====== Observatory Setting ======
The Observatory setting has two tabs:
  * [[observatory#observatory|Observatory]]
  * [[observatory#horizon|Horizon]]




===== Observatory =====

Define the location of the observation site to be used when calculating the altitude and the azimuth position of objects in the chart. At a first approximation you can also use the list of the major world cities.

Enter the latitude, the longitude, the altitude (in metres) and the time zone of your observatory. Enter also the pressure (in millibar) and the temperature (in Celsius degree) to be use to calculate the atmospheric refraction.

You can assign a name to a location. Press "Update" to keep it for next session. It will appear in the list of the available locations.

If you don't know your observatory coordinates click "Map" and select your location on the map using the mouse. It is possible to zoom or to replace this map by another of your choice, the only restriction is it must use the same projection.

It is important to select correctly the observatory time zone in order to calculate the difference with UT and ''Daylight Saving'' setting. This is basic for correct chart and ephemeris calculation.
