ts60 reducer

The 0.8 reducer-flattener from AliExpress giving 288mm. W i d e.

Spacing: 30 + 7 + 17.5 = 54.5mm which looks too close.

(EDIT: 12 + 20 + 7 + 17.5 = 56.5mm,  too far.

Gonna try 12 + 20 + 6 + 17.5 = 55.5mm)

Judging by the logic of the other flatteners, I should try closer still, 52.5mm, before trying expected normality at 56.5mm. Oh how I love refractors etc.
