图示说明: 飞鱼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,飞鱼座周边的星座依次为:天舟座、天绘座、金鱼座、天案座和避役座。

飞鱼座是南天星座,因此南半球全年都能看到完整的星座形状,北半球靠近赤道的地区也能观测到。最佳观测时间是北半球冬末和南半球夏末的夜晚。

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。
