looking for piggy back improvements

Hi

Just been out in the observatory,and looking at the piggy back set up on scope (see pic),I am wondering what others have on their scopes.and how to
go about keeping a heavy camera lens closer to main tube.

I bought a manfrotto 484RC2 head,and had a engineer ream out the hole on
the vixen carry bar and re-thread it 3/8,I put a 3/8 bolt thread in head,and all
fits well.When I use camera with kit lenses,it works well.

I have some heavier higher grade lens,I can use the above set up,but because of the weight,I have concerns-flexing,and the way it is ,the camera lens-along way from main tube,causing balance issues.Using carefully still getting reasonable results,But would like to get camera and lens closer to main tube.

Any suggestions?
