Herbig-Haro Objects Near The Cosmic Keyhole Nebula In Orion ( HH1,HH2,HH3,HH35,HH36,NGC1999)
Close-ups reveal the dark Cosmic Keyhole Nebula, while wide-angles reveal the bright 13th Pearl Nebula.
Hubble's close-up photos made it popular, but wide-angle photos that include the surrounding blue and red gas clouds are also popular. After some research, I found that there are several Herbig-Haro objects scattered around the nebula, but there are very few photos that focus on them, so I edited this one to make it the focal point.

Close-upで見ると暗黒のCosmic Keyhole Nebula 、Wideで見ると明るく輝く13th Pearl Nebula。
HubbleがClose-upを撮影してメジャーになったが、周辺の青や赤いガス雲も含めたWideな写真も人気がある。色々調べてみるとこの星雲の周辺にHerbig-Haro天体がいくつか点在するが、それにフォーカスした視野での写真はほとんどないので、それをポイントにした画角編集をして見た。
