Show us your astrophotography skills

As I am more and more intrigued with astrophotography, I was wondering whether some of you could share their work, and maybe explain in a short paragraph, the technique / the method / the gear they used to capture their photographs.

Photos including the Sun, stars, star trails, Moon, planets, Milky Way, nebulae & Galaxies are more than welcome.

Thanks in advance
