Hi Mikey, I went through and picked out a few shots from relatively short exposures at low iso to longer night shots at higher iso. The D60 sensor isn't terrible, but there are better. My advise is to crop as little as possible, post process as little as possible (sharpening, contrast and shadow recovery really brings out noise) and apply noise reduction if it really bothers you. In other words, correct exposure is the key to keeping noise levels low. Hope these help for a rough guide.
All D60, no noise reduction, minor post processing
Pedernal at sunset, 1/8 f6.3 iso 100 16-85vr handheld, bit of noise in the sky, not objectionable in prints
Fireworks, 12.8 sec f5.6 iso 100 18-55vr, tripod
Most of my fire works exposures are from 2 to 6 seconds but I wanted some foreground detail, plenty of noise and streaking when magnified, but small prints are okay
Cassiopeia, 32.5 sec f5 iso400 16-85vr, tripod
about 50% crop, noise visible but I don't mind
Pines at night, 82.5 sec f/2.8 (?) iso800, manual focus 55mm Nikkor 1.2 lens
I believe the camera's NR kicks in at 800 iso, Rather heavy pp on this one, but no pp NR
