Ancient Remnants - RCW114

RCW114 in HaRGB, from Melbourne.

Poking around in Galaxy map, I came across this huge but very faint nebula that is rarely if ever photographed by amateurs.

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 only 1/4 of the region in the FOV - maybe another mosaic required!

It's an awesome looking target, but rarely (if ever) photographed in colour. I love the glob at top left too

I scoured the web but could only find references to two images, one here on IIS by DVJ and one on Astrobin by John Gleason.

For the curious it's located next to Sargas in Scorpius, 345.07, -6.445

Big one HERE

7 hrs Ha3nm - 1800sec subs - could do with a lot more data too
8x600sec subs RG&B
