RCW 133 (or GUM55) SHO

Rodgers, Campbell & Whiteoak (RCW) catalog of H-alpha emission nebulae in the Southern Milky Way.

RCW 113, also known as Gum 55 is a large diffuse nebulae region associated with NGC 6231 open cluster.

The two bright stars to the left of NGC 6231 are zeta1 and zeta2 Scorpii.

The Prawn Nebula (upper right, with blue hues), also known as IC 4628, is an emission nebula around 6,000 light-years from Earth.

To the right of IC 4628 there is another open cluster NGC 6242.

The Wolf or Fenrir Nebula (SL-17), at 10 o’clock position in this image, is a dark nebula of dust and gas hiding the background stars.

The Dark Tower (SFO 82) is the prominent bright-rimmed cometary globule, about 1.5 degrees away from NGC 6231 and Zeta Scorpii. The shape of this massive structure of cosmic dust resembles a dark tower emerging from the star field background.

Most of these objects lie about 6000 light-years away in Scorpius, near the Sco OB1 association of stars.
