These revolutionary telescopes come standard
with all of the following: |
|
* For the last 15 years, the highest use
of carbon fiber
and CF skinned Sandwich Core (CFSC) of any company in the world. |
|
***- 95%
of the structure weight
is carbon fiber with only 5% traditional
metals. |
|
***- These
athermal telescopes use Dream's in-house carbon fiber extensively,
especially for the all-important mirror mounts. |
|
***- The highest stiffness,
lowest mass structures & telescopes on the market, producing
cutting-edge all-sky performance.* |
|
***- While
other companies say "carbon fiber telescope," most
use only 5-10% CF and 90-95% high CTE, inexpensive aluminum. |
|
******True
performance doesn't require constant refocusing to compensate
for low stiffness and non-athermal losses. |
|
* FAST™: Dream's Filtered
Air System Technology. |
|
***- Equalizes
the mirrors and interior air volume, while also keeping optical
surfaces clean for extended periods of time. |
|
***- Maintains
higher reflectivity longer, requiring fewer cleanings & extending
the useful life of coatings. |
|
* Dream's low-profile, precision actuator-driven motorized M2:
1.5µ/step without microstepping. |
|
***- Wide
footprint precision bearings & actuator's low-profile produce
a shorter, stiffer assembly & telescope length. |
|
***- Actuator
stalls at 95 pounds of force, for extreme stiffness. M2 on the
40" f8 Dream R-C weighs less than 7 pounds. |
|
***- Others use the same old, inexpensive
design from 50 years ago; a small diameter shaft that lack stiffness. |
|
* Intelligent modern designs, implementation
and technologies that provide truly cutting-edge total
performance. |
|
* Policies & Warranty. |

Performance Doesn't
Fear Change. It Defies The Status Quo.™ |
|
|
If the above 60mm
field Ø is too large or small, Dream can modify an existing
design to optimize it, including corrective optics. |

"Thanks for the manual.
I think it is the best treatment of focusing and collimation
I have seen. Very practical and real world. Your descriptions
include every small step and never assume the reader knows any
of them. It's not often that I see a manual this good." |
