The Cat's Eye Nebula (猫目星雲) NGC6543

The other day's core part was overexposed, so I had to start over from the shoot. Looks like it'll be a bit of a Lucky Image.
The sky was clear last night, so I took pictures of the pale surroundings, as opposed to the core.
This also caused a problem. The bright core part has thick spikes.
It's gone.I think I'll reshoot it with C11 next season.

先日のコアの部分は露出過多で撮影からやり直している。ちょっとしたLucky Imageになりそうだ。
