D&G 6" Refractor?

Can anyone with a 6" D&G offer an opinion? Build quality, optical performance, etc etc.....I was thinking about an F12 tube assembly. With the exception of the occasional D&G that shows up in the Astromart classifieds I havent found too much in the way of user feedback on this scope.

Thanks,

Hi Tom,

It's been a while but I worked on a couple of them. As I remember, just cleaning, collimation, focuser issue and a large pier mount that swayed light the Golden Gate in a storm.
They were "OK", no serious optical issues for a doublet. But that means plenty of chromatic aberation and some spherical error. In reality, any 6" newt of average quality would out perform it in all categories. Both scopes were 6" and had the same views.

Two scopes don't represent a solid sampling, so maybe someone else will chime in here!

Thanks,
John

Hi Joseph,

Just out of curiousity, what height pier did you use and which mount? I have my 8" D&G F/12 on a Parallax HD 150 and a 60" tall 10" diameter pier. Wonderful scope!
