After more than one year owning the scope, I decided to calibrate motors and then calibrate sensors, but to my surprise I can't calibrate sensors because I don't find the command.
As my Autostar is in Spanish and it is an awful translation, belive me, I said to myself "change the languaje and maybe you'll find it" (The manual is in English), but I CAN'T NEITHER CHANGE THE LANGUAJE!! 
I have contacted the dealer but he has to contact the importer and it's going to take a long time, Any ideas?
Regards, Fernando

Do you have to align first? what version of firmware do you have?

I don't know my firmware version, How do you get to it?
The scope works good although I'm loosing pointing accuracy, I alingned it and then searched for the calibrate sensors in the telescope menu and couldn't find it.
It has a calibration stuff that the only thing it does is moving fast both motors in one direction and then anything else, but I have lost alingment and have to realing. Anything about pointing to Polaris and the stuff should do to calibrate the sensors.
Thanks for watching, Fernando

The LX90 and LX200GPS (yes, also R also ACF....) menus are slightly different, perhaps someone with an LX90 can help here.
The Weasner ETX site has a good list of the menu trees for the Autostar 497.

Well-- maybe two suggestions--
1. Download the manual on the Meade web site for the controller (in English) and try to find it-------
OR
2. Download the latest firmware from the USA Meade web site-- in English-- and find it. After you download the firmware, I would do a full RESET and re-enter and-or check Site, Time, Date, Daylight Savings Time, and retrain again from scratch. I am using firmware version 43Eg

Done from the beginning, they were so nice that they sent me the LNT, not GPS mnual, so I had to download it in English. So now my manual and my handpad don't talk the same languaje, what makes it more difficult (belive, there are things very funny with the translation). There my other question, if somebody knew how to change the languaje.

I haven't got the cable. For guiding I bought the ShoeString GPUSB and the APM mdule, so I guess I cannot update the firmware.żNo?
Maybe the reset, but do you think I'm going to find then the calibrate sensors?
You have that option, I suppose.
I haven't recieved feedback from the dealer yet.
I'm so determined to change the languaje and calibrate sensors, if I can.
Thanks so much, Fernando

Asturies,
The manual for your scope can be found at:
http://www.binoculars.com/images/pdf/MEAD277.pdf
If you look at the menu for the Autostar on p. 24 you'll see that the LX90-ACF menu does not list the Calibrate Sensors function although it is discussed on p. 29. In your Autostar menu, cursor down from Object to Event to Guided Tour and on down to Setup. Hit Enter. From there you can cursor down just past Reverse Up/Dn. If you have the option for Calibrate Sensors, then it will be the next option that you can cursor down to. If you don't, then the next entry you see will be Quiet Slew. (I have the LX200 and it took me a while in the menu to finally find it.) Good luck.

I had that same problem with my 10" LX90. The cause was that I had disconnected the LNT module. If that module is disconnected, the Calibrate Sensors command doesn't come up. I reconnected the LNT module and was able to calibrate the sensors.

Well, the problem is not the manual, the problem is that when I go to the telescope settings the "calibrate sensors" option doesn't appear. It could be due to what GeorgeNC says:

But, the LNT module was perfectly connected because I tried to calibrate sensors after the scope aligned in equatorial mode perfectly.
It has to be something wrong with the firmware or the like, but that is a problem since I haven't got the cable and I don't feel like buying it. My laptop hasn't got a serial port anyway.
Vendor is missing.
I'll have to wait a few days, I'm going to travel for five days, so as soon as I come back I'll try it in the 4M forum.
Hope somebody has had this problem and solved it. (Does this sound evil?  )
Regards, Fernando

Yes you will need the "cable" to update the firmware and preferably a regular serial port on the computer-- if you don't have a serial port then you need another cable "a serial port to USB adapter cable" -- www.scopestuff.com sells both cables--

Could a flat LNT battery be the problem. Just Guessing.

When my battery dies the only thing that happens is the TIME and DATE may not be correct-- setting both manually makes the scope usable again. (for automatic alignments)

Hi there, sorry for posting so late, I've been doing camping a few days. I have recieved feedback from the dealer. He has contacted Meade importer and they told me where to find the calibration sensors; set up, telescope, calibrate... I told him that I already knew that, the problem is that the last and important part didn't appear 
He will check again. This saturday I'll try it again in alt-az, althoug I don't think this is the problem, it should work in equatorial also.
I have GPUSB and the APM module, but I don't think I can change the firmware with that.
In the end I'm going to have to by the USB to serial adapter, so more money spent  It's our fate.
If I find the solution I'll report, promised.
Regards, Fernando

Ummm, yeah I think alt-az matters a lot!
Sensors like level-north are ONLY for alt az because the polar home position is NOT level like it is for alt-az!!!!
So there is no need to calibrate somethign that is disabled in polar mode anyway.... Not too shabby, Meade programmers, eh?
I hope that fixes your problem, the solution is, I believe, that you do not need those sensors for polar mode. What is it about these scopes (and Celestron is probably no different) that if something works like it should, customers immediately blame Meade for giving them a faulty scope....

Well Joseph, you could be right, I don't know. The bad thing is that I went to our dark site with my astromates last saturday with the intention to observe the whole night (nothing about photographs), so I decided to go alt-az and check if I could calibrate my sensors but from the beginning to the end of the night GOTO's were so dead center (like never before)that I forgot completely about sensors.
And I had the 80mm Equinox, the counterweights and the microfocuser on the scope, so it was pretty loaded.
Probably one of my best nights watching the wonders of the cosmos. It's great when electronics work fine.
We even saw Mayall II the globular cluster of Andromeda (by courtesy of the Tom Trusock's Small Wonders guide)
I'll have to mount in the garaje and make a fake alingment an see if it has the calibrate sensors in alt-az.
Regards, Fernando

I can check my ETX Autostar 497 which has some pretty old firmware if you really need to (have to get it out of the closet)

Yes, you are right, but the problem arises when I want to do astrophotography and need GOTO's in the middle of the 350D chip and I'm in equatorial mode.
Watching, there is no problem, in the end I find the objects, but through the camera's viewfinder it's another stuff, and I lose a lot of time (that mainly I don't have).
Well, I´ll keep doing research on this.
Thanks for helping, Fernando

Well I suspect you won't have the sensors option in polar mode.
You might want to try high precision mode, where you say you want to GOTO M42 (for example) and it tells you center a star near your desired object (usually a star that will be viewable in your camera's viewfinder) and it slews the rest of the way from that nearby star.

Thanks Joseph, it's what I've done but when it is not in tune it is very difficult to know where it wants to go. Sometimes there are not bright stars in the vicinity or I dont realize which one it wants me to aim.
I'm going to begin to mount the smartfinder, I tested it the first time and never used it again (I don't even use the finderscope most of the time) Maybe it could help.

I'll check this next week, on Wednesday I'm going back to my hometown for a week, so I won't be able to check it.
