This is probably one of my favourite startrail images. It was taken near Polentswa in the 'Smack Bang' middle of the Nossob River facing approximately South-West.
Its made up of several exposures over approximately 1 hour.
I chose this composition to personify the Huge Night Sky's experienced in the Kgalagadi leaving only just enough frame for foreground in this image; giving the sensation of standing in the Riverbed and Looking up into the sky.
To hear the full story behind this image; you will have to join me next to the campfire for a couple of beers at some stage of you adventures
