Roy,
I am not sure I can agree with your sweeping statement!
What specific astrographs did you look through ?
Was this reflectors with large obstructions or refractors ?
What eyepieces did you use ?
What were the problems ?
An FSQ106 is a well renowned astrograph and makes a truly superb visual scope as well. It doesnt just do it well, it does it exceedingly well and even better than some Apochromatics due to its colour correction, high strehl ratio, baffling . . . which gives it great colour and contrast.
I have used one many times and also for some public viewing nights - it was stunning to look through and would have put most achromats to shame, especially on lunar viewing.
Sean,
What is your budget ?
Obviously most astrographs are usually higher quality and fully corrected so they tend to be more expensive.
Also did you have in mind a reflector or a refractor ?
Cheers
Rally

Most of the different scopes do something better than another type. No scope is truly a all rounder for everything.
What are you mainly planning to do with it?
What else do you want to do withit?
