It's getting harder and harder to find dark spots in Spain, the light pollution it's getting worse over the years.
This is maybe the darkest place in Spain, with 21,6-7 skies (classic SQM). High altitude of above 1700 meters and no light domes above 10-15º.
M31 is no longer a fuzzy patch, it's clearly a galaxy with nucleus and it's BIG. The milky way extends well into Ophiuchus, and it's extremely complex. The effect is that the sky itself it's glowing, it's clearly bright, without any artificial light shining distracting that view.
The seeing is mind blowing, unless the wind is coming from the South, which is hot and turbulent, and destroys transparency.
We stayed three nights, two of them were 21,4-5 SQM with excellent seeing, and one of them with 21,6-7 and average to good seeing (the weather was changing).
