Harder to discern without a telescope is the reflection nebula surrounding the cluster. Emission Nebulae. Many nebulae have high-energy stars inside, or a massive explosion in their past.

This emission is strongest under conditions which are intermediate between those in the interior of nebula and those in the dense cloud.

NGC 1858 is also an emission nebula, which is a cloud of interstellar gas that has been ionized by ultraviolet wavelengths radiating off of nearby stars.
