      "You flap your arms and your feet start kicking
      Then you know you doin' the funky chicken"
      Which is possibly what the guys at the AAO were doing when they named this the 'Running Chicken' nebula!

      I've presented versions here with and without stars, as I'm still waiting for the clouds to clear to capture some RGB ones.

      Description: Version with RGB stars added. Given my LP conditions I used 20 x short 2min subs each Chroma RG&B. For those interested in the technique used, to boost the star colour "naturally" in PS I changed modes from RGB to LAB colour, then adjusted the curves in Channel B, which only affects Blues & Yellows, then back to RGB for the overlay in PS using 'screen' blend mode.
