The Pleiades

The Pleiades, also known as the Seven Sisters, or the Netted Stars, have a large presence in myth a folklore. They are also a good test of eyesight in dark skies. With good vision, you should be able to see seven stars in the cluster.

In reality, there are hundreds of stars in the cluster. On a good night, I can see nine with my naked eye. Imaging shows hot blue stars surrounded by nebulousity.

This image as taken with the Orion ED 80 piggyback on the 14 inch ACF.  The imager was the Mallincam DSm.  Even with the 80nT f/5, the cluster is so large that only a few stars show. Note the nebulousity, especially around the star at the bottom of the image (Merope).
