   On the morning of Monday 21 July look toward the southeastern horizon for the waning crescent Moon to be about 6-7o away from the open star cluster known as the Pleiades, or the 7 Sisters. There are a variety of mythologies about these stars and why they are called the Seven Sisters even though most people only see 6 stars. Which too many folks looks like a small dipper shape. In darker skies it is possible to see up to 12 stars.
21july-bino   The Pleiades, or M-45, is an open cluster containing around 500 stars. In many time exposure pictures bluish-white nebulosity seems to surround the stars. The nebula is actually a Reflection Nebula, glowing from the light of the stars within the cluster. The Pleiades are easy to see with the unaided eye and become more spectacular when an optical aid is used.

Caution: Objects viewed with an optical aid are further than they appear.
