Orion Nebula in H alpha
This image was taken in 2010 and has been reprocessed to give a more detailed result. The Orion Nebula is a lovely sight visually and can be strikingly beautiful when imaged in the light from the rich field of excited hydrogen gas that is feeding star formation in its core. Note the 4 trapesium stars in the core.
