Single Exposure Project #4 1 minutes Great Orion Nebula (M42)

The four single shot is a 1 minute exposure of Great Orion Nebula (M42)
Since this nebula emits various Signal colors, it loses color in the Narrow Band.
It depends on the purpose, but this time I shot with only a light pollution filter. Therefore, the exposure time of 1 minute was the limit in the sky here.

4回目の1枚撮りは1分間露出のGreat Orion Nebula (M42)
この星雲は多彩なSignal色を放出しているので、Narrow Bandでは色を欠損してしまう。
目的にもよるが今回は光害フィルターだけで撮影。よってここの空では1分の露出時間が限度だった。
