This is cross-posted with the Maxim team as I am not sure exactly where the problem lies. I am moving to a Mach-1 mount and got it to work last night but had problems with the SBIG STT-8300M and Maxim. I downloaded the driver checker and latest drivers as well as CCDOps. Camera connected fine but when it takes images they come out black.... I recall the earlier horror show I had with the camera and drivers not moving the shutter right.... I was an early adopter of the STT 8300M and tried to keep the original drivers once they worked. Could newly downloaded drivers be the issue? It was too late last night to check everything. Luckily (actually not luck but experience) I have the computer from my old mount with all the settings and drivers. The new computer is the same except running Windows 10. I can troubleshoot by switching out the computer, but is there an issue with the driver? I really should post this on the SBIG Hardware page, and probably will (here I am). Tim, I am still on Skype and have your Skipe handle active. Will send you a note there. I am at the office but will be at home later today where I can troubleshoot.
