Can I just swap out my meade 492 motorized mount remote for a used 494 autostar remote or 497?


It depends on which model Meade telescope you own-- you never said?

Yes you can swap a 494 for another 494-- but we need more information to be able to say a 497.

I have a broken autostar 2 telescope controller and need a replacement but can not find one in the UK


Many Meade dealers can order you a new hand controller, either Autostar II, or the 497 controller. Contact a large telescope dealer in the UK, or you can order direct from Meade here:

I am trying to repair the motor drive in the fork of the 125 model, and would like to aquire a repair manual. the motor in the base runs fine, but when I pulg in the Auto Star paddle from my 6 inch...


Your problem may not be the motor?

Is this a 497 hand controller? If it is check the TELESCOPE TYPE in the controller. It should read ETX125. You cannot just switch controllers. The controller has been TRAINED for the other scope.

To switch it you must do a RESET, Calibrate motors and then train the drives. These "values" are stored inside the hand controller. If you move it to another type of Meade telescope you must RESET and do Calibrate sensors and Training again.

The dis-assembly pictures are located on the Mighty ETX web site here:

I have a meade lx90 8inch 3 years old with autostar 497--when i try to raise the scope up it keeps drifting down also having problems with intermitant slewing on set up-both motors working ok


This is called "rubber-banding". Your scope needs to be re-trained.

So, setup a target during the day at least 100 feet away from the scope (200 feet would be better, Calibrate motors using the same power source you use at night, and Train Drives. Later after dark, do a Calibrate sensors on Polaris.

You should train drives about once per year, and calibrate sensors about twice per year.

You may want to update the firmware before you Train Drives. The latest version is 43Eg available on the Meade.com web site. You with need the Autostar Updater Software also available on the Meade web site under Customer Service---- Downloads. Version 5.9

I have a frozen autostar 497 handbox, can it be reset or saved? While doing an update, the updater program window asked if the handbox was in ''safe mode'' (I think it was something like that), I clicked...


Turn off the scope and plug in your computer update cable.

While holding down the ENTER key and the Scroll DOWN ARROW key on the bottom, turn the scope on.

The controller will go into Safe Load mode-- redo your update again.

ETX-125 Autostar controller not working


I assume the small red light on the power panel is ON. ???

If it is the scope is receiving power--- check to make sure the cable from the hand controller is plugged in properly-- jiggle the cable to see if you have a loose BAD cable. Before you panic --- try another cable or reverse the ends ---

Before you buy another hand controller try a new cable-- scopestuff.com sells a nice long flexible one for the 497 hand controller.

The telescope doesnt go up it goes down


I assume you are using the 497 hand controller? Planets will always be a little bit OFF since their orbits are calculated. You should be able to see Venus, Jupiter, and Saturn as a disk-- the other planets are very tiny and can be mistaken for a star.

Use the Automatic alignment feature and center the brightest nearest star. It will not be in the eyepiece. Be sure you calibrate motors, and train the drives, and the time, and date and site are accurate.
