Each map provides the list of the best objects you can see tonight, with the naked eye or binoculars. First select your location on Earth, wether you are in the northern or southern hemisphere, or near the equator. Then choose the approximate hour you plan to observe the stars. The sky slowly changes along the night as the Earth rotates.

Finally select the kind of map you need. Full color maps are intended for laptops or handheld devices. Choose the black and white version for printing. Some users will prefer a map will red colors, that to preserve their eyes sensitivity.

How to use the map

The map shows what you see looking at the zenith. The apparent inversion of East and West compared to road maps is therefore normal. As a starting point, face the North, and hold the map in you eyesight direction, with its North down. As you change the direction, rotate the map accordingly.

The objects listed on the first page can be observed with naked eyes, in a clear sky with moderate light pollution. Close your eyes one minute and let them adapt to darkness. You will be surprised how many more details will be apparent.
