My understanding is:
The TOA cell has 18 collimation screws on the front of it, 9 are for collimating the 'whole cell' in relation to the tube, another nine are for the alignment of the first element in relation to the second element.

If the whole cell collimation is out then the deeper recessed screw set can be used to collimate the whole triplet assembly. This can be done with the Tak collimation scope. However, if the issue is miscollimation between the front element and the second one, i.e. the less recessed 9 screws (3 cap screws for the 'pull' action and 6 grub screws for the 'push' action) one will need the specialised equipment not available here in Australia.

I guess the issue is to establish if the miscollimation relates to the whole cell and its relationship to the tube or an element within the cell being out of line.

That's my understanding from looking at my TOA and reading stuff ...... It is a lot different from the FS78/FS128 etc
Haven't seen this on any other cells.

Personally I would firstly check if all the screws actually have equal tension on them but firstly I would mark the screws and note if and how much any are loose by.
