Altair starfield, adjusted and optimised image
20 sec exposure with Astrotrac tracking arm. The original single shot was cropped and adjusted to show dim stars and enhance black sky, by maximising contrast, brightness, sharpness and exposure with just Apple Photo software. See the original shot as the following image in this album. I was amazed how clarity and detail could be obtained from a simple single exposure with no stacking or other sophisticated image manipulation. All the visible light points are real as they appear in other frames taken at different times as they appear in same relative positions but in different parts of the detector due to starfield rotation.
