Hi: One way to determine star to star angles is with either Starry Night Pro or TheSky. Both of these astronomy programs move the star locations from the almanac date forward to account for earth precession and for proper motion of the stars. Atmospheric refraction is also included so the elevation of the observation is needed. A friend who uses Starry Night Pro got these separations on 29 Sep 2004: Vega sep to Altair reports 34d 11'42" The Vega -Eltanin sep reports as 14d 31'46" Have Fun, Brooke Clarke, N6GCE -- w/Java http://www.PRC68.com w/o Java http://www.pacificsites.com/~brooke/PRC68COM.shtml http://www.precisionclock.com
