To create your own twilight cityscape photos, you'll need just a few basics, camera, tripod, remote or cable release. You can also use the self timer on your camera. If your lens has vibration reduction or image stabilization, you can turn this feature off. Shoot in RAW format for the most flexibility during post processing. Choose a white balance setting that is complementary to your composition. With my Nikon D4, I use a white balance setting of 4000K to 5000K, or try the Fluorescent setting which can work beautifully with compact cameras.
