Full Moon

I have been trying for a long time to get a decent photo of the Moon with detail. I think this one is ok, but I realize I am limited by my knowledge and possibly my equipment. I use a Nikon D40. Although I am pleased with my Camera, I would love to update to a Nikon D90. Any thoughts or suggestions is greatly appreciated! I love this site and all the wonderful photos of places I could only dream of visiting. Thank you all for sharing your lives and locations!
