Very nice and many thanks for sharing. Being there was fantastic. I remember last year in June that a Spanish photographer ask us the permission to take a time...
Stunning! It does seem that clouds do not make a very good light pollution filter though :-( Are there any light pollution laws on Tenerife? Cheers Robin ... ...
So far as I understood from the Sky Law, Tenerife must obey the law regarding the protection of La Palma's sky. That is, external lights from the side oriented...
