I listed all of the equipment used for image acquisition at the beginning of my post.
Also when I processed the my data in PixInsight the images were plate solved and the results stated 668, so that is the reason why I said I needed to tweak the spacing between the ES 3” FF/FR. I think I am about 1 mm too close.
