Looking at some of the bias frames, and comparing high speed and low speed download, there is a big difference in noise. Much less noise with low speed download.. STD about 15...compared to 50 with high speed download...I think this difference is do to my hub/ports rather than the camera itself...What STD do others get?

Always use low speed download when imaging. Also pause guiding if you use the same USB cable to guide the mount through a hub. Finally shield the S-Video cable that goes from the DC-101/2 to the camera.
