The reality is that our eyes have a huge dynamic range from starlight bathed scenes to Sunlight. It is almost impossible to portray this realistically with 8 bit or even 16 bit depth.

The aim of astrophotography is to try and convey information about the object. Stars record in less than a few seconds. Dim emission nebulae and reflection nebulae and illuminated dust can take many minutes. Dust in front of stars or emission nebulae is just very dark.
