M51, the Whirlpool Galaxy, was the first galaxy discovered to exhibit a spiral structure.  Material appears to be flowing from M51 to its companion galaxy, NGC 5195.  This is believed to be caused by a close or grazing collision of the two galaxies.   Amazingly this object can be imaged in light-polluted skies with a nebula filter, and this view is better than I've ever seen it through the telescope.  But it doesn't compare to other images on the web.
