The Cat’s Eye Nebula - NGC 6543

The Cat’s Eye Nebula or NGC 6543, is a planetary nebula in the constellation of Draco. Structurally, it is one of the most complex nebulae known, with high-resolution Hubble Space Telescope observations revealing remarkable structures such as knots, jets, bubbles and sinewy arc-like features. In the center of the Cat’s Eye there is a bright and hot star; around 1000 years ago this star lost its outer envelope, producing the nebula.

NGC6543- Cat's Eye Nebula LRGB
Well this was a stuggle. Why I picked this target on the shortest nights of the year when we don't have true darkness, I'll never know. I have to admit I gave up processing this image. Not to happy with the stars and there isn't as much detail as I expected. Perhaps I was expecting to much. It had to be stretched quite a bit and I had to apply alot of NR so this is probably why the detail isn't there. Tried to cut down my imaging time by doing the RGB in bin 2 and this seems to always give me some issues. Think it's time to image some Ha. The Cat's Eye Nebula is a relatively bright planetary nebula in the northern constellation of Draco, which was discovered by William Herschel on February 15, 1786.
