Globular star clusters look pretty good from moderate light polluted areas. M-13 is one of my faves to see from central Tucson. There are quite a few globulars to see. The ring nebula can be a good one too. Some bright glaxies like M-81, M-82 are visible.
In winter, the Orion nebula is THE gem of the sky in most any sky brightness. A sky glow filter helps improve contrast too.
Good luck & clear skies.
