Roughly adjust the center bolt and the orientation of the secondary holder until the
secondary mirror is centered by being viewed from the focuser draw tube
•
Adjust and tighten the three collimation screws.
When installing the holder into the spider, you should orient the 3 collimation screws
evenly between the vanes.
Then
make sure that the secondary mirror is roughly oriented towards to the focuser.
This can be done by loosening all the collimating screws a small amount and rotating the
mirror, the secondary baffle and back plate relative to the adjustment plate and mounting
stud. The tighten the collimation screw after the adjustment.
Then make sure the secondary is roughly at the right height by adjusting two center nuts
on the Stud. Tighten the center nuts after the adjustment.
No precision adjustment is need at this stage.
