Description

I had long harbored the itch to image NGC6543 deep enough to reach the fuller extent of its eject envelope, something which I didn't do in my previous encounter with this PN. Now I kind of scratched this itch but found the task of properly visualizing both core and envelope while creating a balanced view of the wider field rather daunting. I'm especially unconvinced of the field stars rendition as the extreme non-linear stretching applied using a rather wide range of tools wouldn't allow to compress the halos at all. Attempt to shrink said halos brought nothing but frustrations. Note even RC's StarXterminator could cleanly seperate the PN's core from the stars themselves. And not for the first time. Be as it may, this is my best rendition to date.
