Absorption or dark nebulae are massive clouds of dust and gas floating in the interstellar medium, which obscure the light from background stars.
Within the denser regions of these clouds the gasses accumulate over time and eventually collapse due to gravity, setting off an atomic fusion chain reaction giving birth to new stars.
At the right of center, within the cloud, lie the bright blue reflection nebulae NGC 6727 and IC 4812, and the globular cluster NGC 6723, a swarm of hundreds of thousands of stars.
This shot of the molecular cloud of Corona Australis is the result of over 16 hours of exposure time shot throughout 3 separate nights with my telescope.
