My photo art, astrophotography

(1/9) > >>

Vawmataw:
Astrophotography combines both photography and astronomy. It targets photographies of nebulas, star clusters, galaxies, constellations, stars, planets, etc.

To make the most perfect astrographies, you need a shutter release and a tripod.

I do active astrophotography since this January, exactly the New Year's day, and I photographied 11 pictures since this day. However, I made more before this date between 2011 and 2012. In this thread, I'll show you my astronomical art.  :D

I have these informations for you.
