Thanks, Tom for pointing this out. After reading your email I downloaded
Mars Previewer II and went to see if I could see Olympus Mons and other
features in the relatively humble photos I took of Mars Sunday morning. I
had a good time and look forward to trying this out through the eyepiece
Saturday night.
