Nikon Canon D80 Lens for night?

Hi i'm looking for any good suggestions for a camera lens i want to take pictures at night and of the stars.

Any will do, as for that purpose a tripod will be pretty much mandatory anyway - even the fastest prime lens won't be fast enough for shooting a dark night sky handheld.

So… Just get a tripod and stick to your current lens, whatever it may be. If you want a ultra wide angle lens for panoramic night sky shots, consider the Nikkor 10-24mm, Tokina 11-16mm or Sigma 10-20mm (the f/4-5.6 version of the sigma lens is both cheaper and sharper than the f/3.5 version)

You can use any lens. You'll be shooting with very long shutter times using Bulb anyway. It will all depend now on how much of the foreground would you want to include so the more foreground, the wider the focal length should be.

Tamron AF 17-50mm F/2.8 SP XR Di II VC (Vibration Compensation) Zoom Lens is better than VC and so much cheaper. But since this is gonna be my carry around/travel lens I decided to get the VC version. I love visiting museums and carrying tripod for me is inconvenient for me especially if I'm tagging along with me a toddler(my son) when we're traveling. Some countries also don't allow the use of the tripod in public and some places don't allow the use of flash.VC helps very well also when taking handheld night shots without using a flash
