Keith...I just spent a bit of time with a friend who also did not know if the springs were used to lock in place or not...can't find it now, but somewhere in cloudy nights...we went over a description there as well and now understand what it is that your saying about collimation.
One question though ... Lets say I have taken the mirror and cell out for a clean and now have to put it back in ... at which point do I line up the collimation bolts (springs) ...
We got to talking about how the weight of the mirror would increase at the bottom half as the scope moved through its arc ... and wondered about how this would play on the arrangement of tight and semi tight springs...We played through two arrangements in our head with the 1st being; the tighter spring (to be left untouched) dead center on the lower half of the mirror facing the front Board of the rocker box, when scope fully erect and the two springs with give in them, evenly spread on the opposite side. The 2nd arrangement just in reverse with the two collimation bolts evenly spread across the center point of the lower mirror and the tight spring dead center opposite to that.
Is there at all a preferred way to position the cell when fitting it and the mirror back into the scope?
