2. Use Manual mode to capture stars.
If your goal is to photograph stars, then a moonless night is when you want to shoot. If you don’t have the luxury of waiting for a moonless night, then it is possible to shoot away from the moon, or you can time your shoot for before or after the moon has left the sky. The added light from the moon can wash out the stars, drowning them in light. When trying to balance the exposure at night it is best to use the settings that offer the most control. Camera light meters are designed for daytime use, and although sometimes I use aperture priority to get a quick suggestion from the camera, I always switch to Manual, so that I can fine-tune the exposure, and so that it won’t change between shots without my input.
