Pelican nebula as a zoom in series

I have shot many targets with several focal lengths.
Due to that I will publish some of my material as image sets, with different field of view and level of details.
The fractal nature of our universe stands out nicely in this way and it will make the orientation easier.

Many times it's difficult to understand the image scale of astronomical images.
Due to that I have added a "Moon circle" in the images to show the angular scale in a sky.
The full Moon has an angular size of ~30 arc minutes, that's equal to ~0,5 degrees.
