Hello! I run my ST-402 with ST-i using SGPro for photometry. Problem: The shutter stays closed during the exposure time and opens when the exposure is finished. Last night, the ST-i stopped obtaining images during guiding. I brought it in and ran it under CCDops with a powered hub on my desktop. When I grab an image, the shutter stays closed for the exposure time and then opens when the exposure is finished. This repeats each time I grab and image. What I've tried: The camera connects fine. The shutter clicks on connection. I've run the current DriverChecker a number of times. I've uninstalled and removed the drivers and searched for and removed any hidden drivers for the camera, and restarted the computer. The firmware in DriverChecker states firmware st-iusb .bf2, camera version 2.37, release version 2.37, and that the camera is current. I would appreciate suggestions on correcting this problem. Best regards. Mike
Thanks. It is Working now. I guess multiple reloads eventually solved the problem. I put it back on the scope, and I'll see how it works under the stars. Best regards. Mike
