After a whole year of work (really hard this one), now is time to rest and relax.
So, yesterday I went with some friends to Serra do Alvão, Vila Real (Portugal), and we started to watch the night sky and some astronomical objects with telescopes.
I don't have a telescope. So, I took some pictures and, for the first time, I captured Andromeda's Galaxy.
The result is three pictures combined as one.
Have a nice summer time.
