La Palma, Canaries, Spain

In the middle of September a group of five amateur astronomers went on an 10 day trip to La Palma island in Spain. The first week was devoted to observing the night sky on the top of the caldera and sightseeing around the island. Last four days we attended the 31st International Meteor Conference. Here are some pictures of the massive telescopes and sights we were able to admire on the island.

One of the twin Magic gama-ray telescopes with a diameter of 17 meters.

Every night we observed the sky at the top of the caldera near the Roque de Los Muchachos observatory.

Zodiacal light and bright planet Venus.

Summer time Milky Way towards the Constellation Sagittarius, including the Galactic Center.

As you can see from the pictures bellow even the sites with best atmospheric conditions are not free of the light pollution. Professional astronomers should take the matter into their hands if they hope to continue with the observations in the coming decades.
