This image shows you a comparatively larger-scaled spiral galaxy in north edge of Virgo. NGC4866 has been positioned at eastern edge of the Virgo Cluster. The galaxy has a long axis of 9 arc minutes but visual brightness is only 12th magnitude, it's not so striking one compared with plenty of member galaxies. You will be able to detect the galaxy as an only elliptic light without worthy of mention. This picture can be captured a bright central bulge, an elliptic surrounding structure, and a dimmed outer part.
