What aperture of catadioptric telescope will give the same 'views' as a reflector?

What aperture of catadioptric telescope will give the same 'views' as a reflector?
I was planning on buying an 8/10" reflector, but realised I would probably need something more compact.
Do cat..s have to have the same aperture to give the same 'views' or will a smaller one do the same thing?
Thanks! :)

A catadioptric telescope is basically a combined lens/mirror system, the most common commercial example of which is the Schmidt-Cassegrain or Maksutov-Cassegrain designs. The lens, also known as a corrector plate, is the same size or larger than the primary mirror & is used to correct the light rays entering the telescope so that a cheaper & easier to manufacture spherical mirror can be used.

It will present essentially the same views as a Newtonian reflector of the same aperture, but with perhaps slightly less contrast as the secondary mirror obstruction is generally larger in the catadioptric designs. It's very doubtful that you'd ever notice the difference.
