Over the last several years I bought several CD's with astronomy themes, but don't use them. I found them in a box in storage two weks ago.
(1) "Through The Eye of Hubble", Hubble photos, screensaver and wallpapers for Windows or Mac. NASA. The disk is perfect but the plastic case is cracked several places. $6.00
(2) "Mission to Mars"; Global Surveyor Sampler. NASA. No idea of what this disk does. $6.00 (SOLD)
(3) "Planetary Images"; NSSDC (NASA). 200+ digital images of planets, asteroids from planetary and lunar missions. $6.00 (SOLD)
(4) "Distant Suns" from Rom-Tech. I have no idea what this disk does. $6.00
(5) Mars Rover", Southern hemisphere. Again, no idea of what it does. $5.00
(6) Same as #5, Northern hemisphere. $5.00
(7) "Orbits 3.0". I looked at this one, it is neat with animations of orbits, solar interior, tides, solar eclipses, etc. Plus, all data about all solar system objects, size comparisons, density camparisons, sizes shown to scale, ephemerides and much more. Can load entire disk to hard drive (only about 4 Meg.) and save disk. VERY educational, but not too high-tech for non-astronomers on most subjects. $12.00 (SOLD)
Add $2.00 for one or two for first-class mail.
