Object Info:

M45 or the Pleaides. This big naked eye cluster lies in the constellation of Taurus. Its diameter is 2 degrees. Under my suburban skies I can detect only 6 stars with the naked eye. With 15x80 Vixen big binoculars I can detect about 60 to 70 stars. This is truly a binocular cluster! Many chains of stars are visible. There are also some beautiful double and multiple stars to be observed. The most striking is Alcyone, the bright A component accompanied by three fainter companions. I could not detect any nebulosity. The sketch to the left is not complete. I will try to enhance it (plot more stars) in a next session.
