Frank,
To me the distances in the photo are distorted as for example:
1) in the stellarium image, the distance from C(assiopea) gama to C eta is greater than C eta to C alpha while
2) in the photo those distances are opposite.
I know next to nothing about the I phone optical system but it is an amazingly short focal length and likely has a lot of distortion as a consequence.
