I am still trying to get my QHY168c up and running, but ran into issues last week with randomized horizontal banding on every image. Didn't matter if it was a 5 second frame and focus image or a 5 minute light. These bands almost appear like interference bands, so I'm guessing they have to do with either USB interference or possibly the power supply? The camera didn't come with a DC power cord/supply for whatever reason so I had to get one on my own. The USB is running through a 3.0 hub into a 3.0 jack, but it also has the OAG camera running through the same hub. Any guesses? Thanks.
