New Main: Light Meters
Light meters are devices used by astronomers to measure the amount of light in a particular area of the night sky. They are useful for determining the brightness of stars, planets, and other celestial objects, as well as for assessing the quality of the observing conditions.
Astronomy light meters work by measuring the amount of light that falls on a sensor or detector. Some light meters are designed specifically for astronomical use and are sensitive to the types of light that are commonly found in the night sky, such as red light. These light meters may also have features like dark-sky filters, which block out unwanted light pollution and improve the accuracy of the measurements.
Astronomy light meters come in a variety of designs and sizes, from handheld models to larger, more sophisticated devices. Some light meters are designed to be attached to a telescope or other astronomical equipment, while others are designed to be used separately and pointed at the sky.
