The eyeball operates in photopic, metopic, scotopic vision ranges.
Under a dark night sky, it takes about a half-hour to fully dark adapt into scotopic vision, and only off- pupil regions of the retina are capable of seeing the most feeble light source.
Every time you blink, you interrupt the photons falling on your eyes.
And you 'arrest' saturation.
Between 'blinks' the retina will begin again to absorb the light, then you blink again.

The cryogenically-cooled, charge couple device in the digital camera, strapped to the telescope and clock-drive, German Equatorial Mount never 'blinks.'
Photons can fall on it all night, 'saturating' each segment of the entire visible wavelength spectrum.
We can't experience what the camera does, but that's the whole point.
Extrasensory perception!
