The sky map shows the entire sky as viewed from a given location at a specified time and date. A stereographic projection
is used, as is the convention for printed star maps.
To make a sky map, enter the latitude and longitude of your observing site in the boxes below (be sure to check
the correct "North/South" and "East/West" settings) and press the "Make Sky Map" button below the form. Your Sky
will deliver a map showing the sky above the location you specified at the current time. On that reply page you can enter
different dates and times, observing locations, display options, and orbital elements of asteroids and comets you wish to
track. If you don't know your latitude and longitude, you can specify them by selecting a nearby city.
Horizon Views, showing the stars above the horizon as seen from a specified observing site at a given date and time. The
viewing direction (azimuth) may be set to cardinal points on the compass or arbitrarily by entering a value in degrees.
To make a horixon view, enter the latitude and longitude of your observing site in the boxes below (be sure
to check the correct "North/South" and "East/West" settings), select the direction in which you wish to view the horizon,
then press the "Make Horizon View" button below the form. Your Sky will deliver a map showing the view toward the
horizon in the given direction at the present time. On that reply page you can enter different dates and times, observing
locations, viewing directions, display options, and orbital elements of asteroids and comets you wish to track. If you don't
know your latitude and longitude, you can specify them by selecting a nearby city, then navigate to the Horizon View from the resulting Sky Map page.
Your Sky's Virtual Telescope is your Humble Soft Telescope of the Web. Controls allow you to set time and date, aiming point, orbital elements to track an asteroid or comet, and a variety of viewing options.
You can compose a request with custom settings and save the results in your browser's hotlist or bookmark table, allowing direct access to the virtual telescope with all
the controls preset to your own preferences.
To launch the virtual telescope, enter the coordinates at which it should be aimed in the boxes below and push
the "Aim Virtual Telescope" button. You also aim the virtual telescope at objects in the sky chosen from a variety of object catalogues.
