New moon is ideal, but the usable window is wider than most people think. LightCast StarCast scores tonight's conditions using moon phase, moon position, cloud cover, and light pollution.

Moon phase tells you how much of the moon is illuminated. Moon position tells you whether it's actually above the horizon during your shoot. Both have to work in your favour. A thin crescent moon that rises at 11pm still limits your window. A quarter moon that sets at 9pm leaves the rest of the night dark.
StarCast scores tonight's conditions using moon phase, moon rise/set times, cloud cover by layer, and light pollution at your location. When conditions line up, push notifications alert you before the window opens โ so you can plan around the forecast rather than check it manually every night.
