    Right now, I am developing a project relating to the sky. The idea is to pick
    the right sky image above the different city, for example, I want to capture
    the sky image above Beijing at 12pm, July 1, 2012, also, the image with the
    local time 12pm above Amsterdam, Washington, Mexico, Cape Town, Melbourne,
    etc. I have downloaded the Stellarium software, but when I change city at the
    Location Window, it's not working. Could you please give me some advice how to
    do it? thanks.

    Stellarium gets its date, time and time offset from the computer clock by
    default.

    If you change the location using the map or the city list in the location menu
    you will see the sky at the new location at your current computer time with
    time zone offsets etc.

    To see the new location at a particular time you can either set your computer
    clock to that locations local time or you can use the time setting menu in the
    configuration menu under navigation.

    Hey Barry,

    Thanks for your answers. That's a great software, but I still have one more
    question regarding to the time, could you please explain me a bit how it is
    possible that I can check the sky map in 2013? because it's difficult for me
    to predict as an artist:) Is it manipulated and calculated in the computer, or
    it will be the same as the result from Stellarium?

    Thanks for your kind help and look forward ...

    You can set the date to any time between about -4000 and + 4000 with quite
    good accuracy. Outside this range the accuracy drops off.

    Stellarium uses the standard algorithms that explain the movement of the stars
    and solar system that are used everywhere in astronomical calculations so If
    you select a date in 2013 at a particular time and location the view should be
    very accurate.

    The computer uses these algorithms to do all its calculations.

    You can add any new locations that you like.
    Open the location menu and enter the name as a new location. In the windows
    enter the latitude, longitude, Altitude, country and planet and save it. (Add
    to List)
    The details will be added to a file "user_locations.txt " in you user area
    under data.
    This file will be read at start up and the location will appear in the
    location menu next time.

    Barry
