Despite the fact that it’s autumn, it is still possible to observer many of the summer constellations still visible in the west. Although Hercules is often regarded as a summer constellation it won’t be setting until after midnight and is therefore well placed for observing in the early evening sky.

 

Even under moderately light polluted skies the ‘keystone’ of Hercules is easy to find below Vega and once it is identified you can use it to locate two variable stars suitable for binoculars: G Herculis and UW Herculis.
