Portability. Think about it.
I have a 6" newt on EQ mount. But it was annoying trying to manouvre it outside, through 3 doors and up to 2 sets of steps. So got a 6" sct - very easy to handle.
Portability doesn't always mean for travelling away from the house. I didn't use the newt as much as I was using the sct.
Do you understand about how aperture size affects what you see?
