Re 120 ED quality - my Orion Epoch 120 ED F7.5 shows a perfect star test and no false colour , I doubt a very high end APO will show a significant improvement on that to justify 2 or 3 times the expenditure.

Hopefully this isn't speculation and based on actual observations with top end TVs, APs and Taks.
I think it best to simply conclude that we agree to disagree. I have lost count how many cheap and expensive refractors I have personally compared over the years but if money isn't an issue I know which are, from my actual observatons, better.
I just can't comprehend how so many people (including myself) around the world are apparently hoodwinked into wasting money buying high end refractors or how companies such as TV, AP and Tak can possibly stay in business if any of these mass produced Chinese scopes or Achros were anywhere as good.
Why would anyone bother spending almost 5k on a TSA-120 if a SW BD120 for approx. 2k was just as good
