Hi all, I played around with a collimation bolt tonight.
A friend pointed me to a chinese telescope making forum where I spotted this design, you may have come across it before but as I am a relatively new atm'er it is new to me.
It is a pushpull bolt where the outer bolt screws in to the telescope back and the mirror cell sits on top of it. The center bolt goes through the back of the mirror cell.
To adjust, you unscrew the center bolt slightly and then turn the outer bolt to either raise or lower the cell. Once done the center bolt is tightened to make sure that the cell is pulled back firmly to the main bolt. I hope this explanation makes sense!
An allen key is used to turn the center and I will need to make up a different key which will fit in the slot of the large bolt to turn it.
