Hey all,
If you don't care about D&G refractors, please don't post in the thread about them.
Let the discussion continue....
Thanks!

Thank you so very much. It was kind of a thread killer wasn't it.
Without saying anything more I'll just post this picture and let the discussion continue.

I guess actually I should say I know the young woman who owns it and her father who built it for her.

The only part I regret in the purchase of my new 8" f/12 is that I did not get to go to PA. and pick it up myself. That would have made it 100% perfect.
I'll wish you luck with your plans.

Steve, Bluestar, has more D&G's than you and even a F/15. What do you think, 10" F/12?

Nope! I'm thinking about an 11" f/15.
I can't get it off my mind.

You did a great job with your 100mm Carton Anil, I am sure you can as well with a 6" lens.

Ah D&G... my retirement scope for West Virginia in a backyard observatory.
Yes, a 12" f/12 would do me quite right. Wife approved ( ) after she saw a 12" tube assembly (less optics) in Barry's garage heading for California I believe.

Hi Ziggy
My current refractors the ES 6" f/6.5 (see the new review), and of course the APM 8" f/9 suit me quite well. The eyepiece images in both scopes are excellent. For the overall optical quality is very very good, in particular the APM.
As I have mentioned before, a club member and observing partner owns the APM 7" f/6. This scope provides wonderful images even at 300x plus, showing the overall optical quality is very good. If one needs to be convinced, he may take it at Cherry Springs in the spring with his new 22" dob.
Mounting and size of the observatory is another factor. Need room for the 22" dob and the 8" refractor.
So for me if the optical quality is very good (which D&G does have), then a 12" f/12 is perfectly fine for the very dark skies of West Virginia.

Plus Karl is old and older eyes are less sensitive to blue.
