Space Forum / Astronomy / July 2005False Color Photo of Titan
The cover of "Sky and Telescope" recently showed a beautiful, false color photo of Titan, in green, blue and orange. Did the colors delimit different spectral ranges or just different gray levels from a b&w photo?

I don't subscribe to anything, except what comes with various professional memberships. I don't have a telescope, and I live in a very "light polluted" environment. Someday, when I can afford a life, some things may be different. David A.

I'm a self-funded grad student, without a job. I haven't bought myself a nice treat for years, and my car is really starting to make some funny noises. I don't see these subscriptions as luxuries, but professional expenses. I think Scientific American, American Scientist and Sky & Telescope are indispensable resources for physicists and astronomers, and you're hurting your career if you don't get them. And hell, they're tax deductible. I'm in a heavily light polluted area (suburban Detroit), but I managed to find a camera shop that was clearing out their 2.4 in Meade telescopes for $50 and thought that was too good a bargain to pass up. There are a few things you can see, even in a light polluted environment. I've seen Saturn's rings, Jupiter's moons, the phases of Venus, sunspots, and the surface of the Moon. Next on my list are Mars, Mizar and the Andromeda Galaxy. A light polluted environment is not a reason to give up observing, it's just a reason to lower your ambitions. Soon I plan to show these sights to the neighborhood children, and maybe interest them in science. It's the cool factor that makes the difference, you know. What is it that's preventing you from affording a life?

Two kids, one that just became driving age, the other right behind. No college fund for either. My house has six computers (all but two home built), and feeding those beasts is a full time job.

D = David L = wife's name Z = eldest son's name C = youngest son's name AOL had all the interesting handles used up, by the time I gave up on CompuServe. David A. Smith |
