RCW 57E (Ugly name -- Pretty Nebula)

RWC 57E is just below eta carinae, this is the eastern section.
i was going to hold on to this for a while but decided it might be of interest from a processing point of view, ive been working on some techniques to separate the item of interest from other stuff, this was the seventh try before i got one that worked reasonably well.

everyone has there own way of doing the processing thing, but i dont see much of the before/after so dont really know how effective that persons processing has been. ive included the stacked out of DSS image and the finished item at the same scale so you can compare if you want to.

this is a stack of 12 6min exposures at 800 iso with a cannon 300d modded, 12 inch newt, no filters other than uv/ir. i had more exposures but culled out those with movement as the wind was not the best.

Any proceesing suggestions/ comments welcome.
