Each week, Astronomy magazine Senior Editor Michael E. Bakich, a master at explaining how to observe, posts a podcast about three objects or events you can see in the sky.
Planetary nebula NGC 2022 lies two-thirds of the way from Betelgeuse (Alpha [α] Orionis) to Meissa (Lambda [λ] Orionis). It glows softly at magnitude 11.9 and measures 39" in diameter.
