Here's a new version of Reference Star Finder

http://www.astronomie-amateur.fr/Documents%20Spectro/ReferenceStarFinder.xlsm

1. Following suggestions (OHP 2015),

- the Miles data base (stars A and B) is added

- computation of altitude (the latitude and longitude of the site must be in decimal format)

2. I added a page "Trajectoire"

With the coordinates of the target, the begining time and duration for target and reference, the altitudes (and azimuth) are computed and drawn in a graph.

Of course, the coordinates of Index page must be (approximativly) the same.

By clicking on the reference list, you choose your reference star

If Alerte is on, messages will comment the reference star (difference of altitudes, interstellar extinction)

Note : correction for precession is not (yet) computed

Please, inform me for bugs
