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.
