For some time have been fighting with NR's, which now past problem as have bought a tilter... On my Lunt 50 working like charm, no focussing problems which I were expecting.
Previous advices in the forum have helped me to solve ghosting and (partially) other issues like light distribution. Still not a fan of flats.

Thanks for all the great help, in return sharing with you some of my results of this morning shootings...
Hans.
