For the price I dont think one can complain even if they got ED performance.

My Vixen ed115s is an ed doublet and according to
these pics .....
posted here its clearly bests the 127mm scope in question for CA and yet finding an interested buyer was asking the impossible
Goes to show that a quality well designed doublet easily beats a lesser triplet

I was able to do some direct "A-B" comparisons with my excellent Orion 120mm ED, and the AT matched or bettered its performance in almost all categories except color correction.

It would appear that triplet vs doublet doesn't automatically mean better colour performance.

The Orion has slightly better color correction and better "snap to focus," but the AT has better resolving power and brighter images.

So it matched or bettered the Orion? It would appear only those virtues expected with a greater aperture. Lesser "snap to focus" would concern me. My impression after reading the CN thread is that you are getting a Chinese scope with Chinese quality optics at a budget price. It sounds like reasonable
value for money, but a Vixen, tak, or even Orion it aint.
