Astrophotography
A visual temporal journey
Look to the sky by a clear night and see how was the universe thousands years ago. Because of the astronomical distances between certain objects of the celestial vault and us we can only be satisfied with the image which these object had.
(The Orion Nebula photograph nowadays, but as she was 1344 years ago.)
Make a (double) wish !
If you're lucky during your observation of the night sky, you will have the chance to observe the brief apearence of bright travelers. Impossible to anticipate, you can barely see them and they have already disappeared. You see them, this moment is yours, make a wish !
Above Light Pollution
Astrophotography is the art to capture light from billion kilometers away but it's also your worst enemy at few hundreads of meters. You've got to runaway from light to be able to capture a few shy ray of deepsky light.
