North America Nebula NGC7000
The North America Nebula is large, covering an area of more than four times the size of the full moon; but its surface brightness is low, so normally it cannot be seen with the unaided eye. Binoculars and telescopes with large fields of view will show it as a foggy patch of light under sufficiently dark skies.
Cygnus's Wall is a term for the "Mexico and Central America part" of the North America Nebula. The Cygnus Wall exhibits the most concentrated star formations in the nebula.
The North America Nebula and the nearby Pelican Nebula, (IC 5070) are in fact parts of the same interstellar cloud of ionized hydrogen. Between the Earth and the nebula complex lies a band of interstellar dust that absorbs the light of stars and nebulae behind it, and thereby determines the shape as we see it. The distance of the nebula complex is not precisely known, nor is the star responsible for ionizing the hydrogen so that it emits light. If the star inducing the ionization is Deneb, as some sources say, the nebula complex would be about 1800 light years distance, and its absolute size would be 100 light years.

Having a look through the subs the smearing is apparent on each frame. It is a bit of an oddity though as other images with the same lens are pretty much free from coma at f/3.2 with a APS-C sensor. Even full frame controls coma really well until the extreme corners. Seems good through the focal range too. For example Looks great at 140mm captain-marmote.deviantart.com… I highly recommend getting one
The mount had just come out of 1 year or more of hibernation however and was acting a little weird, couldn't track sidereal rate on its own for a while, couldn't get guided tracking working over 2mins either, unsure why. Probably didn't do a great polar alignment but things are working as they should now.
Mount is an NEQ6, due for a bit of an overhaul I think! But it works without issue. What equip are you running?
