6" D&G with Chromacor?

How about a 6 inch f12 or f15 D&G with a Chromacor?

How should that perform?

Using the Chromacor, would the f15 have any advantage over the f12?

I'm having some very un-Shawn-like thoughts. On the other hand, Shawn
might appove, in comparison to a 6" Tak or AP in cost.

Doug,

Take a 6" F/12. It will be significantly more compact, easier for
Chromacor installation, require less heavy mount and easier to
install it.

The difference in performance will be better with F/12, because it
is closer to the designed F/8.

Hi Doug, I've never really heard any bad news about the D+G Scopes.
Optics supposedly are very smooth, and well figured, and assembled.
Should be considerably better than what Meade, and Celestron are
offering from China.

The only downside with the long FL Achromats is there long length, which
will place considerable torque load demands upon a lesser mount, even
though they are not all that heavy in weight.

Should Valery supply a correct Chromacorr combo suitable for the D+G, it
seems to be a very nice refractor set-up, at a reasonable cost.

Checking the D+G site not long ago, I see that D+G now uses an AP 2.7"
Focuser with thier Refractors. This is a tremendous plus. As we all
know, a good Telescope (Of any type) is very hindered, and miserable to
use, if the Focuser is poor, sloppy, and cannot achive good precise
focus repeatedly. The AP Unit will achieve this without a problem, and
should compliment the good D+G lens.
No Feathertouch 2-speed Option should be needed at either F-12, or F-15
with the AP 2.7". Mark

Valery,

Does that mean that an f8 Synta with a Chromacor would be better than
an f12 D&G with Chromacor?

Dough,

More or less equal. So, from practical point of view F/8 is better
(obvious advantages in length, portability, mount requirement).

However, D&G is well known as a company with excellent quality of
their scopes.

So, I can't give you a final answer. Here you can decide yourself.
I am quite satisfied with the results which Chromacor gives with
6" F/8 Celestron.

Doug,

The difference goes well beyond which ever is best mated to a
Chromacor. The most important aspect of any optic is the figure
and in the case of refractors, the homogenity and quality of anneal.
High quality lenses take time to squeeze the best wavefront out of
and the materials and craftmanship of the rest of a high quality OTA
make all the difference in all aspects of the observing experience.

Some individuals have gotten some very good optics out the Chinese
imports, but it seems to be inconsistant. D&G are consistantly
optically excellent the last I heard, and backed up with first rate
mechanical components.
