The night of 13th-14th September was quite steady so I took the opportunity to image Uranus in luminance and two different IR pass frequencies through a colour camera that is sensitive in the IR region.  I was able to image at 30fps for the luminance/IR cut and 15fps for the two IR pass filters.   In both the IR pass filters the result shows that one side of Uranus is clearly lighter than the other.
