If I have a 2,000 candelas red light source under normal rural atmospheric conditions at what distance would I expect the source to no longer be visible to the eye?

Atmospheric extinction of light is the phenomenon where light is scattered and absorbed as it passes through Earth's atmosphere, resulting in a decrease in the amount of light reaching the Earth's surface.
Atmospheric extinction is caused by various factors, such as scattering of light by gas molecules, dust particles, and water droplets in the atmosphere, as well as absorption of light by gases and aerosols.
Atmospheric extinction can make it difficult to observe objects in space as it reduces the amount of light reaching Earth's surface. This can result in dimmer and less detailed images, especially for objects that are far away or faint.
Yes, scientists use various techniques to correct for atmospheric extinction, such as using filters to block out certain wavelengths of light that are affected by extinction, or using mathematical models to account for the amount of extinction in their observations.
No, atmospheric extinction varies depending on factors such as altitude, weather conditions, and location. For example, high altitude locations tend to have less extinction as there is less atmosphere for the light to pass through, while locations with high levels of pollution may experience higher levels of extinction due to increased scattering and absorption of light.
