SOURCE: Focus knob on Celestron NexStar 5 does not appear

Does the focuser move in and out when you turn the knob? If it does then go outside during the day timne and practice focusing on a distant object. Use the eyepiece with the biggest number written on it.

This will give you the lowest magnification-- which is easier to focus.

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.

SOURCE: 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.

SOURCE: Celestron NexStar 8SE shows No

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.
