The magnification is correct. The important measurement is arcsec/pixel
This depends on the focal length of the scope (not the diameter) and the size of the pixel. Maximum resolution of a lens does depend on the diameter of the lens.
Big scopes have better resolution (with some other factors also coming into play) allowing more "magnification" ie using a longer focal length or smaller pixels. (same effect)
