Star Trails
Good image. The southern skies are much richer in detail compared to what we have up north.
Those wide white and coloured blurry bands between the tight stars are probably the Large and Small Megellanic Clouds, and maybe Eta Carinae Nebula. Have you tried a film star trails? A slower film in the 100 to 200 ISO range like Ektar 100 with good reciprocity will really bring out those colours in the nebulae. Kodak E200 or Provia 100F.
