Teide is a fantastic place for stargazing and astrophotography. I took this picture during the early winter season when the Milky Way core was visible for the last 10 minutes (6:26 AM). Then, I witnessed the spectacular blue hour and captured some foreground views. The foreground shot used in this picture was taken at the same place at 6:58 AM.

Sky: Single 10-minute snap at F2.8, ISO 100
Foreground: 3 different exposure frames for HDR at F8, ISO 100.
