Can cameras from different manufacturers produce mirror images of each other?

Tonight I was trying to align my RASA8/QHY268 FOV with my SY135/IMX571 FOV and it would appear one is a mirror image of the other. You can see I posed the above question but am I correct in thinking that the difference is caused by one being a lens system and the other is a mirror system? 
 

I guess APP will sort them out if I want to combine the data but it is a bit unsettling trying to compare the subs on the monitors. Maybe NINA can auto flip an image before displaying it?

I think it’s because the RASA has only one reflection so the image gets flipped relative to the refractor (no reflections)
