The Core Of Cat's Eye Nebula (猫目銀河の中心部) NGC6543

I received a lot of advice from Mr. Watanabe in Niigata regarding the previous survey shooting, so I added about 3,800 new shots.
Mainly by repeating Combine, Masked Stretch, and HDR processing, I was able to catch up little by little.
I don't know exactly how many frames I ended up using because I didn't take a log, but I think the 2 second frame is about half the number of shots.

主にCombine、Masked Stretch、HDR処理の繰り返しでちまちま追い詰めていった。
