Hi Cristiano
A few years ago some friends and I had one of these scopes of yours side by side with my Astrophysics Starfire 6" APO and after observing several objects and comparing side by side those present all agreed that the views through the AP were indeed slightly superior but we were all surprised at how close it was considering the vast difference in price.
I think for deep sky astrophotography it may have some slight limitations but for visual I think you have a winner
