In the fall, there are a number of exciting open star clusters to see in the sky, with many of them directly overhead, making for easy viewing from a number of locations. Open star clusters are much less dense than their globular counterparts and a pair of binoculars with a lower magnification allows for a more comprehensive view. Perhaps the most famous star cluster in the night sky, the Pleiades, will glitter in the night sky with 'the follower' Aldebaran not far behind it, with the Hyades cluster in Taurus. The Alpha Persei cluster in Perseus is high in the sky too, with the brightest member Mirfak shining amongst the rest. The Celestron Trailseeker 8x42 binoculars will not only get you great views of star clusters but they will give you a stunning view of the full Harvest moon on Oct. 6. See if you can spot any lunar seas or craters!
