Thanks Theo - If I was to use a WO 2" APO field flattener, 0.8x on the Orion ED80 [F7/5] am I likely to get any vignetting on the QHY8 sensor or It's all good?

The only time you will ever remove the filter is to clean the sensor or replave the filter with another filter, eg. UVIR Block to clear filter.
The filter has a T thread on the front so you can mount accesories to it.
I too use a MPCC and use a spacer from the Meade f3.3 reducer kit.
Although you can get spacer kits of many different lengths, their may be someone there that is not using one of theirs from their own kit that may sell one.
Theo.
