It's some part of NGC3077. "Phoenix" was mentioned as part of the target name but I'm not sure what that means.

I don't suppose this is a very visually interesting image. I found that there were 5 different filters provided for this so it was mostly an experiment on figuring out how to combine them when I've only got 3 channels to work with. What I ended up doing is creating 5 layers, assigning the 5 separate channels their own masks, and then setting the layers to Linear Dodge (Add) which allowed me to control the individual contribution of each channel channel on the fly instead of trying to tinker with it in grayscale.

I couldn't agree more!!!!!Also, man, I wish more images were shot with three channels. There's a plethora of wonderful dual filter images out there but they leave the colors a little boring at times.
Yes, it's an x-ray source. I wasn't ambitious enough to figure out where the x-rays were. I did try to find an image that I could add and overlay the x-ray source but I couldn't find one. Ha filter was used but the light was equally bright or brighter in 555 which I mapped to a slightly yellow green so it turned the nebula yellow. Totally forgot to list the filters that time.

(I note that emission nebulae look green in your image. Does that mean that no Ha filter was used?)
