M45, The Pleiades with Diffraction Spikes


Click image for larger version.


Playing around with an artificial spider I made to create diffraction spikes on brighter stars as a warm up for the main event of the evening which was the Horsehead Nebula.  The spider obviously works well.  I like diffraction spikes especially on wide field constellation shots where the spikes really point out the main stars of the constellation among the swarms.
