If you watch carefully, a system has the same brightness no matter where you are. According to the Inverse Square Forumla, a star’s brightness should follow along the equation: B = L/(4πd^2) where B is brightness, L is the luminosity in Watts, and d is the distance.
So if the distance of d is doubled, then brightness should be reduced by 1/4th. However, the light is the same brightness no matter how far in the system you are from it.
CCP, this is not a hard thing to change. It adds dynamics to the game. And it saves people a from having to look for objects to stick between stars and your camera cause they’re really bright all the time.
