網状星雲(Veil Nebula 、NGC 6992-5、NGC 6960)を木星観測の前、撮りました。大きな散光星雲なので一部の視野ですが赤と青のきれいな色彩です。弱い画像処理でコントラストを抑え優しい色彩に調整しました。薄明中の低い高度の撮像でしたが次回は天頂の位置で撮ってみたい!
明るい東側がNGC 6992-5 (C33) 、西側がNGC 6960 (C34) であり、数万年前に爆発した超新星残骸のガスが毎秒100kmで広がっている姿だと考えられている(ウィキペディア(Wikipedia)

I took a picture of the Veil Nebula (Veil Nebula, NGC 6992-5, NGC 6960) before observing Jupiter. Since it is a large diffused nebula, it is a part of the field of view, but it is a beautiful color of red, blue . Weak image processing suppresses contrast and adjusts to gentle colors. It was a low altitude image in the twilight, but next time I would like to take it at the zenith position!
The bright eastern side is NGC 6992-5 (C33) and the western side is NGC 6960 (C34), and it is thought that the gas of the supernova remnant that exploded tens of thousands of years ago is spreading at 100 km / s (Wikipedia (Wikipedia)
