    Hi
    My FW8G-STXL on my STXL 11002 don't give me any stars on the chips!
    The camera just returned from Bill after a massive repair, and after mounting it on the train again, I want to calibrate the guider, but negative, no stars at all, and no warnings.
    Any solutions?
    All drivers are updated.
    Any settings file I can give you?
    Thanks.

    What software are you using? Do you have it set for external guide head?

    Are you getting all zero pixels? Or is there noise in the frame? Is the shutter actuating?

    I have tried with ACP, TheSkyX and latest Maxim DL, external guider, I haven't done anything in the setup since it ran ok.
    There are noise in the pictures. Is there a shutter on the filterwheel guider?

    Looks like a normal dark frame.

    Yes there is a shutter in the guide camera.

    First update the firmware, drivers, and application software to the latest versions.

    Other things to check:

    Make sure the mirror isn't positioned too far out and is completely vignetted.

    Make sure the focus isn't way off. If it were you might not see fainter stars.

    Shutter is not actuating for some reason. Remove the camera/wheel assembly from the telescope and look in the front. Take a light frame with the guider - the shutter should open so you can see the guide chip.

    Aim the telescope at the moon. Should see some light!
