Hi, I see you are making this z axis tilter:
https://astronomy-imaging-camera.com/product/t2-tilter
As you can see from p. 11 and p. 15-16 and especially p. 19 of this manual of a Hotech advanced Schmidt Cassegrain laser collimator array
https://www.astrosirio.org/wp-content/uploads/2011/08/ACT-Manual-V9_3D.pdf
the collimation of Schmidt Cassegrains (and also Richey Chretiens) would benefit from a tilter that can tilt in all 3 axes. This is because some tubes have a primary that is misaligned to the visual back.
In order to correct this, one should not just move the z axis but also the horizontal and vertical axis.
Can you make an m48 and t2 tilter that can move all 3 axes?
The reason for this proposal is this:
In Celestron Edge hd's, one can compensate such a misalignment of the primary mirror with the visual back by aligning the schmidt plate to the primary, and then changing the angle of the secondary.
As long as you are working with the pure sc, where you can easily collimate with the airy disk over applications like metaguide, this works.
But if you add a reducer on the telescope, you would need a different collimation. Then you do not see the airy disk because of the reduced focal length.
Working with the hotech collimation laser requires in the case of a reducer that the secondary is set parallel and all axes are aligned because the reducer changes the sensitivity of laser reflections....
Same is for an RC. This also must be aligned in parallel. If the scope has tilt in some axis that can not work.
For aligning this exactly one would also need a 3 axis tilting adapter.
Unfortunately, no one makes such an adapter yet, even though it would be easy to produce.
Hotech advises to buy an expensive focuser with such a tilt mechanism available.
But why buy a focuser if this can be done with adapter plates?
Best regards...
