The observation of this globular cluster is very rewarding. It finds itself
in Serpens’ constellation, approximately 25.000 light years away. M5 and M13
are the two most brilliant globular cluster in the northern hemisphere. It
has a very thick core and it can be observed how ramifications of starts
have their origin in it, the famous ‘spider legs’ that give to the cluster
its elliptical shape. The image of this beautiful cluster is completed with
the star 5 SER, with a magnitude of 5. But actually, if we observe closely
we can see that it is a double star. In this case it is the STF 1930, make
up of the star of magnitude 5 and its partner of magnitude 10, with a
separation of 11,4”.
I have done this draft in the observation area of the Astronomical
Association of Madrid (Agrupación Astronómica de Madrid) in Bonilla, Cuenca.
The weather was good and the temperature was around 3º C.
Do not miss the spectacle that this globular is offering and that will be
with us during the warm summer nights.
