Abstract
The summer season ends this month. We not only notice this from changes in nature but also from the new constellations that rise in the east. The Sun now moves towards the autumnal point in Virgo, which will be reached around September 22 or 23. Our night-time window is slowly shifting away from the galactic center towards higher galactic longitudes (see also Fig. 2.3, where the star on the ecliptic indicates the position of the Sun around the autumnal equinox). The star-filled stretches of the Milky Way still dominates the sky. The deep-sky objects on the incurving side of our own Orion Spur come within reach of our binoculars and small telescopes on September evenings (Fig. 11.1).
