Re: Neede recomendation for D7000 lens..
In my opinion it's not all about the gear / lens. It comes down to aperture and exposure time. A few years back I was taking lightning photos and night shots with a Kodak EZ share, yeah my Nikon does produce a better quality night shot, but I still had keeper photos with a point and shoot camera.
Best advice I can give is going out and play with your camera and your settings at night. I live out in the country so it's not uncommon for me to use a lower f/stop of 5.6 or under, but if I'm shooting in the city I might be shooting at f/22. It all depends on how much or how little light you have to work with.
If you're trying to photograph the moon, treat it as a daylight shot and not a night shot. How soon we forget the moon is being lit up by the sun, even though our surroundings are dark.
If your night photos have a red cast to them, then you're over exposed at the aperture setting. Use a smaller aperture or use less of an exposure time.
That's my 2-cents worth.
