M94 (NGC4736) is a colorful magnitude 8.99 spiral galaxy in the constellation Canes Venatici. What makes this galaxy interesting, is the presence of 2 ring structures. The inner ring appears to be an active star-forming region, while the outer may be an accretion disk. It was discovered in 1781 by Pierre Méchain and cataloged by Charles Messier only 2 days later.
