Collimation free mirror is possible .
My Conical mirror has not been touched for three years since it was built except for when I made the focuser cage a rotating cage.
It has been over some rough dirt roads in the back of a ute.
The truss assemble does not disassemble thou so that is a concideration.
The conical mirror is located on a central stud and held in place by the stud with 4 O rings on the central hole, and a front retainer cap.
I have removed the mirror for various reasons and as long as it is replaced in the same orintation , does not require re collimation.
The Cell assemble is a 3 arm spider with push pull screws .
No floatation points , mirror straps or mirror retaining clips.
No springs here , once adjusted and locked thats where it stays , full stop end of story.
Very easy to adjust.
The black lock bolt is wound out a little to allow the silver adjuster to be free.
The adjuster is held in place by the nylock nut and is tightened just enough to allow the bolt to turn .
Simple but very very effective.
Once adjusted do up the lock bolts.
Actually you don't even need the lock bolts , but are there just to be sure.
