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.

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!

How does a compass always point to due north?


"Due North," by definition, is the direction towards the earth's north pole; or, visually at night, towards Polaris, the north star. Therefore, compasses generally do NOT point towards due North but, rather, point towards "magnetic north," as the other responder described, which is a variably located at some distance from True North, depending upon where the north-locating compass is situated on our planet. In most circumstances magnetic North is close enough so that people are willing to accept it as North in general terms. However, depending on your location, and upon seasonal changes caused by Earth's wobbling rotation (called precession) true North can be many degrees off from magnetic (from your compass's) North. In those cases true North must be determined using declination charts, which will tell you how many degrees to add or subtract on you compass in order to determine true North by the Magnetic North your compass is pointing to. For example, if magnetic North is 10 degrees west of true North at your compass's location (that is, your compass is actually pointing 10 degrees to the "left" of North), then you would correct by considering the +10-degree bearing point on your compass dial as True North--and, likewise, add 10 degrees to any bearing line you happen to determine using your compass. You have one other way of finding True North, which is celestially, by sighting towards the Pole star, aka Polaris, aka the North Star...that is, providing that the sky is UNcloudy and unsunny enough for the star to be visible. Of course, that only works for those located in the morthern hemisphere. Those south of the equator have a "south pole" star but it is not as accurate as Polaris in the northern hemisphere.

I have an Action Sports T16 treadmill and we have just relocated home. When I plugged it it, the red light comes on to indicate it has power but I hear a ''click'' and the dashboard doesn't light up or...


The vibration of the move may have loosen the connectors. Unplug unit remove motor shroud you will see the motor control board pull and reconnect all connections also check the connector in upper electronics then on unit see your display works and see if you have motor and belt movement.

Compass is no longer pointing North


I had the same issue. I found that if you re-calibrate the compass the same way you did the first time, then it will act properly. I've had to do this a couple of times and it works.

Cmpass (COM)
The integrated compass tells you the direction (e.g.SSW for south­southwest) as well as the number of degrees. To determine a direc­tion,hold the watch horizontally with the 12 o'clock position poin­ting in thedirection you want to know.
General information about the compass
The compass always points to the magnetic north pole.Maps are always drawn in alignment with the geographic north pole (verticallyupwards at 90 ). The declination angle denotes the deviation between themagnetic north pole and the geographic north pole. This deviation depends onwhere you are located. To obtain exact results, the declination angle must beentered into the compass.Remember to change the angle when travelling abroad.Within the UKthere is no need to change the angle because deviati­ons are only slight.Overleaf you will find a table showing the declination angles for a number ofcities around the world.A fault has occurred if the display shows"ERR" while taking a direction or calibrating the compass. Thecompass must be re-calibrated (refer to section after next) .

C10-NGT RA+DEC clamps and the motors


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.
