Steve, I think you may be thinking of "Mars Previewer II", it can be downloaded from S&T website at http://www.skyandtelescope.com/resources/software/3304921.html?c=y&page=2 Clear Skies, Keith Schlottman -----Original Message----- From: az-observing-bounce@xxxxxxxxxxxxx [mailto:az-observing-bounce@xxxxxxxxxxxxx] On Behalf Of stevecoe@xxxxxxxxxxxxxxxx Sent: Monday, January 04, 2010 12:49 PM To: az-observing@fre Subject: [AZ-Observing] Mars viewing software Howdy all; I know that there exists a freeware program that will show you which side of Mars is facing you at a given time and date. I think it was called something like "Mars Preview". I know I had it, but it is now gone. Sky and Tell has a similar program on their website, but I want one I can have on my hard drive. Can someone here point me to this program on the Web?
