    Rick - Cabrillo College Astronomy Chair: I've got a problem - "Shutter Error". It's with our SBIG ST4000xcm camera, which we've been happy with for 10+ years or so. We've not used it at all for a couple of years however, it's sat in it's secure company-built black case at the observatory during this time. I've got a new Trio Win10 tablet computer for dedicated use solely on running CCDOPS and our SBIG cameras in the field. I fired it up first at home, and all seemed well, and I anticipated a great night of shooting come PANSTARRS and the Helix Nebula. But in the field (hills of central California, dry mild night at low 60's F temperatures), after connecting to a good full-charged hefty gel-cell 12v battery, and separate fully charged new battery to keep the Trio tablet happy, I got the camera going, put it in "focus" mode, it downloaded the first few focus frames (1 sec images), and then it froze with "shutter error". I tried powering camera off/on, re-booting computer, re-seating all connections, looked at the window above sensor, all without trouble. But still, after putting in 'focus' mode (or 'grab' mode too), it would work for less than a minute and then 'shutter error'. Sometimes I'd get 3 or 4 images, sometimes 1, once I got 0 images before the error. But nothing resolved it. The drivers and CCDOPS were downloaded just a couple of weeks ago and seemed happy. The one thing is that the firmware has never been updated, so it's ancient. Could that be a problem?

    Hi Rick,

    Sorry for the late response.
    You should get in touch with Bill Lynch about the shutter error. He knows the older systems very well.

    I would test it with different computer, not Trio tablet and classical power supply.
