I had to replace the hard drive in my laptop and so I am having to re-install everything again. It is a Lenovo i7. It has the same operating system before I replaced the hard drive, Win 7 Professional 64-bit. As part of the re-install of everything, I installed ver 6.3 of ASCOM. This is about the ST-i camera. The camera has not been in service for 6 months or so, but the last time I used it (on my spectrograph to guide with) it was working. I am guiding with CCDOPS. When I launch CCDOPS it recognizes the camera and gives me the information on it when I click on the button to get camera information. So, I know it is making contact with the camera. However, it will not take an image. I reran the Driver Checker64 with the camera plugged into the laptop. This involved downloading the drivers and updating them. It still will not take an image. I then removed all the drivers and again downloaded and updated them. It still will not take an image. I checked the Firmware and it says it is up to date. Previously I had re-installed CCDOPS from an older disk that came with my ST-8XME camera. Since it was an old disk, I then re-installed CCDOPS from the disk that came with the ST-i camera. It still will not take an image. I then tried taking an image using CCDSOFT. It made contact with the camera but it still will not take an image. I get the same uniformly black (gray after a dark sky subtract) that has no granulation from pixels. So, I know the problem is not with CCDOPS. Finally, I switched to another USB port on my camera, which shouldn't have made a difference because the camera is being recognized with the other USB port. It still will not take an image Could this be a shutter problem? It does not seem likely because the image is entirely and uniformly black, no granulation from the pixels at all. Does anyone have suggestions of what could be wrong?
