Running Man



Thought this was a cool picture of something that we can see with a pretty simple telescope.

Visible to the naked eye as the middle "star" in Orion's "sword," this spectacular object looks great through any size telescope and at any magnification.

Move north of the Orion Nebula to find the Running Man Nebula (NGC 1973-5-7). The two bright stars involved with the nebula are 42 Orionis (magnitude 4.6) and 45 Orionis (magnitude 5.2). Because the Running Man Nebula is a reflection nebula, observe it without a nebula filter. Its light is reflected starlight scattered throughout the gas and dust, not reddish light emitted by hydrogen (which a nebula filter transmits).
