How to Find It

Locate Orion's Belt, the distinct line of three bright stars, and look just below it to find the three stars forming the 'sword' of the hunter; M42 is the fuzzy, glowing patch surrounding the middle star of this sword.

Observing Tip

If you are struggling to resolve detail in the bright core, use an OIII or UHC filter to increase the contrast of the nebulosity against the dark background sky.
