Diagram caption:
天狐座及其明亮恒星与周边星座示意图。从顶部开始沿顺时针方向,天狐座周边的星座依次为:天鹅座、天琴座、 武仙座、天箭座、海豚座和天马座。
天狐座是北天星座,因此北半球全年都能看到完整星座,南半球赤道和温带地区也可见。最佳观测时间是北半球初秋和南半球初春的夜晚。行星状星云M27(天铃星云)位于天狐座内,图中以绿色十字叠加符号标注。疏散星团NGC 6885同样位于天狐座,图中以黄色圆圈标注。
该图的纵轴为赤纬,横轴为赤经,方向为上北下南左东右西。图中标注的恒星大小对应其视星等——衡量天体视亮度的标准,较大的圆点代表着较亮的恒星。图中的希腊字母标注着星座中最亮的恒星。这些恒星按亮度排序,最亮的一般被标记为α星,第二亮的一般为β星,等等,不过这种字母排序并不总是和实际亮度排序完全一致。图中虚线标注的是国际天文学联合会划定的星座边界,绿色实线则是一种常见的星座形象连线。需要注意的是,在实际观测时,这些边界与连线都不会出现在天空中。
