Why not look at reducing a more modest scope with the ASA reducer corrector?

Hi Peter,
thanks for all the work you did there.
It proves the 12" f/3 can't work with a 2" focuser as I thought -
& neither can the 10" f/4.
Notice TS sells Newts. with the bigger focusers:

It doesn't matter what option I choose I am still
unable to use my QHY9 camera because of the back focus problem.
No 1:1 corrector has 70mm of back focus.
I don't think I can upgrade.
By the way I checked my 8" f/6 Newt. om Dave Keller's program
& it comes up as a perfect system.
cheers
Allan
