How to Find It

Locate the Pleiades cluster in the constellation Taurus by looking near the V-shaped Hyades cluster; Merope is the southernmost bright star in the central dipper-shaped asterism of the group.

Observing Tip

To detect the subtle nebulosity surrounding the star, use a low-magnification eyepiece under a dark sky and employ the averted vision technique to maximize retinal sensitivity to faint light.
