Here is a bit closer in view of RCW114 that Andy has imaged part of. Its the faint nebula in the shape of a heart off to the left.
To the bottom right we have NGC6188 which is commonly imaged. About midway up is the Wolf Nebula and it looks to be on the back of a large bird.
Above that is another nebula that looks familiar but I am not sure of its name, I'll hazard a guess its the Seagull Nebula.
I have this one in colour as well. Quite hard to process for some reason.
My very expensive telescope here was a $120 Pentax 67 165mm F2.8 lens at F2.8 for the Ha. Camera is a FLI Proline 16803 which is almost medium format in size (36mm square).
I'll post the colour version as well. I think it came out best in Ha though.
I guess no one images it because its so huge. Its way too big for an FSQ image without doing a multi panel mosaic with a large sensor.
I found one little reference to RCW114:
"This huge but very faint nebula is probably a ring nebula surrounding the Wolf-Rayet star WR 90, expanding into a pre-existing cavity created by the supernova remnant SNR 343.0-06.0."
This paper here suggests its a supernova remnant in its later stages (Vela SNR is considered young). This seems most likely as it looks a lot like the Vela SNR.
