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.

前回のサーベイ撮影に対して新潟の渡辺さんから色々アドバイスをいただいたので、新規に3800枚弱撮影を追加した。
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。
LOGを取らずにやっていたので最終的に利用したFRAME数は正確には不明だが2秒のFRAMEは撮影枚数の半分くらいだと思う。
