Question about Meade LX200GPS Telescope

Meade LX200GPS The scope does not complete the 'Auto Alignment'

Meade LX200GPS with latest 4.2g update. The scope does not appear to complete the 'Auto Align' at start up correctly. Specifically it will get as far as 'Tilt' but will only check one plane, roughly north. The instructions suggest that the scope should be automatically checking on 3 planes, which it has done in the past. I have reloaded 4.2g but this did not change the behavour. The scope will then take a GPS fix and all works well as far as making the two star alignment and slewing with very good accuaracy to anything I care to look at. Any ideas. The upside of this behavour is that the Auto Align feature does not take as long and there seems to be no degrading of pointing accuracy or any other issues. I should point out that I always level the telescope base before auto aligning.

Once the scope has taken a GPS fix and knows TIME, and SITE, and you do a two star alignment your alignment stars overide any automatic alignment issues.

You could turn off the GPS put in Time, Date, and Site, do a two star alignment and everything would be fine. Centering the alignment stars is the "trick". Apparently the scope also finds NORTH OK, or the alignment stars would be way off. Since you pre-level the tripod already the software can FAIL on "tilt" and you still get good gotos.

I would not worry about it, especially since your gotos seem perfectly fine.

Hi I live in the UK about 350 miles away from the


Meade may or may not sell you the board. Usually they want you to return the scope for repair.

Call them and explain that you know how to fix it and only need the part. Ask to speak to a supervisor if you at first meet any resistance.

My 8" LX200GPS won't turn


Then it is an internal circuit board issue. Something is either unplugged inside the scope base-- or is burned out. Meade can repair these call them:

My meade LX200GPS can't track the stars? wheater the bad weather of observation points will affect the accuracy of automatic alignment? how can I improve the tracking


You must Calibrate motors using the same power source as you use at night outside, then do a TRAIN drives. Some of these scopes also have a Calibrate Sensors -- and some do not.

Then do a two star alignment and center both alignment stars. Daylight Savings Time = Yes right now in the USA, check that it is set to YES.

I have a meade lx200gps 10" scope. The ra up is not responing. the down is working only. After initializing and fining north the auto star says stalled motor.


Do a calibrate motors and make sure you are using a separate 12 volt power pack or BRAND NEW internal batteries. All goto scopes work better with smooth, regulated power. The internal batteries will NOT work well for very long.

The Calibrate motors routine adjusts the motors for the power supply being used.

GPS couldn't lock on satelite signal


There is an internal battery, check and replace to make sure it is new.
Any obstructions like tall buildings where you setup the scope?

It is possible to bypass the GPS, just manually enter Time, Date, and SITE, and do a two star alignment.

Meade LX200GPS 16" out of calibration?


Before you panic I would update the firmware/software on the telescope. With an LX200 interface cable you can upgrade the software in your telescope from your PC by going to Meade's web site at www.meade.com

Download Meade's ASU (Autostar Update Utility) and the latest software for your Autostar II absolutely free. You can also use the ASU to add Comets, Asteroids, Satellites, and User Objects to your Autostar II with a few simple clicks of the mouse.

I believe you can get the manual here.

Can't communicate with serial port


You need the Meade cable and if you do NOT have a serial port then you also need a USB- to serial adapter cable.

Keyspan makes a good USB0-Serial adapter cable.

Check the PORT number in the software and make sure it is the one the computer is using.

Problem with lx200gps meade telescope


It might be a voltage or electrical current problem. Make sure your DC power supply is between 12 and 14 volts. Make sure all electrical connections are tight. Where the power cord plugs into the connection panel, make sure the center pin on the panel fits tightly into the plug. It is a Radio Shack type "N" plug. If tou still have a problem, remove the bottom plate from the scope base and make sure all the connectors are properly seated on the circuit board. Check the connector on the end where the black and red wires are. That is a main power connector and if it is too loose it will not conduct enough current. There can be enough voltage drop that the drive motors won't operate, or they will and the scope will slew uncontrollaby. Be careful handling the wires so that you don't damage them. Good luck, Dave

12'' LX200 classic


Check the time clock battery - it is behind the front panel. If it is dead, then the clock is off, and the alignment will not complete properly. Regular watch lithium coin cell.
