    Is there a way to find out the speed used for shutter movement? Better yet, can it be changed?

    What do you mean by "speed", and why does it matter?

    SBIG shutters are designed to provide equal exposure across the chip, regardless of how fast they move. The minimum exposure time for each model is listed in the specifications.

    I mean by speed, how fast the shutter moves across the ccd array. We have several cameras in-house and I am suspecting that the shutter in one of them is acting up. Is there a way to measure the actual speed?

    The only thing I can suggest is to look in the front of the camera and observe them operating.

    The shutters on all cameras except ST-I and guide heads are based on stepper motors. If for whatever reason they have insufficient torque to actuate they will simply stall. They will not "run slow". Any problem with their operation would be clearly visible to the eye.
