Well camera exposure settings for daylight would have made it impossible to photograph the stars and the daylight bathed surface in the same shot, even worse with the cathode ray tube based video systems they used.

However, the human eye could easily cope, as any human can attest. The human eye takes about 15 minutes to saturate with visual purple enough to maximize night vision capable of picking out another aircraft against a sky full of stars, from 50+ km away. Without the light scattered by the atmosphere, all they would have to do to see a lifetime of stars would be to glance up or mask the horizon with their hand and the universe would come alive to the naked eye instantly.

What did the crew say about the breathtaking view?

Armstrong : "..I dont recall"

Collins : "I dont remember seeing any"

They never expected THAT question, look at the body language.
