Getting the spacing right can indeed be a faff. I’m sorted also with my RASA 8: a 7.5 mm spacer has given me nice circular donuts all the way to the corners of my largest sensor. My calculations suggested 12.5 mm would be required to get me there, but no – trying and testing got me to the solution. Phew!
