Extensive optical test reports

[DavidU (Dave)]

Wolfgang Rohr has done many professional optical test reports on all types of telescopes and mirrors. It's translated from German.Interesting that some of the Skywatcher telescope systems are of a high standard.
This really puts facts infront of opinions.
It's a great read when the weather is bad.

That's a great resource to use in conjunction with other reviews. It's nice to know what you're really buying when the term 'apo' is slapped on just about ahything these days.

I'll be interested to see what he finds with the Synta 110mm f/7 ED triplet rumoured to be out soon.
