Thursday September 23 to Thursday September 30
The Last Quarter Moon is Wednesday, September 29. Four bright planets are seen in the early evening sky. Venus and Mercury are readily visible in the evening sky. Mercury, the bright star Spica and Venus from a line in the late evening twilight. Venus is close to the bright double star α2 Librae (Zubenelgenubi) on the 24th. Saturn and Jupiter are visible in the evening sky with Jupiter dominating once Venus has set.

The inset shows the telescopic view of Venus and Mercury at this time, and a binocular view of Venus and α2 Librae. Similar views will be seen throughout Australia at the equivalent local time (90 minutes after sunset, click to embiggen).

Mercury is now high in the twilight. Spica, Mercury and Venus make a line in the late evening twilight with mercury just above Spica.
Venus is visible in the early evening when the sky is fully dark. I have been able to see Venus from just after sunset and it is easily seen over 2 hours after sunset, longer if you have a clear western horizon. When the sky is fully dark you can see Venus above the western horizon and bright Jupiter above the eastern horizon. Venus is close to the bright double star α2 Librae (Zubenelgenubi) on the 24th. Venus and the paired stars are easily visible in binoculars together.
Jupiter is now rising before sunset and is readily visible when the sky is fully dark. Saturn and Jupiter form a line in the sky. Jupiter was at Opposition, when it was biggest and brightest as seen from Earth on August the 19th, and is still excellent in even small telescopes.
