Final

I found a clear nights and slowly collected signals for 20 minutes on some days, 30 minutes on other days, and 1 hour on other days. Also, using the data from last season, I managed to reach the planned exposure time of about 15 hours.

Small Eagle (the pillar of creation) can't beat Hubble, so I pulled out the surrounding objects.

(1) The glowing eyes of the black wolf's face in the upper inverted triangle and the dark clouds around them

(2) Jack-in-the-box kid wolf popping out from the left

(3) The dark nebula on the left and the edge of the blue nebula

(4) Multiple ripples running from upper left to lower right in the gray nebula on the center right

I read a research presentation that the star in the upper right of this photo has traces of a supernova explosion about 8000 years ago, and that the shock wave may not exist now as the pillar of creation. Since the distance to this nebula is about 7000 light years, it seems that the supernova explosion could be observed from the earth 1000 years ago. Will we not be able to see this in the next few thousand years?

It's a waste.

晴れ間を見つけて、ある日は20分、ある日は30分、ある日は1時間とゆっくりシグナルを集めて、昨シーズンのデータも活用して何とか予定の総露出時間の約15時間に達した。

Small Eagle（創造の柱）はHubbleに勝てないので、周辺のObjectを引き出してみた。

（1）上部の逆三角形の黒い狼の顔の光る目とその周辺の暗黒雲

（2）左から飛び出してきているびっくり箱の子供の狼

（3）左の暗い青雲と青い星雲の堺のEdgeの部分

（4）中央右のグレーの星雲に左上から右下に幾重も走る波紋

この写真の右上の方に有った星が今から8000年くらい前に超新星爆発した痕跡があり、その衝撃波で今は創造の柱は存在しな可能性があるという研究発表を読んだ。この星雲までの距離は7000光年位なので、1000年前に地球からはその超新星爆発を観測できたらしい。何千年後か先にこれは見れないのであろうか？

勿体無い。
