Barragem de Santa Clara - 100 frames taken 18-08-2012 00:36 to 01:26 (30s,
f3.5, ISO 500, WB cloudy) orientation to the North (Polaris at the center)
During those 50 minutes I noticed two events, both in individual frames:
Event 1 probably a shooting star. Event 2 shooting star aligned with the camera axis or ???
