L'étoile <a href="/wiki/Phi_Cassiopeiae" title="Phi Cassiopeiae">φ Cassiopeiæ</a>, située dans la même direction et près de NGC 457, forme un triangle avec les étoiles <a href="/wiki/Delta_Cassiopeiae" title="Delta Cassiopeiae">δ Cassiopeiae</a> et <a href="/wiki/Chi_Cassiopeiae" title="Chi Cassiopeiae">χ Cassiopeiæ</a> dans un chercheur 6×30 (voir l'image de DSS). Cassiopée étant une constellation <a href="/wiki/Circumpolaire" class="mw-redirect" title="Circumpolaire">circumpolaire</a>, l'amas est observable toute l'année. Mais la saison la plus propice est cependant l'automne car c'est l'époque où il culmine dans le ciel.
