Nothing amazes even the most inveterate skywatcher more than traveling to another hemisphere and seeing sky move. It moves the wrong way!
Whether you are from the southern hemisphere traveling north, or as I do, travel south from the Northern Hemisphere, watching how the sky moves can be disorienting.
Here I present a video montage of time-lapses shot last April in Australia, at the annual OzSky Star Party near Coonabarabran in New South Wales.
Select HD and Enlarge button to view at full screen at best quality.
You’ll see the sky set in the west but traveling in arcs from right to left, then in the next clip, rise in the east, again moving from right to left. That’s the wrong angle for us northerners.
Looking north you see the seasonal constellations, the ones that rise and set over a night and that change with the seasons. In this case, the night starts with Orion (upside-down!) to the north but setting over in the west, followed by Leo and bright Jupiter. The sky is moving from east to west, but that’s from right to left here. The austral Sun does the same thing by day.
Looking south, we see the circumpolar constellations, the ones that circle the South Celestial Pole. Only there’s no bright “South Star” to mark the pole.
The sky, including the two Magellanic Clouds (satellite galaxies to the Milky Way) and the spectacular Milky Way itself, turns around the blank pole, moving clockwise – the opposite direction to what we see up north.
I shot the sequences over four nights in early April, as several dozen stargazers from around the world revelled under the southern stars, using an array of impressive telescopes supplied by the Three Rivers Foundation, Australia, for us to explore the southern sky.
I’ll be back next year!

Absolutely not. Thank you for asking.

Truly amazing.

Very good such a different view from the southern hemisphere compared to us on the 49th parallel with light polluted skies. Good choice of music too.
