Amen to that!!
I amazed this old chestnut still comes up.
In an ideal world , the ratio is "about" 7:5 ....i.e a perfectly made 7" reflector gives very similar images to a perfectly made 5" APO.
But don't expect "perfect optics" at bargain basement prices.
It is 2x as hard to make reflective optics as good as refractive ones (physical optics 101
)....hence optical quality is often confused with quantity.
Rest assured you will be *very* happy with and AP160 or Sutching 200mm Parabola...the design is very much secondary to the execution.
