You can use my program, it also predicts iridium flares, transit of any object(Sun, Moon, all planets, RA Dec position, Star), has sky mode or view from space and a bunch of other stuff. It has auto-download from Space-Track. It is free and works on win98se, Me, 2000, xp. http://www3.telus.net/public/boucherd/main.htm Denis Rainer Kresken wrote: > Gerhard, > > and how do I know what the course of the groundpath is and when a transit > occurs close to my home? > > Rainer > > >>I've used a 3 inch Apo-refractor with an ND5 glass sun filter, just what I >>normally use for sun observations.
