I'm going to assume that you know you need to tighten the DEC clutch knob, and that this was already done.

There is an internal belt that connects the drive motor to the worm gear that engages the DEC assembly. Sounds like the belt has either broken or slipped off the pulleys.

The belt is model and size specific, so you'll need to contact Meade for a replacement.

You should eyeball it to make sure that's what it is before ordering anything.

Tip

You Just Bought an EQUATORIAL Telescope Mount!


Even though we warned you not to do this, you bought one anyway! Beginners should never buy an EQ telescope mount as their first telescope. It's too late now; so I guess we will need to teach you how to use it!

Equatorial mounts move in a way that seems not to very intuitive. Unlike the easy Alt AZ mount which moves up and down and left and right, the EQ mounted telescope seems to move in TWO dissimilar directions at the same time.

Additionally you must first polar align the mount on the North star Polaris before you can use it. SEE! we told you not to buy it!

Here are the steps to roughly polar align the telescope so you can use it. If it is motorized the single Right Ascension motor will keep the sky object inside the eyepiece for long periods of time. If you do not have a Right Ascension motor, the slow motion RA knob can be slowly turned to keep the sky object centered in the eyepiece.

Begin by leveling the mount and tripod. Move the entire mount and tripod so it is pointing roughly to North, as close as possible using the steps below or a compass. Don't forget to adjust for your magnetic deviation. My location's compass reading is about 5 degrees away from true North. This is called magnetic deviation. You can find your location's deviation on the internet. Then proceed with the steps below.

First, adjust the Declination to the latitude for your observing site. Declination is the angle that the scope is pointing UP, and it's the same as your latitude. For example Dallas, Texas is about 32 degrees North latitude, adjust the scope so the small indicator reads 32 degrees. By the way, the North star in Dallas, TX is about 32 degrees above the horizon. Your latitude matches the elevation of Polaris (the North star) above the horizon.

Second, either look through the polar alignment scope buried in the axis of the telescope mount, or look along side the axis, and get the star Polaris lined up in the cross-hair of the polar alignment scope, or as best you can by looking along the side of the mount axis, or lining it up using your compass.. This will put the scope to within about 3/4 of 1 degree of the TRUE North celestial sphere. This is good enough for VISUAL observation, but NOT good enough to do astro-photography..

Adjust the DECLINATION up or down, and move the entire mount left or right until you can see Polaris as indicated above, or it is lined up as close as possible.

Now you are roughly polar aligned. Now you can move the tube around by loosening the Right Ascension lock, and or the Declination lock until your sky object appears in the small finder scope mounted on top of the main telescope tube.(DO NOT MOVE THE MOUNT, and the counter weight should never be higher than the telescope tube) Lock down the scope in both axis and use the fine adjustment RA and DEC knobs to center the target. Again, DO NOT move the mount or tripod. The mount should still be pointing at Polaris.

This web site illustrates this procedure:
http://www.astronomy.net/articles/4/polaralign.html

also this web site

http://www.telescopes.com/telescopes/polaralignmentarticle.cfm

You should be able to keep an object within the field of view of the eyepiece by slowing turning the Right Ascension slow motion control knob-------- IF you are actually accurately polar aligned. Small adjustments may also be needed with the DEC slow motion knob since you are not exactly polar aligned using this rough alignment technique.

However it can be used successfully for visual observation. Your scope will now track the motion of the stars as they move across the sky.

Hope that helps you!

Clear Skies!

My declination adjuster works one way but not the other.


You must loosen the nut 1/2 way so you have travel distance in BOTH direction.

This is only for small movements. For larger direction movement you must loosen the adjuster and manually move the scope.

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.

I am struggling to set the telescope us as the


Is it like THIS telescope?
http://www.opticsplanet.net/konus-knonusmotor-130-telescope-1786.html

The focuser mechanism is at the FRONT end of the telescope. The Mirror is in the back-end or bottom of the telescope. This scope is on an equitorial mount, which means it must be POLAR ALIGNED in order to work. You can get a rough polar alignment by using the star Polaris (the North star).

We never recommend an EQ mount to beginners. Polar alignment introduces an additional beginner frustration with using the telescope. Read these web sites to get an idea of polar aligning a telescope.

Their are TWO knobs on the telescope that control Right Ascention and Declination movement. Declination IS your latitude, so the angle must be set to where you live. I am at latitude 32 degrees N --- so the angle is 32 degrees, which is where Polaris is above the horizon.

Holy man.. response is kinda slow. Good thing I tried it myself.

Sure as heck, you can leave the Right Ascension and Declination clamps tight while using the motors!
It makes a lot of sense, and many things much easier....
Thanks for the.. reply? lol. Just joking.
