Also the other way around. >> Hi all, I use both programs and they are quite different. I use Chris' Skymap since 1994 for what it is, a Windows planetarium. I have an old version but the last one have 259000 stars and 10000 deep sky objects. You can add comets elements, you have an eyepiece database to show you the real size of the sky seen inside you eyepiece, toolbars to add or hide objects, to change time and many more features you will find at Chris Mariott's web site: http://www.skymap.com The new versions can make satellite prediction pass but I do not use it for that. I also us Dance of the Planets as planetarium program. I use Rob's SkyMap only for a few months. I do my nightly satellite predictions with it together with some of Alphonse Pouplier's programs. I think both programs are very valuable. ------------- Message to Rob: I have no easy way of sending a small amount of money to you from New Caledonia but I will find another way to thank you for your sofware. :-) ------------- Jean-Christophe 'Papou' Millot - email : papou@canl.nc Consultant en Technologies de l'Information - IT Consultant B.P. 13581 98803 Noumea CEDEX Nouvelle-Caledonie - New Caledonia (22d17S, 166d28E) UT+11 Tel/Fax/Rep : (687) 27 69 84 - Mobile : (687) 77 19 97
