In this paper we are concerned with the image of the normal Gauss map of a minimal surface immersed in ℝ3 with finite total curvature. We give a different proof of the following theorem of R. Osserman:The normal Gauss map of a minimal surface immersed inℝ3 with finite total curvature, which is not a plane, omits at most three points of𝕊2
Moreover, under an additional hypothesis on the type of ends, we prove that this number is exactly 2.
