Two lenses. The ETX 60 is a achromatic reflector

I had this problem after a repair and was told to unconnect all boards and then reconnect them. Amazingly it worked and is worth a try. If this does not cure your "runaway dec" , call Tony Castanza at the Astronomy Shoppe in NH. He fixed my LX200 and may have some suggestions. If your Dec motor resistors need tuning I'm guessing he can do it.

Need more information- several Meade scopes have a flip mirror like the ETX 90 for example. Usually it is in the position to use with an eyepiece. However it can be flipped so the rear port can be used on the telescope. Hope that helps. There is a known issue with these old flip mirrors- the adhesive holding the mirror can fail. You must disassemble the scope and apply new adhesive to hold the mirror in place.

I recommend you check with Meade support. You can contact them online at http://www.meade.com/support/contact/

Just as it says - contact Meade tech support. You can contact then online at http://www.meade.com/support/contact/

You may try a camera store to see if they may know where someone might look or send an email to the Contact us link on their site.

Letting any electronic device set is the hardest thing you can do to it. However, most electronic devices will regain their functions if you leave them powered up long enough. It make take a while but it will probaby eventually start working again. Be sure and check any battery terminals for acid build up and clean them good. Hopefully it will come alive again Col.

I'm assuming you will change these ICs yourself and that's why you're asking. If you have access to the circuit board, then you should be able to find some numbers on the IC which you think is blown. If you can pull that IC and look at it's underside you may be able to find a number you can search on the internet for. Or you can find a number on the circuit board itself and maybe find the company that made that board and contact them to find out the IC you need. You can probably find an IC match as long as the pins are in the same order and the voltages are the same. Good luck!

Try going in on google or what ever you use and type your model and part number you will find dealers for device and parts...Also if you know hiw go into EBAY and just type your model in the search window ..it will give you everything on EBAY protaining to your model.. Good luck..

If there is nothing on the objective lenses or eyepiece lenses then it most likely needs collimation. This is where you adjust the secondary mirror while viewing an out of focus star. You need stable sky conditions to do this.

There are most likely three small screws at the front of the telescope and these are what you use to adjust it. As one screw is loosened then another is tightened. Do this in very small increments. If you have your manual it should outline how to perform this. If not go to this web site: http://www.astrosurf.com/legault/collim.html. It will show examples of how objects look both in and out of collimation. There is a section further down the page for SCTs.

A very handy tool for this is to replace your screws with Bob's Knobs (http://www.bobsknobs.com/) . These replace the screws and allow you to adjust it by hand instead of a screwdriver.

The other focusing problem I've experience with my Celestron SCT is to have the focus knob loosen up and then slip as I turned it so that I could never focus with it.

Good luck and clear skies!
