Do you have a fresh set of batteries in the scope? Better to use an outside 12 volt power pack with the Celestron 12 volt "cigarette" lighter cable.

This can be three things:

Low power

Bad cable from hand controller to scope.

Or a broken hand controller

Try fresh batteries first.

The power cable is the problem. The connector is loose fitting, and the cable is long and high resistance. Combined, these two things result in a significant voltage drop when slewing both motors. Replace the power cable with bigger wire, and tape the power plug down in the socket so it can't move. The other suggestion may help as well.

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.

I bought a used nexstar 130 Gt. The hand controller lights up and will move the scope, but will not display any information . Can this be fixed or do I have to get a new one? Thanks Lenny


First do a RESET on the hand controller --- also the b. Some of these scopes have a brightest adjustment.===rightness and contrast may be set too high.

The problem will be navigating the menu tree without seeing anything-- the menu tree is shown in the manual try to get to the reset by "touch". or to the contrast by touch.

Contact Celestron here is you continue to have issues with this:

Hi i just bought a acelestron nexstar 4 se telescope and when turning on the hand control it indicates transmit data and is stuck there , i can't set anything .


The hand controller is stuck in DOWNLOAD mode. Usually cycling the power off and then back on fixes this issue. Is the scope new? If it is take it back to the store and get a replacement (at least get a new hand controller).

The batteries are FRESH I would assume?

Here is Celestron's instructions for fixing these type of problems:

When I power on my Celestron CGE 1400 and i hit one of the directional buttons on the remote my telescope goes only in one direction like if one of the buttons is pressed all the time. Thank you.


You either have a bad hand controller or a bad hand controller cable. Try a new cable first. Also do a RESET on the hand controller and return it to the factory default.

If these do not fix the problem it must be returned to Celestron for repair.

Entered three stars to for alignment. Display shows 1. Mintaka,


Just by selecting a new star. It will ask you if you want to replace a previous alignment star. You need to re-read the manual for the Celestron hand-controller.

I have the Nexstar 8. It will not auto align or manual....


First do a RESET on the hand controller and make sure TIME, DATE, and SITE, are correct.

If this does not work then RE-load the firmware in the hand controller. If that fails contact Celestron customer service.
