Vixen Collimating your R200SS - Manual

How to collimate the R200SS
First loosen all the three collimation “push” screws and tighten the other three collimation
“pull” screws on the primary mirror cell completely to “reset” the primary mirror to a
position where the primary mirror is placed closely to the mirror cell.
1 Remove the blue cap on the center of the four-vane spider to access adjustment
screws for collimation. Loosen the fixing screw on the dead center of the spider to remove
the secondary mirror holder with the mirror. There might be some washers on the center
fixing bolt with which the secondary mirror holder is attached and please take care not to
drop them onto the primary mirror.
