Praesepe, also known as M44 or the Beehive cluster is one of the brightest open clusters in northern sky. Visible with unaided eye, even in urban areas. I have applied some filters to enhance the picture, including an artificial diffraction mask to get spikes. Using the shift-and-add technique for 1 minute I got this result.
