When we look at the night sky, we cannot distinguish the colour of each star. At first glance, all stars look white. However, if we register a sequence of long exposure photographs, due to the rotation of the Earth around its own axis, and consequently the rotation of the celestial sphere, it is possible to perceive how colourful the night sky is in reality.
In this image, we can see a Startrail, a product resulting from 279 images taken using a Canon 700D, Sigma Art 14mm lens, f/2.2, ISO 1600, an exposure of 25 seconds each, and edited using the StarStax and Adobe Photoshop 2020 software programs. These images were captured in the sky of Noudar Park, more specifically in Noudar Castle with little light pollution.
