The first 24" cellular
primary has arrived at Dream. |
|
* Dream Astrograph's come equipped with a 3" Astrooptik
(Philipp Keller)
coma corrector and
4" electronic focuser.
The 4" focuser allows either the standard 3" coma corrector
or the 4" coma correctors, without the need to change the
focuser. The 3" coma corrector allows enough back focus
distance for both a camera and filter wheel. It will not work
with an AO-7, for multiple reasons. SBIG does not recommend AO
use below 100" of focal length. Upgrades include a standard
4" coma corrector or a custom
4" coma corrector as well as a 4"
Off-Axis-Guider. Custom
adaptors that place your imaging train at the correct back
focus distance can be ordered for your specific equipment. For
Paramount ME customers a new, large
dovetail is now available for the 16" Dream Astrograph. |
|
|
|
|
* A corrected 1.8x barlow that allows AO use (AO-L, for example
and/or off-axis guiding prior to filters) will also become available.

Why
a |
|
|
|
* These carbon fiber telescopes are ready for high
quality, corrected imaging. Custom alignment
tools and key design features, like a rotation on the secondary
mirror that allows independant adjustment, make collimation of
the optics a truly unique experience. Attach your CCD imaging
train to start enjoying these state of the art carbon fiber OTA's
and the ultimate in corrected
optics. Stainless steel hardware is used on all Dream telescopes.
The 16" Dream Astrograph is now being offered in a unique
tube version that does not require mounting rings. |
|
|
|
 |
* Dream's mirror cells, back plates, filter caps, etc., are made
of carbon fiber utilizing sandwich
core. The use of carbon fiber in the mirror cells especially
has unique advantages over metals. |
|
|
|
 |
* Composite materials (carbon fiber and sandwich core
technology) are fabricated in-house using vacuum
bagging, as well as other more complex techniques and equipment.
High temperature epoxies are used in all parts and cooked in
one of Dream's two ovens. Materials are chosen to minimize or
eliminate focus shift during temperture changes. Materials and
fiber orientations are designed to minimize flexure and mass. |
|
|
|
* Focal plane optical quality: if you are collimated, you will
never be optics-limited. Test documents are provided for both
mirrors. |
 |
* Exterior composite parts: gloss white. |
|
|
* Dream is an authorized distributor of Astrodon filters. Contact
Dream to learn why these specific filters match the Dream Astrographs. |
