I use an 8” f5 newt too and kept my finderscope but added a heavy duty losmandy dovetail bar across the tube rings to mount my 60mm Orion guide scope and ZWOASI120MM guide camera
Solid as a rock no issue with flexure
I started with using a 50mm Orion guide scope “shoe mounted” off set but got sick of swapping my finder and guide scope over all the time. Now I’ve kept my finder in the shoe and added my guide scope to the central axis of the OTA , works well no issues
See attached photo of my rig
