Description

Three panel Mosaic featuring RCW114 in HaRGB, from Melbourne.

This huge but very faint nebula has rarely if ever photographed by amateurs.
Looks a bit like Indiana Jones'whip :)

It was originally thought to be a ring nebula surrounding the Wolf-Rayet star WR 90, expanding into a pre-existing cavity created by the supernova remnant 343.0-06.0. However, current research suggests that is much closer to us than WR90, so is an Ancient SNR in it's own right.

It's big (and dim) too, this is now 1/2 of the region in the FOV!
For the curious it's located next to Sargas in Scorpius, 345.07, -6.445
The Glob at the upper left is NGC 6388

27 hrs - 54 x1800sec subs - Ha3nm
11.5 hrs - 69x600sec subs RG&B

Taken from my light polluted suburban backyard in Melbourne, Australia.
