Which element primarily produces the deep red color characteristic of many emission nebulae via the H$ ext{alpha}$ transition?

Answer

Hydrogen

Hydrogen, the most common element, produces light in the deep red end of the visible spectrum through the H$ ext{alpha}$ transition, which is often intense enough to overshine other features in large emission nebulae.
