Suppose you had a clear, moonless night. How many stars could you see with the eye alone?
If you step outside at night from a bright room, you won't see many stars at first. It takes up to 30 minutes for your eyes to adapt to the dark.
Considering all the stars visible to the eye alone approximately 2,500 - 5,000 stars - would be visible from Earths night side. However, a fraction of those visible stars would be lost in the haze and city pollution on your horizon.
You also have to take into account the brightness of your night sky. Even on a moonless night, the glow of lights from Earths surface brightens the sky.
Under absolutely perfect conditions of darkness and sky clarity - a young to middle-aged person with normal vision should be able to see at least a thousand stars.
Perrys Victory is a great place to learn about and enjoy the splendor of the night sky. At 317 feet you will experience a unique adventure in stargazing.
