So given that I imagine it would be tricky to get it set but obviously some have mastered it.
The smaller APS sized ASI2600M or MC or QHY equivalent may be a lot less demanding.
For example with my AP RHA 305 F3.8, my QHY294M needs no adjustment for tilt. The QHY600M does and is a bit fussy about it. Not impossible (tilt never seems to be dead easy) but it will take a little while.

Of course you're absolutely right Greg: APS-c sized and smaller sensors will be much kinder to tilt as well as any other potential aberrations towards the edges of the image circle. The only downside is that you'd be leaving a lot of light on the table (~60% unused) compared with using all of the RASA 11's full frame image circle.
