M45, The Pleiades, or The Seven Sisters, are an open star cluster located in the constellation of Taurus. It is among the nearest star clusters to Earth and is the cluster most obvious to the naked eye in the night sky. Dust that forms a faint reflection nebulosity around the brightest stars was thought at first to be left over from the formation of the cluster, but is now known to be an unrelated dust cloud in the interstellar medium, through which the starlight is passing. This image was captured using amateur astrophotography equipment including a Skywatcher 80mm telescope, a QHY269M monochrome camera and a seven position filter wheel containging Red, Green, Blue, Hydrogen Alpha, Oxygen III and Suplphur II filters. Tracking was done using an iOptron CEM70G mount and PHD2 guiding software. It was entirely processed using PixInsight. Science | Horizontal | USA | Sky | Outer Space
