Bintangchris: error 16 indicates a bad Hand controller, you may need to buy another one, also check all your connections going to the head assembly.Also error 16/17 indicates the HC cant communicate with the the RA/DEC control boards. It may need to go back to Celestron for repair.

Sky Prodigy does not have you align on stars but self aligns on images from the mount's camera (much like satellites do to orient), so ignore any incorrect suggestions about picking alignment stars, centering them, moving axes, entering correct dates or info. You should just turn it on and it figures everything out in 10 or so minutes alone.

Thiscode is likely a hand controller failure and you need to call Celestron. Mine did this too. good luck, you will need it...

Celestron NexStar 8SE shows No Response 16 and No Response 17 errors repeatedly.


Reset the hand controller and reload the firmware. You will need a special cable available from Celestron to load the firmware. The software is available for free on the Celestron web site.

For some reason the screen keeps saying no response 16 and the motors don't work. can you tell me how to fix it


If nothing is broken--

1. Make sure your batteries are NEW and or you use a separate 12 volt power pack.

2. The hand controller does a motor test when it powers up.

My Advanced Series GT mount does not power-up. I've replaced the AC adapter with no effect.


Sometimes the pin in the mount needs to be spread out to make good contact.

Also several other things can cause this-- broken hand controller? Does the power light come on? The one on the power panel?

If it does you either have a bad hand controller or a bad hand controller cable.

If the light does not come on try a 12 volt battery pack-- still no light? Then return to Celestron for repair. Contact them here:

8" Meade LX200 GPS: When I turn on the telescope the Autostar's red light come on but nothing else. After a few seconds I can use the direction motors with the hand controller only.


The first thing I would do is get another new hand controller cable. These can be ordered from Meade, or from a local dealer, or from www.scopestuff.com.

If a new cable does not help-- I would locate another Hand controller just to test if the controller has gone bad.

You can also try reinstalling the firmware into the hand controller, using the Meade version 5.9 updater software. You will need the proper computer cable between the computer and the hand controller to update the firmware.

Have you followed the instructions in the manual? The first thing to do is setup with the time, date and location, then select a 3 or 2 star alignment method to calibrate. Use ONLY the hand controller to move the scope to the stars.

Power goes out ETX 125


The hand controller cable may be bad. Get a new cable. If this does not work the hand controller may have bad firmware. Attempt to update the hand controller to the latest version of the firmware 43Eg.

Hand controller buttons not responsive


Eventually the pads wear out. There are repair kits you can buy to repair the contacts. Here:

or you can buy another new keypad from Meade.

Someone told me that the Meade Lightbridge could be equipped with Go-To Tecnology.T/F?


PUSH TO -- encoders can be mounted on to the base RA and DEC. After aligning on two known stars the hand controller will "point" to objects in the sky.
