Lenses for sony nex c3 help

[Mrlozza]

Hello all, Im looking to buy a new lens for my Sony nex c3. I have the bog standard 18-55mm len at the moment, i'd like a powerful len to be able to capture a new photo of the moon (nice close up) i know that sony do an E 18-200mm and a 55-210mm think both are telephoto. I know I can get an E to A mount but if I have to I'll do that. Can someone point me in the right direction for the right lens pleaseKind regardsLozza
