Dear Mr. Baader, I am happy to comply with your request and share with you my criteria that led to the purchase of the 17 inch telescope from Planewave, and following my experience with this telescope. Since this was a rather complex topic, please forgive the long text and its extent, which certainly clearly exceeds a "normal" customer judgment.
The full review of the 17" PlaneWave Astrograph by Mr. Paech can be found here :
To the last point, my following remark: I have not looked into the RC telecopes offered on the amateur market, which are delivered at 16 inches opening and a price below 10,000 euros. Production at this selling price - especially for an RC system - was unimaginable to me. In addition, it is hard to find any reference images taken with these instruments on the Internet, in comparison European - made RCs and PlaneWave telescopes have many international references.
