M51 Including Supernova SN 2011dh
One of the showpieces of the spring night sky is unquestionably Messier 51 which lies near the end of the handle of the well known Big Dipper. M51 is composed of a large face-on galaxy, Ngc5194, and another galaxy, Ngc5195. The larger galaxy has wonderful spiral arms where one of these appears to stretch out to the smaller galaxy as the smaller galaxy is being absorbed by the larger one. This object is seen frequently in magazines and television programs featuring astronomy. In early June of 2011 a bright supernova designated as SN2011dh was discovered in M51. In my picture taken 1-2 days after the discovery of the supernova I have placed a label with two pointers that point to the bright supernova. This picture covers about a third of a degree with north to the left where you may be able to spot several very dim and smaller galaxies. Hint: Look all around the smaller main galaxy for fuzzy patches that are not round.
