Diagram caption: 天狐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,天狐座周邊的星座依次為:天鵝座、天琴座、 武仙座、天箭座、海豚座和天馬座。

天狐座是北天星座,因此北半球全年都能看到完整星座,南半球赤道和溫帶地區也可見。最佳觀測時間是北半球初秋和南半球初春的夜晚。行星狀星雲M27(天鈴星雲)位於天狐座內,圖中以綠色十字疊加符號標注。疏散星團NGC 6885同樣位於天狐座,圖中以黃色圓圈標注。

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。
