唧筒座星圖
唧筒座及其明亮恆星與周邊星座示意圖。從頂部開始沿順時針方向，唧筒周邊的星座依次為：長蛇座（Hydra）、羅盤座（Pyxis）、船帆座（Vela）與半人馬座（Centaurus）。作為南天星座，唧筒座全年可在南半球全境觀測，北半球赤道帶及部分溫帶地區亦可見其蹤跡，最佳觀測時段為北半球春季與南半球秋季的夜晚。
該圖的縱軸為赤緯，橫軸為赤經，方向為上北下南左東右西。圖中標注的恆星大小對應其視星等——衡量天體視亮度的標準，較大的圓點代表著較亮的恆星。圖中的希臘字母標注著星座中最亮的恆星。這些恆星按亮度排序，最亮的一般被標記為α星，第二亮的一般為β星，等等，不過這種字母排序並不總是和實際亮度排序完全一致。圖中虛線標注的是國際天文學聯合會劃定的星座邊界，綠色實線則是一種常見的星座形象連線。需要注意的是，在實際觀測時，這些邊界與連線都不會出現在天空中。
