I use my TMB80 and my TV85 on an AT Voyager very comfortably. I've also had my long tube 90mm f/11 on for a bit. I've mounted the Voyager arm at the 45° angle and it works just fine for me just the way it is. I really don't see the need to do anything else to this mount. Slow motion controls work well in both axes. I've been doing all viewing seated, which is far more comfortable for me.
