Análisis de 9 filtros antipolución lumínica: “una oferta informativa que no podrá rechazar ningún fotógrafo nocturno ni astronómico”.

– las criaturas torturadas –

Os confieso humildemente que no se que es un “Light Pollution Filters”, así que me ha parecido lo más razonable empezar con este párrafo en las dos versiones habituales.

Light-Pollution Sources

Light pollution comes from any artificial light, be it on a suburban porch or a city street lamp. If you think your town has a lot of street lights, New York City operates more than 250,000 of the dark-sky fighters—many unshielded. At 305 square miles, that is more than 820 street lamps per square mile. No wonder it is “The City that Never Sleeps.”

Fuentes de contaminación lumínica

La contaminación lumínica proviene de cualquier luz artificial, ya sea en un porche suburbano o en una farola de una ciudad. Si crees que tu ciudad tiene muchas luces de la calle, la ciudad de Nueva York opera más de 250,000 de los luchadores del cielo oscuro, muchos de ellos sin blindaje. A 305 millas cuadradas, eso es más de 820 farolas por milla cuadrada. No es de extrañar que sea “La ciudad que nunca duerme”.

Sentado ya este principio básico ya estoy en condiciones de contaros que los aguerridos chicos de la tienda más grande del mundo en sus horas libres y no remuneradas han pasado revista a 9 de estos filtros antipolución de 9 fabricantes distintos y en las tres partes que componen su análisis os hartaréis de ver videos y leer sesudos comentarios sobre la cuestión.

Tal como puse en el título es “una oferta informativa que no podrá rechazar ningún fotógrafo nocturno ni astronómico”.

Estas son las redondas criaturas que han sido sometidas a tortura.

Y estas son las tres partes del análisis completo de B&H. Hala, que lo disfrutéis.
