Visibility
With a declination of 56° 32' North, Schedar is principally visible in the northern hemisphere. The star is yet discernible to most observers across the globe reaching as far south as Perth, Australia, Santiago, Chile and other settlements north ± 33° South latitude, albeit just above the horizon. Schedar is located in line-of-sight of the Milky Way galaxy, so there are other notable celestial objects one can view close to this star—the Pacman Nebula, NGC 436 and NGC 457 being a few.
Alpha Cas reaches its zenith above cities like Edinburgh, Copenhagen and Moscow. It is circumpolar throughout Europe, Russia, and as far south as Los Angeles, California on the North American continent as well as other locations around the globe having a latitude greater than ± 33° North. Since Schedar is listed as a second magnitude star, it is easily observable to the naked eye as long as one's stargazing is not hindered by the light pollution common to most cities.
The best time for your observation is during the late autumn months of the northern hemisphere, when Cassiopeia passes the meridian at midnight, but given its circumpolar nature in many northern localities, it is visible to many of the world's inhabitants throughout the year.

Famous quotes containing the word visibility:
“My children have taught me things. Things I thought I knew. The most profound wisdom they have given me is a respect for human vulnerability. I have known that people are resilient, but I didn’t appreciate how fragile they are. Until children learn to hide their feelings, you read them in their faces, gestures, and postures. The sheer visibility of shyness, pain, and rejection let me recognize and remember them.”
—Shirley Nelson Garner (20th century)
