Norma Rose Observatory, Queensland, Australia.
I found out about this
object in David Malin's Invisible Universe. Interestingly,
it is unnamed nebulosity situated about 2 degrees west and north
of Zeta Scorpii at the bottom of the scorpion's tail centered
at 16hr 46m and -41 deg 10m. This month's image is a redo of the
May 2001 Image of the Month taken from Astro Works in Aguila,
Arizona. This area passes directly overhead as viewed from southern
Queensland. South is up. A 13nm Ha filter was used for the red
channel information in this lrgb exposure. Below image is a cropped
portion at 100% magnification.
