Some of the northern and eastern sky is blocked off by a nearby bluff, but, in a kind of exchange, the whole southern horizon is wide open, offering people a view of targets rarely seen from Orange County. Polaris should be visible, although it is fairly close; the northern horizon is at an elevation of about 29 degrees.
