Consider a billowing nebula of hydrogen and helium gas slowly collapsing to form a new star. It appears stunningly unreal. But why present this image if it doesn't capture what the naked eye could see?

The Limitations of the Human Eye

It's crucial to recognize the human eye's limitations in perceiving certain aspects of the universe. For example, a nebula comprised of sparse gas against the vacuum of space would be too dim for the human eye to discern; it would simply appear as darkness. Moreover, the human eye lacks the ability to perceive the frequencies of light required to differentiate between different gases.

This leads to the ethical question of whether it is justifiable to portray the true nature of celestial objects in an altered manner.

Enhancing Celestial Images

In the realm of astronomical photography, capturing the genuine essence of celestial objects necessitates enhancing the images to make them comprehensible to the human eye. What we perceive as
