When the Sun shrinks to a dull red dwarf, it will not be dying. It will just be starting to live and everything that has gone before will merely be a prelude to its real history.

Description:

This tinny little object is also known as the Rocking Horse cluster. The name says it all: it really looks like a little horse jumping around the space. Although it's in a quite easy position, it still is a neglected object, as when it comes to Cygnus, everyone thinks of nebulae like the Veil and its companions, and the tiny shiny planetaries. Too bad, because this cluster is a real gem! It's special features are the two brightest stars of the cluster (at the front leg and the eye), that are apparently yellow, even though their spectral class suggests a rather white colour. This optical illusion is caused by the interstellar dust that is so common through Cygnus. A very important hint: you should use a fairly high magnification when looking at this object, because it's located in a field that is rich in bright stars, which makes it harder to detect the real shape of the cluster.
