Diagram caption:
網罟座及其亮星與周圍星座。網罟座被以下星座環繞（按順時針方向）：時鐘座、水蛇座和劍魚座。網罟座是一個南天星座，因此在南半球的某個時段可以看到整個星座。在北半球赤道的大部分區域也能完整觀測到該星座，而在赤道地區的其他區域以及北半球部分溫帶地區則可以觀測到該星座的部分。對於整個南極地區和南半球的大部分溫帶地區而言，網罟座是環繞極地的星座。該星座在北半球的冬季和南半球的夏季晚上觀測最佳。
本圖以北為上，以度為單位的赤緯表示縱軸；以東為左，以時為單位的赤經表示橫軸。圖中標注的恆星的大小與恆星的視星等有關，視星等是衡量恆星視亮度的標準，較大的點表示較亮的恆星。希臘字母標記了星座中最亮的恆星，通常按亮度排序，最亮的恆星標記為α，次亮者標記為β，以此類推，不過這種排序並不總是有效的。虛線標示出國際天文學聯合會規定的星座邊界，而綠色實線則表示常見的星座連線方式。然而，星座的邊界線以及恆星之間的連線並不會出現在實際夜空中。
