Open Cluster in Andromeda
Located below the cornucopia shape of Andromeda, this is a large open cluster of some 70 or 80 stars. It can be glimpsed with the naked eye as a hazy patch under very dark skies, but it is much easier target with binoculars. In fact, the best views of this cluster are either with a good pair of binouclars or a telescope with a very field of view, since the stars span an area of sky almost 1 degree in diameter.
