IC5067,HH555,HH563,HH564,HH565,HH566,HH567,HH568

I had a little left for an hour until sunrise, so I took a picture of the Pelican Nebula with SHO as the fourth target of the day.
The Pelican Nebula (IC5070) itself is a nebula that is loved and photographed by many astrophotographers, and since I take pictures every year, I focused on the area called IC5067 on the head of Pelican. saw.
Many people here take beautiful pictures with a 14-inch class long-focus telescope with an exposure of 15 hours or more, so I wanted to see how much I could see with a 1-hour exposure by 11 inch F/1.9.
While examining this IC5067, I learned that there are many Herbig Haro Objects (HH) in it. I wrote HH on the second photo right after Pre-Process.

夜明けまで1時間ちょい残っていたので、その日4本目のTargetとしてPelican星雲をSHOで撮影してみた。
Pelican星雲(IC5070)そのものは多くの天体写真家の方々に愛され、撮影されている星雲であり、自分でも毎年撮影しているのでPelicanの頭部にあるIC5067という領域に編集の焦点を当ててみた。
ここは14インチ級の長焦点望遠鏡で15時間以上露出して綺麗に撮られている方が多いので、Fast望遠鏡で1時間の露出でどこまで見れるか試してみたかった。
このIC5067を調べていると、この中には多くのHerbig Haro Object(HH)があることを知った。2枚目に
Pre-Process直後の写真にHHを記してみた。
