Observation

The image was obtained with a usual mechanical camera and lens of normal focal length (50mm). Guiding was done on a Super Polaris mount. The place is in the Hakos mountains of Namibia, southern Africa.

Processing

The conventional photography was digitized to about 12 megapixels and a color depth of 3 x 12 Bits. Digital image processing improved the quality of the image dramatically. The main steps are the subtraction of the terrestrial skybackground and following contrast enhancement.
