As a one-off, I attempted to shoot Luminance from my light polluted home location, as it coincided with April's new Moon. 2nd night had poor transparancy.
Two extremely distant quasars are annotated in this picture. These lightsources originate from the accretion discs of supermassive black holes at the heart of young galaxies; they were emitted when the universe was only 2.8 billion years old. These lightbeacons took over 11 billion years (!) to reach earth.
