Running on internal batterys? They may be depleated. A large diagonal should go into the focuser, if the reducer/adapter is removed.

Celestron 8se slews uncontrollably. Also gives a no response 16 on the hand control.


This is a well documented problem with that scope

New out of the box, our Celestron Nexstar 4se does not ask for our location. Cannot find it anywhere in the controls to input, therefore it will not align.


RESET the hand controller-- then turn it off-- wait 15 seconds and turn it back on. If this does not fix it the firmware will need to be reloaded. You will need a special cable from Celestron to update the firmware.

I would simply return the scope and get another one-- if the scope is new.

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 have connected the hand held remote control to me Celestron NexStar 80GTL and nothing happens. The remote will not power up. Don't know if the problem lies with the remote or is a more major...


Are the batteries fresh? You can also try a new hand controller cable maybe the one you have is broken which is a common problem.

Beyond that you can try to borrow another hand controller and try it. If none of these work, then you have a blown circuit inside the telescope. It will need to be returned to Celestron for repairs.

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:

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.

Celestron Nexstar 114gt telescope,hand controller lights up only


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.

Im trying to set up the location zone for Australia and can only get america and cant get any internatial cities. im in Adelaide, South Australia


You can enter the Latitude and Longitude of your SITE rather than the city. Also check on the Celestron.com web site for updated hand controller firmware which you can download and install. You will need a special cable (which you can buy) that connects the computer to the bottom of the hand controller.

The azimuth adjustment keys don't work


Send it back along with the hand controller describing the problem. Could be several things including a bad hand controller. If there is a local astronomy shop nearby take the scope there and ask to try one of the hand controllers in the shop and test it. If it now works you just need to buy another hand controller.

Otherwise send it in for repair
