I will be very suprised to see a 6" APO for less than 2K.
Not new instruments, but A-Mart has had some very lightly used offerings.
Saw a Meade 152ED OTA listed for $1900 about a year ago.
A couple more have been advertised for $2000.

There was a 4in Meade for just over 500, and the seller was throwing in shipping. Man if I had the cash right now.....

I noticed one of those ads and was tempted. I read all the reviews I could find about the Meade 152 ED and although many were rating it highly, some weren't happy with it. In the end, I just couldn't pull the trigger.

I almost bought a 5" D&G last year. Ultimately I determined that such a refractor was best suited to a permanent installation. If I ever build that observatory, I'd like to have one of them.

Peter,
A 5" f/12 or the limited production f/10 might be portable.

Yeah Scott, even the F12 5" was too big. That's funny coming from someone with a dob that's eleven feet tall. I called Barry and asked about an F10. He hasn't made any of them in about 3 years, and has no plans for another run.

Dang - thought I found a solution for you.
How many folks own 6" D&G's on Cloudy Nights?

All,
I agree with you, Tom's review is well written. I think the violet fringe I see in mine is more bothersome to me that it is to him; however, I only see the fringe on "unfair" objects like Sirius, Vega and Venus. It's there on the lunar limb, too, but so thin it isn't objectionable to me. On the other umpteen objects to see in the sky, the view is fabulous. I've seen the Enke minimum (from an urban location), the Great Red Spot, the dust lane in M104 and the spiral arms in M51. I've split 1.2" doubles (magnitude differences less than 4 magnitudes). All that was last winter and spring. I can't wait to see what the D&G will show me this summer.
To answer questions about mounts: I use mine on a G-11 without the pier extension. I sit on the ground to observe with my scope. Damping time after the scope is disturbed in 1- 2 seconds. After that, with no wind, the scope is rock steady. The man I bought it from used an Atlas and was happy with it. Last summer I'd get +/- 10 arc minute pointing accuracy. I have good luck with breezes up to 5 mph, but don't like the shakes I get when the breeze it stronger than that.
My experience tells me that D&G makes top notch refractors. The man who sold mine to me said the same thing: it took a Tak to make him part with his D&G.

The review hits the nail squarely and truthfully on the head.
I had a thin yellow line on the lunar limb in my wonderful and highly-regarded Tak doublet FS-102, really a semi apo by current standards...and I too don't spend much time starring at Vega or Sirius but concern myself more with the 99% of objects that don't exhibit CA to worry 'bout the miniscule amount of CA in the D&G...on deep sky as well as planets I concentrate more on the detail and alarming contrast. Apo triplets, doublets (I've been blessed to have owned and used the BEST) and now high-quality achromats...D&G is the "Astro-Physics of achromats" (after Barry's lenses being recommended by AP's Roland Christen) and the ONLY one I would consider purchasing for my critical and demanding personality.
I owned the D&G 5" f/12 (purchased used), regretfully sold it in favor of the upgraded 6" f/15. Now I'm ordering the 8" f/12 and reordering a new 5" f/12 as the "portable D&G". Call me a devotee, achro-nut...all I know is what I like, refractors aren't renowned for their "refractor-like views" for nothing and the D&G line is a winner at BlueStar giving me the most for a ridiculous price...thanks to Barry's hands-on passion for optics and the stargazing community.
