Here's an image I took of the Whirlpool galaxy in my backyard a few nights ago with an #evscope.
My backyard is not especially dark, there is a lot of #LightPollution. But the camera integrated the starlight for about an hour, and displays the background as black (with the light pollution removed).
Without light pollution, the background would still be black, but the galaxy have more details and would be more defined, because the signal to noise ratio would be much higher.
