Hi Ingrid. I think you may need to stretch your data in a program like photoshop. Unlike daytime photos, astrophotograpy often need some software processing to get the data hidden in the image. Not sure what camera, lense and f:stop you are using. I tend to use aroun f5. I often image at Gawler as I am one of those Guys you see flying overhead at Gawler. I use the Gawler Airfield as I have a clear view and its nice an dark.
