I have a PMX in a Sky Shed POD which is 80 inches (203cm) at the dome rim.
This is measured at the level at which the scope slews so is the working level.
I can tell you that an RC 10 tube is about 62cm then you add the extension rings , focuser and camera. With my QSI I was struggling to slew, with the SBIG and the filter wheel and the AO8 I had to put everything far forward and balance really carefully, even so I had to remove some parts to cross the meridian so is not comfortable for an automated set up at all.
I actually thought about making a NW to NE "gate which is removable so I can slew with more abandon, but it would structurally alter the walls.
I would guess in a 2m30cm dome, even if you place exactly central, with a metre long OTA plus cameras etc you would be squeezing it.
You could, if needed, I suppose, store the scope in a tight against the dome position and when ready to go, whack it straight into the dome slot-plenty of room there with the snout in the air!!
