Hi Peter. Thanks for your input. I actually ended up trying it out recently, and whilst I didn't get the results I wanted, that was more from a poor processing technique, rather than the hardware side which was easy to setup.
That said, I only did it because my mono filter wheel wasn't working so I just swapped the camera out for the ZWO.

Rotation is actually really easy to figure out. I use NINA and it got me back on the right rotation within 2 minutes.

* swapping cameras would inevitably cause image train rotation and that would mean compulsory guide re-calibration.
So I’ve decided to stick with just the mono camera in place. This wasn’t my original plan but as this hobby evolves I find surprises and re-thinks along the way!

Hi Chris
Valuable info, thanks! The flats thing is indeed a good point, though I guess you're taking even less flats (if you're breaking down the setup each night) since you only take them once for the camera rather than for each colour filter)
