    Hello all!
    In my old ST-402ME have the trouble: the shutter(internal filter wheel 4-positions) don't go in correct position and remain in middle way between open and close during poses. Regardless of the ambient temperature.
    I bought this camera with this bug... Camera used generaly for photometry of variable stars.
    What if I remove the filter wheel altogether? How will this affect the quality of photometry?
    Or i need investigate and solve this bug for getting good frames?

    You need the wheel - it's also the shutter.

    Check the center screw and make sure the wheel is mounted properly, and the screw is tight (but not too tight).

    If you can't get it working, then Bill @ SBIG Service & Repair will be able to help you. bill@sbig.com
