Now, as for imaging at lower altitudes (assuming good seeing) you might care to look into somethig called an Atmospheric Dispersion Corrector. The lower the altitude the more air there is to refract light and the red and blue will begin to separate. The corrector consists of two prisms that are rotated with respect to each other to bring the red/blue back together. Using a red green blue filter set and refocusing might get a similar result but when capturing there isn't much time to fuss with focus. I read someone's opinion that the ADC would be best when using a colour video camera.

Hi Peter,
That looks fantastic! Only problem is it's quite expensive
Thanks for the link.
