Hi John You write that the chart must be in Alt-Az to be able to show the local horizon. I now tried to alter the Alt-numbers in the horizon_Geneve-file and saved it under another file-name...so the Geneve-file isn't overwritten. But for some reason, neither my own trial-horizon nor the Geneve-horizon is displayed on the chart. Also, I can only display the Equatorial grid but not the Azimutal one, although both are activated under "lines".
About my trial-horizon-file: starting Azimut is 0, ending one 359. Thanks Luzius --- In [email protected], John Mahony <jmmah...@...> wrote: > > That looks like the same format as for v2.76.
