Diffraction, I am the proud owner of two SBIG STF-8300M cameras. I bought a second one, used, in case my primary one failed in the field or at a star party. Well, my primary one did fail! I was getting horizontal bands when imaging in Sequence Generator Pro (SGP) (image attached). It came from out of no where. The recommended solution online was to make sure the latest drivers and firmware are installed. I work in IT, so I have the guts to update the firmware. It appeared to work, but then I began to get intermittent Vertical Lines (image attached). Now, the Vertical Lines are permanent. I confirmed with CCDOps (image attached). One thing that might help trouble shoot is after I performed the upgrades, SGP took the camera temperature to -40 Degrees a few times without me noticing even when I had it set to -20. Troubleshooting Technicals: - Windows 10, 64 bit - CCDOps 5.66 Build 1-NT - SGP SGP v 22.214.171.124 - sbigudrv.dll 4.99 Build 6 - sbigu64.sys 126.96.36.1998 - stf-8300usb.bf2 2.63 - stf-8300ga.bf2 2.25 Images of screenshots and versions attached. I hope it isn't a brick! Please advise. Sincerely, John Sojka Jr.
