Problems running the telescope control plugin

  • Dieter Koenig

    Has anybody hints or solutions for my problem using a Meade LX90 GPS controlled by Stellarium's Telescope AddOn.

    My configuration:
    - Meade LX90 GPS with Autostar #497
    - Profilic's pl-2303 USB-to-Serial (Driver to connect telescope and notepad.
    - Windows 7
    - Stellarium 0.12.0
    Actions (chronol. order):
    1. Telescope setup and alignment completed
    2. USB-to-Serial cable connected to my notepad
    3. Stellarium started and showing: Telescope connected b u t there is no crosshair to be seen
    4. Selecting any asoronomical object
    5. CNTR+1 (or "Move telescope to"-window) to go to the selected object b u t nothing happened!
    The simulation (telescope #2) works fine!
    For more informations see the appending excerps from the log files.

    I nolonger have 0.12.0 loaded and there is no problem with my 0.12.1 build

    It may be that the cross hairs are just invisible.
    Firstly load a dummy telescope as telescope 1 then see if the crosshairs work.
    If still not visible.
    Did it work with a previous version of Stellarium

    I tried it successfully (incl visible cross hair) with a dummy telescope.
    The control plugin indead works with my LX90GPS, with the above mentchend connecting cable and an older version of Stellarium, but unfortunatelly I can't say which it was. But what I know is, it runs under Windows XP.

    thanks, Dieter

    It may sound a little crazy, but if you can change USB ports on your computer and reset COM port in program, it may just work. A laptop I had did the same thing. Changing COM port solved the issue. Good luck

    Hello Anonymous,
    thanks for your hints. I tried it! I changed the USB ports at my laptop. Indead the COM port changed from COM4 to COM5.
    But unfortunately there was no difference. Still all seems to work fine, but again there was no crosshair und no reaction at the telescope when pressing CNTRL+1.

    As an alternave to Stellarium I also tried to control my telescope via the AutoStarCntrl program out of Meade's Autostar suite.
    It also works fine until the point where I is connected to the telescopes autostar. It says "AutoStaR Menu" and that's it! Again no reaction when pressing the approprate keys to move the telescope and no error message or comment!

    Something wrong with my telescope? But the native control via the Autostar box works fine!

    But the native control via the Autostar box works fine!

    This leads me to a possible cause of your problem.

    How is the PC-to-telescope cable connected to the telescope? Directly to the mount or to the hand controller?

    As far as I know, it should be to the hand controller.

  • Dieter Koenig

    To the AUX port of the telescope!

    And that is w r o n g !!!!!! I'm so stupid, sorry.

    Indead it has to be connected directly to the the hand controller!
    I just tried it and it works completely fine.

    Thank you very much, Bogdan
