NGC2392（エスキモー星雲）2022-01-14
ラッキーイメージング方法で5,000フレーム（Shutter=671.8ms Gain=542 (83%)総露出時間/3359.079s）50％をスタック。
気流が悪く内部構造がぼけてしまいましたが、この手の天体撮像には有効と思います。
NGC2392 (Eskimo Nebula) 2022-01-14
Stack 50% of 5,000 frames (Shutter = 671.8ms Gain = 542 (83%) total exposure time / 3359.079s) by the lucky imaging method.
The seeing was poor and the internal structure was blurred, but I think it is effective for this kind of astronomical imaging.
