Messier 5 is a globular cluster in the constellation Serpens distant from Earth 25000 light years.
This is the processed image from the sequence of images shot by Susy Ghia using the 150mm f/5.35 refractor, part of the network of ASTRA remote telescope in Castiglione del Lago, Italy.
I combined six images for a total of 6 minutes in Luminance, then I used two images, R and B channel from the DSS2 survey in order to add colors to the photo.
