Thanks for that Rick.

Yes there is a bit but that is pretty close to what it looked like visually. I think the projection methods have their slight distortions and I tend to try different one to see which is best. The fence poles are relatively straight except for the background one so there is some distortion. Other projections may minimise that but they sometimes shrink the field of view as well.
