I have been working these days to go (for the first time) to the Newton configuration of my scope. It all looks good, but once tested on the stars I found out that there was no way to get in focus. I would somehow need to go deeper with the corrector into the focuser. This would, however, result in the corrector getting into the light path.

Reducing the distance between secondary and primary is not an option, as it would prevent me from using the system in Cassegrain mode.
I wonder if I could remove one of the outer rings which right now sits between focuser and the camera adapter (it is located on the outside of the corrector). Any ideas?
By the way, my DDM85-XL is now loaded, on the scope side, with about 115kg of weight (tube, camera and counterweights), and runs smoothly
