A few weeks ago I took a night trip to Jenolan Caves, specifically to shoot a few shots for their inaugural photographic competition.
Attached are a few of the shots that I took.
Unfortunately the Milky Way was too low and flat on the horizon to make any feature in the shots, and there was a moon hovering around there somewhere, so it was a little sparse for stars unfortunately.
They are my usual formula.
Canon EOS 7D
Tokina 11mm-16mm @11mm
ISO 1600-3200
20 seconds at f2.8
Some vertical panos, some horizontal panos, all single row however.
