Hi Coen,
have a look at the thread I started on Eta Carina the other day. RobH has included an amazing link detailing landmarks of this amazing nebula, including the Homunculus. Have a look at the link he provided. I've since added my observations of the nebula and the Homunculus.

Requirement wise to see the Homunculus, anything over 100X will show it clearly. I saw it, no problem at 133X. It is a little smaller than Saturn through a scope, and it is a bright orange in colour. A nebula filter will actually cut its light out. Even thought the moon is out this evening, the Homunculus is bright enough to see it clearly despite the Moon glow.
Mental.
