That could be, the purity adjustment wasn't fun and maybe not 100% perfect, I'd call it 99%. Not only did the yoke not move enough to get to where I could see where the red spot (in it's entirety) was, but the lateral magnet/purity ring assembly is either a weird design that puts the rings behind the magnet, or it was installed backwards. I do wonder if it can be turned around so that the rings are easily accessed. Of course, that would put the clamp up near the convergence magnets. I used a permanent marker to indicate exactly where this was positioned, but I could imagine having to circle back to fixing purity when reassembled, anyway.
This is the side that has been facing out:
The rings are tucked behind. I haven't seen another CCII photo with this particular assembly. The grainy pic in the SAMS seems like it *might* be the same, though.
