mmm... triangle centre spots.. that's a decent idea. hmmm..
the problem i've got at the moment is i'm kinda fumbling through collimation.. which is why i need an assistant. I don't grasp yet which knobs move the mirror in which direction.. so colliamtion with an assistant at the moment goes a little like "turn that knob.. oh.. no the other way.. ok.. now try the lowest knob.. ook.. no back the other way"
so a triangle centre spot would be great for that. If i was to re centre spot with a triangle.. would it be recommended to remove the old circle centre spot first.. or just place the triangle over it.. if it was to remove the old one.. how would you go about it?
