Messier 5 is a globular cluster located in constellation Serpens. I revisited this cluster after four years. Such 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 different coma corrector and the camera. Moreover, this time I dedicated significantly more integration time, specifically I collected 2.7 hours the photons traveling to us 24 500 years.
