LX200 GPS problem

My scope has been unused for 3 years now. When I fired it up everything appears to be just fine but then it begins setup anytime it wants and turns all the way to the stops. It then tries to bypass the stops so I immediately shut it down. I have attempted to fix by resetting but it still doesn't help. It scares me that it will strip gears so I need some assistance. Meade has no suggestions. How can I find directions? Would reloading ASU II help? It now has 3.0i....Any assistance is appreciated,Rick

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

Problems with my LX200 Classic

Problems with my LX200 Classic version

C1 and C2 are on the input of a voltage regulator. The fact that they burn, could mean that their voltage rating has been exceeded (check the voltage across them), or that age has caused their failure. The classic uses about 18 volts into the power panel - see that it is not higher than that. The handpad would not be a cause for this to happen as it is not the source of the power. Replace the caps with similar ones, but with higher voltage rating - 50v is fine. But check your power supply first!

Calibrating & Aligning the Meade 10" LX200 GPS Telescope in the Southern Hemisphere

Do a Calibrate Sensors Do a Train Drive in RA and also DECThis makes sure that the scope is calibrated properly. Do an AUTOMATIC ALIGN when asked to center star, look for the BRIGHTEST star that is close to the scopes field of view. It will be that star you need to used the arrow keys on to centre it in the scope eyepiece and press enter. This star can be as much as a HANDS distance away from the centre of view If you cannot identify the star it is asking you to use, press the SCROLL DOWN key to choose another star, keep doing this until you see a star you recognise.That's it!You can also hold down the MODE key for about 4 seconds and scroll through the scope info. Make sure you have the correct location coordinates ( Lat/Long) and the correct time set.Select a bright object first such as a planet and GOTO it. Once you have manually centered it in the eyepiece, press ENTER and hold it for 6 seconds, the handset will say " Press ENTER to sync", press enter and you have updated the scope with the coordinates of that object.

I have an older Meade LX200 GPS with autostar II handset. The telescope was working fine and last night I got an error message on the handset "Error: Inv. Heap" and the telescope locks up with no further handset or RS232 communications working. I powered the telescope down. When the telescope powered back on, I got the welcome to Autostar message and the firmware version 4.2g. It then changes to a message "Reorganizing" and then generates the Error: Inv. Heap". Meade says to "Reset" but the system locksup before getting to that point in the bootup. Any input on how to resolve this problem?

You may have Corrupted firmware in the hand controller- that's why they want you to do a RESET.You might have to reload the correct firmware to fix this problem.I believe if you hold down the ENTER KEY and the SCROLL DOWN arrow key and then turn on the scope you enter SAFE LOAD where you can reload the firmware.

GPS not working

Nope! Sounds normal. The GPS is used as the surface point and time refrence, but it still needs the star fixes to orient the axis. 2 star alignment is generally for Alt-Az mounting, while you can use 1 star for rapid setup on a permanent equatorial mount.

Problem with start up on telescope

Most probably, flat batteries. Autostars go berserk when batteries are even a little low. Try it with a mains power adaptor instead. Otherwise, maybe its a dodgy curly cable, broken Autostar, broken control panel or Autostar firmware needs reloaded

I have a CPC11GPS telescope that was working the last time I used it, which was 6 months ago. It is in NEW NEW condition. I pulled it out last night, turned it on, allowed the system to align itself using the GPS system aboard. I then tried to center the first star using the RA and DEC directional buttons. The Dec buttons moved the telescope up and down, but the telescope would not move in RA. I also connected the scope to my SKY program, it also moved the scope in Dec, but not in RA. What could have happened since it was last used? The only previous problem I encountered was alignment and intermittent RA movement, I sent the scope to Celestron, who worked on it and returned it. Those problems were never corrected by Celestron, a year ago.

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.
