Jason, as usual, you are trying to make it simple. But I want to cut and drill things and fit knobs and chains and sprockets!
I put my hot spot on in a rush and didn't orient it. The way the mirror is slung, I have to do a little work to let me rotate it, but I will do this, next time I take it out. But I did make up a drawing to show how the image moves with the two collimation bolts that I use to adjust the Primary.
