Question about Meade LX200GPS Telescope

1 Answer

Backwards? I removed a 10" LX200 GPS scope from the mount to transport it. I reassembled it and now it wants to over run the hard stops to the point of motor stalling (I keep the locks loose so gears aren't damaged) and the Dec seems to want to run continually. QUESTION: Is it possible to assemble the scope to the mount backwards or in such a way as to create a reversed sensing by the circuit board? Any help would be outstanding it's driving me insane. RW

Check the Autostar controller for a stuck direction key.

Ime looking for a meade LX200 users manual that comes with the scope


Most Meade manuals are available on their support site: http://www.meade.com/support/manuals/ . Scroll down through the list for the LX200 series manuals (in the Telescopes section). The LX200 manual is listed as the LX-200 Classic. The current link to this manual is http://www.meade.com/downloads/dl/file/id/10/product/0/lx200_classic_manual.pdf .

I hope this helps.

Procedure to set up a meade 12" LX200R on


It's pretty much all spelled out in the manual. Here:

http://www.meade.com/manuals/TelescopeManuals/LXseries/LX200-ACF_manual.pdf

You should train the drives, and purchase a separate 12 volt power pack with the correct cigarette lighter style power cable. Calibrate motors BEFORE you train the drives with the same power source you will use outside at night.

If this is a GPS model-- and new--- I would execute a RESET on the hand controller-- calibrate motors and train the drives and take the scope outside and get a Satellite link and do a two star automatic alignment.

Make SURE you are centering the correct alignment stars. By the way TRAINING must be done in alt az mode before you put the scope on a wedge-- it cannot be done in polar mode.

You have GOOD power? You can try and replace the hand controller cable--

I would also Calibrate motors, and retrain the drives. But re-training must be done in alt az mode.

Luminova 40114675 (675 x 114mm) Telescope: cant veiw anything out of it...


This is a REFLECTOR style telescope. The end with the focuser and the eyepiece is pointed UP. the mirror is on the bottom of the scope.

Take the scope outside during the daytime and practice focusing on a distant object using the eyepiece with the LARGEST number written on it.

The PICTURE shown above really makes me laugh. The scope is mounted BACKWARDS in the picture above, and is pointed toward the GROUND not the sky. Even FIXYA puts them on the mount backwards!

Look at this picture. See how the eyepiece and focuser are on the end pointed toward the sky. The MIRROR is the BOTTOM of the telescope:

I believe your scope is mounted backwards just like the picture FIXYA applied to your question!

You have a standard lx200 problem. If you transported your scope a lot with the drives "locked" it damages the RA and DEC drives. If you keep using it, the motors burn out and start drawing too much current. This sometimes blows the motor driver chips on the motherboard which are getting very rare.

The burned out tantalum caps can be replaced with better aluminum electrolytics very cheaply. If the ones in your Autostar burned out, they often burn up the ribbon cable. Also, they often take out U11, a 74LS14 chip on the motherboard. Also a cheap repair. You should take the Autostar apart. If they are burned up, it will be obvious. If your ribbon cable survived, you should replace the caps with aluminum electrolytics. I believe they are 6.8 uf.

So, if you can work an ohmmeter, measure the resistance of the two drive motors with the plugs unplugged. If it is about 14 ohms they are ok. If they are about 3 or 4 ohms, they are toast. Check the worm drives for end play. If there is just a little, you can adjust them. The battery jack on the control panel often breaks the solder joints on the board, causing one of the problems you describe. You can check that and replace/resolder as necessary. The on/off switch often fails and gets intermittent. These are also cheap and can be replaced. I don't repair these for a living but I repair a few of them for friends in the club. These are pretty common problems.

Meade LX200 10" - RA Gears slip when mounted on wedge (Milburn)


The problem is the addition of the 80mm telescope to the assembly. The telescope is now out of balance, and places extra weight off-center as the position chages. Too great an off-balance will cause the main gears to 'jump' the worm teeth. The solution is to restore balance by adding counter weights as needed. Loosten the axis locks (carefully) and see which direction it wants to move. To balance my LX, I used a small bag with lead buckshot to determine how much weight was needed and where to achieve balance. Then I added fixed weights to the mount. Once this is done, the scope should track correctly.scopestuff.com has balance kits at reasonable prices.
