The Caldera Rim Of Pelican’s Head (ペリカンの頭部のカルデラの様な星雲)

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.
