Received a new STT-8300 camera today with the self guiding filter wheel. Installed the filter wheel & filters. Plugged it in to set it up and test everything on the bench before taking it out under the stars. Had previously updated the drivers on the computer. - sbigudrv.dll 4.88 Build 11 Connected with latest version of CCDOps using the SBIG supplied USB cable. The shutter would work correctly maybe once after the camera is connected. Then it will get stuck part way open obstructing the detector every time [ 1 sec, 2 sec. 6 sec., etc.] and then not fully close. Shut down the camera, checked all the software settings and restarted. Same thing. I would get a pop up window advising of "Shutter error". Shut down and re-started. The shutter is now stuck and doesn't rotate at all and makes a disturbing sound. The filter wheel seems to be working OK. The indicator light on the side of the camera does not light up. Checked the firmware with the driver checker utility - for sttga.bf2 it tells me the camera version is 2.58 but the release version is 2.61. This is surprising because I would have thought that a new camera would have the latest drivers loaded. Hopefully someone can help me get the camera shutter working. I have had 6 previous SBIG cameras and this is the first one that didn't work correctly out of the box. Did I mention that this is a brand new camera?
