btw the reason the channels all look different is that:

- they focus at different places due to the presence of barlows etc (ie glass) elements, so in a colour camera you can't get them all in focus at the same time.

- The earths atmosphere has a more severe blurring effect on blue, but red comes through mostly ok.

- the planets themselves have more or less detail in each of these colours due to the colours being associated with clouds at different altitudes, on jupite the blue colur tends to be associated with very high altitude clouds that are less defined than the low altitude (red) clouds.
