knob. Make sure it is tight or the knob will just spin around the shaft.

Red wire from battery off, where does it go? - Meade ETX-90EC (325 x 90mm) Telescope


It broke off of the circuit board. Actually I PURPOSELY cut both of the battery wires OFF! This makes it much easier to work on the internal gears.Just buy a separate 12 volt power pack and stop using the internal batteries. The scope functions better on a regulated separate power pack. Buy the proper 12 volt cigarette lighter style power cord.I never use the internal batteries and have removed them completely from the scope. If they leak they will ruin the circuits inside the base of the scope.

Secondary miror glue spots.What can I do? - Meade ETX-90EC (325 x 90mm) Telescope


Gently use pure acetone (no perfume or dye) on a q-tip. just dampen the q-tip and only use one stroke per q-tip do not use any pressure as this will damage the mirror surface Use distilled water to rinse mirror. LET AIR DRY!

I purchased a Meade ETX 90 EC 325X90 MM Telescope at Christmas for a friend of mine. When he went to set it up on the tripod, he said that the focus button was loose and it would not adjust to focus in. Neither one of us are familiar enough to repair or start taking apart the item. Someone suggested to take a crescent wrench and fit it in the hole, but we don't see what hole they are talking about. Of course I purchased the telescope on e-bay and there is no return or refund. Can you assist me or tell me if there is a local dealer that could look at it for me? I live at 2401 Madison Avenue,. Granite City, IL 62040? Thank you. Alicia


It is very simple.Their is one shaft appear near eyepice.please you go at electronics componant shop and buy a knob which is suitble to fix.You focus button ready to work.

Meade ETX-90EC the declination lock won't lock any more... is my only choice to send it back to the factory (booo...)?


Unfortunately, you will probably have to send the unit in for sevicing, to restore this function. This type of scope is a highly precision device, and parts can wear, causing a loss of certain functions. I wouldn't recommend trying to take the unit apart, unless you're a super mechanical person. Even if you did, you'd have to identify the worn or failing part, and that would be a challenge without the tools and replacement parts they have at their repair facilities. Some cities have "sky clubs" and some of the people are avid skywatchers, and might know something about this particular problem, and may be of help, but that might your best alterntive to having it serviced right away. Often times, a switch or part can get slightly compromised by dust, or lint, and require a minor cleaning. Here's Meade's Support Site, in case you don't have it: http://www.meade.com/support/auto.html Good luck, and hope this helps.

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.
