Messier 5 is a globular cluster located in the constellation Serpens. I revisited this cluster after four years. Such a spectacular deep space object simply deserves more attention, than I was able to spend four years ago. At that time I used the same telescope, but now I have a different coma corrector and camera. Moreover, this time I dedicated significantly longer integration time, specifically I was collecting the photons 2.7 hours, which were traveling to us 24 500 years.
