Gibraltar has become increasingly light-polluted in the last few decades, with its rapidly-expanding city and nearby cities in Spain also expanding (La Linea and Algeciras). This can at times make it difficult to practice astrophotography locally. It comes down to either putting up with it or packing it all up in the car boot and driving about an hour North into Spain and getting to a darker site. There are some amazing places in Spain accessible from Gibraltar in terms of dark site but nevertheless, it involves more work than just going locally to Europa Point or up the Rock (with a Government permit for night-time access).

This has two distinct advantages, though not huge ones at that:
