The First People looked into the night sky and saw this, the 'Unseen River', Currendelella. To the sharp eyed, the waterfalls of the Unseen River pose great dangers, just like a land based waterfall.
The First People have a story about travelling into the darkness. Some Australian trees and shrubs produce seeds with wings, including the lomatia. The lomatia's seeds, blown before a tempest, provides a path to the stars, Currendelella. When your time comes to leave for the stars, do not waste time arguing among yourself about who should lead the journey. Instead, trust in the path made by the seeds when the wind blows.
This is an (early evening southern hemisphere winter) image of the galactic core of the Milky Way, over Lake Lyall this week just before moon rise. The dark clouds, which the First People thought were cascades in the sky, are galactic dust, between us and the core. The red line you will find in the Lake is a reflection of a jet trail (look just above the horizon, inside the moon glow). You will also see slight star reflections on the lake surface (there is a dramatic fall off of reflected star light on water).
There are some similarities astronomical and waterfall photography, but the first rule in both is to try to get a good shot (and to take off all your filters for ordinary astro shots). This is a long exposure (30 seconds, so there are slight star trails and the moon glow washes out the lower sky) averaging light from the different stellar sources, slightly tone mapped to highlight subtle light differences in the dust clouds.
