Hi All -

I was showing Mars to some friends, as I suppose a lot of us are lately(!)
and a question came up that I couldn't eloquently explain -

Why does Mars, or anyplanet, appear as "black and white" through a pretty
good telescope, while all the photos are in glorious color?

My weak explanation was that I "couldn't afford a color telescope," then I
tried to remember the rods and cones in the eye and all that. But I know
there is a better and shorter way to explain this...

Thanks!
Brian
