IC5070 - The Pelican Nebula - "Neck"
detail
I found the Pelican's neck region very interesting.
The following detailed photo covers the area from the
above picture marked by red rectangle.

had to stop imaging in 8.10. because clouds
covered the whole sky. That's why I finished my
imaging a day later.
