The light you see in the photos attached has been sent 720'000'000 years ago, long before the Cambrian geological period of our planet.
Both photos above have been taken using an amateur telescope and color camera. The exposure time was 13 times x 15 minutes under the light polluted suburban sky. Special photo-processing techniques have been applied on the raw images in order to remove the disgusting dirt of the city lights (see description).
Finally, I have to state how disappointing is to realize that the darkness of our night sky is still not protected by law in most countries on the globe.
