Mill of Stars

Photographed in the evening of the 13th to the 14th of August 2013, this photo shows a startrail of 2 hours and a Perseid meteor streak(in the center) over one of the entries of a former coal mine lost in the Serra da Boa Viagem, Figueira da Foz, Portugal.
In the Northern Hemisphere, the Perseid meteor shower is one of the most famous of the year, although it can also be seen in the Southern Hemisphere, but with less intensity.
Reaching values of 100 visible meteors per hour, this year, according to the IMO (International Meteor Organization), were recorded 120 per hour at its peak that occurred during the early morning of the day 11-12 and 12-13 August, 2013. (source: http://www.imo.net/live/perseids2013/)
Every year, from around July 17 to August 24, our planet intersects with the trail of dust left by the comet 109P/Swift-Tuttle, the passage of this dust through the atmosphere burns up forming a trail light, which we call the shooting star.
The best time to observe this meteor shower is before dawn, although they may also be visible some meteors, but in smaller numbers, from the moment when night falls.
The constellation Perseus, which gives the name to this meteor shower (Perseids), is the region of the sky where you can see a greater influx of these meteors fall, at this point we call "Radiant". It is he who influence the name given to each meteor.
Technique used:
The photo itself is a combination of 240 different photos, taken during two hours, between 1am and 3am of August 14, 2013.
