NGC4361 is a compact planetary nebula positioned in the square of Corvus in spring's southern skies. The nebula has a brightness and size of 10th magnitude and only 1.8 arc minutes, respectively. Maybe you can distinguish the nebula from normal stars by using of magnifying power over 100, and the nebula has a bit bluish color. The picture tells you the nebula has a fairly warped shape, not simple oval appearance. The nebula was formed by gaseous matter gushed out from a dead dwarf star.
