    Re: Digital Camera Celestial Navigation

    Greg,
    
    It's now over a year that I started to use this celestial navigation
    procedure for measuring the refraction near the horizon from sunset
    events. All these photos, I guess there are now probably around 800,
    have been recorded with the corresponding atmospheric conditions. The
    data still wait to be entered in a database for further analysis. This
    database still has to be set up. It's intended to make it publicly
    available via Internet in order that all those interested in it could
    also add their own observations.
    
    Anyone interested in this project is welcome.
    
    Marcel
