The clutch is not engaging in RA. Maybe the gears are not actually meshing together? A loose worm gear?

You can open it up and look and see if anything obvious is loose. Otherwise it's a trip back to Celestron.

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.

Not able to see anything would like how to use cerlestron EQ 114


This is a small reflector style telescope on an equatorial mount. The mount and tripod must be polar aligned in order to be used. Read this:
http://arnholm.org/astro/polar_alignment/index.html

Simply pt the eyepiece with the largest number written on it into the telescope, take the scope outside during the day time and practice focusing on a distant object like a building.

Celestron's manuals are located on this web site-- find your scope and download one for free:

First thing to do is to buy a new hand controller cable from Meade, If this does not correct the problem then either the hand controller is defective, or something is broken inside the scope.

Cables are not expensive, call Celestron:

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:

I just bought an Optus 553 telescope and the instructions are not in English. Where can I get operating manual and set-up instructions please? I live in Spain.


Sorry, but that is NOT a major brand of telescope like Skywatcher, Meade, Celestron, Astro Physics, and so forth.

You will not find a manual anywhere. Try to locate a local Astronomy club and get the members to help you with the scope. Most clubs welcome new members and will help them.

Celestron 114EQ polar setting and Equatorial settings


The ALTITUDE adjustment matches your LATITUDE. I live at 32.5 degrees North latitude. So the scope is first adjusted to 32.5 degrees UP.

Then the Right Ascension is point to Polaris the North star by MOVING the entire scope and mount.

Read my Equatorial mount TIP on my profile page, and read this web site.

Celestron advanced gt declination motor does not working


You did tighten the clutches?

If you did the DEC gears are either loose and not meshing or have broken.

Dr. Clay in Arkansas can repair this scope but it would cost several hundred dollars-- Celestron will probably sell you the parts to fix it. Here is their web site. You can also return the mount to them for repair.

Problem with Celestron Starseeker 100mm refractor


Could be several different mechanical or electronic issues with the scope.

From a dirty encoder disk inside to a bad motor clutch.

Best to return it to Celestron for repair.

GoTo Problem


Be sure that the telescope is configured for EQ SOUTH mode to tell it is in the southern hemisphere. Once a star alignment is completed NEVER manually move the telescope. Use only the control panel to slew. Everytime the telescope is move by hand, the motors do not know it has been done, and assume it is still pointing at the old direction. Check the manual for setup.
