View of the Carina Nebula taken from the Astronomy Observatory of Los Molinos (OALM) (es) located in Montevideo, Uruguay. The picture is based on 9 frames of 2 minutes exposure time each with a Nikon Df and a catadioptric Nikkor 500mm f/8 lense, apart from the dark, bias and flat frames for the post-processing. For the post-processing a dedicated software for this kind of photography (PixInsight) was used that merges the images, analyses the brightness scale, reduces the noise and enables the management of saturation and dynamic range.
