Question about Celestron NexStar 4 SE Telescope

1 Answer

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 problem within the telescope itself. I have to say I am not at all happy with Celestron

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.

Testimonial: "Thankyou for your response. The batteries are fresh. Have also tried powering up with an AC Adaptor. Neither worked."

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.

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:

The hand held unit will iluminate and I can move the telescope withe the up and down buttons but nothing comes up on the screen.

You mean you cannot find anything in the sky looking into the eyepiece.

READ my GOTO Tips on my profile page, also read the manual again. These must be Calibrated and TRAINED and the TIME, DATE, and SITE must be correct in the hand controller.

Also you must align them on two KNOWN stars once you setup outside and level the tripod.

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.

No power hand held no light on display

Make sure the batteries are good. The cable to the hand controller may be bad. You can get another cable from either Celestron or a local dealer.

If a new cable does not fix it, then either the hand controller is defective, or something on the internal circuit board. It must be returned to Celestron for this type of repair.

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.

I have a celestron nexstar 5 the begins to move on it own

Many times a bad cable will cause this. Also low batteries can cause this.

Contact Celestron and order a new cable. Use an external 12 volt power pack.

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.
