Introduction to fox constellation

Fox lies south of Cygnus and north of Sagittarius and Dolphin. There is a nebula in the constellation that looks like a dumbbell, so it is called "dumbbell nebula". Among all-day planetary nebulae, Fox's dumbbell nebula is undoubtedly the most beautiful one. It ranks 27th in the messier cluster nebula list, so it is also called M27 nebula.
