M61 is a bright, face-on spiral galaxy that is a member of the Virgo cluster. It is easily visible in the telescope it appears as a bright eliptical haze with a bright nucleus. Even though M61 is situated about 10 degrees from the centre of the Virgo cluster, the region is still rich in faint galaxies. There are more than 20 in the photograph below.
