The nebula is named after its main star, λ Orionis, a blue giant responsible for the ionization of the surrounding material.
The broad nebula shown is not visible unaided, with binoculars or small amateur telescopes.
Orange giant φ2 Orionis, while appearing to be surrounded by the Ring, is merely a foreground object at only about 116 light years from Earth.
HD 34989 is a blue-white main sequence star, visible magnified only, just outside the Ring.
It has a small nebulous cloud more geared towards the near-infrared than other parts of the neighbouring ionized regions across the Ring.
