Diagram caption:
飛魚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,飛魚座周邊的星座依次為:天舟座、天繪座、金魚座、天案座和避役座。
飛魚座是南天星座,因此南半球全年都能看到完整的星座形狀,北半球靠近赤道的地區也能觀測到。最佳觀測時間是北半球冬末和南半球夏末的夜晚。
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。
