The H-alpha emission in this image has been enhanced by a factor 4, to highlight the star-forming regions in the disk of M51 and other HII extensions around NGC 5195. Field of view of 15 arcminutes (one quarter of the apparent width of the full Moon). North top, East left. Credits: CAHA, Descubre, DSA, OAUV.
