I am a bit unclear, but how does one scope “cut” through light pollution. I thought the sensor was purely a passive device catching photons directed towards it, acquiring signal. The result contains light pollution, noise, and the intended target signal. How is the light pollution signal removed from the acquired sub in the OTA?
