North America Nebula NGC7000 and Pelican Nebula IC5070

Triggered by Astrometry.net I restacked my pictures of the North America Nebula using DeepSkyStacker. Using CS4 I changed my way of editing the stacked result :

1) slightly sharpen the picture using unsharp mask
2) narrowing each Red, Green and Blue curve
3) narrowing each Red, Green and Blue level

The result is much better then my previous editing and the "head" of the pelican is clearly visible.
The pictures are taken with Nikon D7500 on TALAPO 80/480 f/6. A total of 11 pictures, each 30s with different ISO levels.
