Diagram caption: 唧筒座星图

唧筒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,唧筒周边的星座依次为:长蛇座(Hydra)、罗盘座(Pyxis)、船帆座(Vela)与半人马座(Centaurus)。作为南天星座,唧筒座全年可在南半球全境观测,北半球赤道带及部分温带地区亦可见其踪迹,最佳观测时段为北半球春季与南半球秋季的夜晚。

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。
