Very fine indeed. Beautifully sharp. You've got quite a bit of the "cygnet" to the far left of the Swan, so quite deep.
Bottom right corner shows a faint doubling of the stars. Not a guiding issue (congratulations there!!), because the rest of the field is fine, and not tilt or coma, a definite double image. So probably a registration problem during stacking.
Best,
