"I went
to bed at about 10PM and I let it run all night without focusing.
I blinked through the images and focus did not
change. Also, I did all of my other images by letting it run
through the night without focusing." 1m prime focus telescope, aerospace

* Extensive use of Dream's
carbon fiber & CFSC™. Designed & fabricated in-house. |
|
***- The highest
stiffness, lowest mass structures on the market. Research Grade Telescopes, Research
Grade Telescopes, Research Grade Telescopes |
|
***- While
other companies purchase carbon fiber from outside vendors they
have no control over, Dream |
|
******does
all advanced composite work in house. Other companies claim a
telescope is "carbon fiber" but only |
|
******use
5-10% CF and 90-95% inexpensive, high Coefficient of Thermal
Expansion (CTE) aluminum. |
|
******Dream
does all CF & CFSC™ work in house & 95% of the structure
weight (everything except
the optics) |
|
******is carbon
fiber and only 5% are traditional metals. More CF & CFSC™
means superior
performance. |
|
***- Backplates,
mirror mounts, tubes, etc., are Dream's engineered CF & CFSC™,
which produce athermal |
|
******telescope
performance - no focus shifts over at least a 20°F delta
(change)
in ambient temperature. |
|
***- Because
Dream's mirror mounts closely match the Coefficient of Thermal
Expansion (CTE) of the |
|
******zeroDELTA™ lightweight mirrors, the optical
surfaces maintain their shape as temperature changes. |
|
***- High
temperature epoxy is used in all parts, vacuum-bagged and baked
in one of Dream's ovens. |
|
***- Materials
are chosen to eliminate focus shift during temperature changes. |
|
***- Materials
and fiber orientations are designed to minimize displacement
& mass. |
|
|
* Includes FAST™: Filtered
Air System Technology. |
|
***- Equalizes the mirrors and interior. Research Grade
Telescopes, Officiano Stellare Italy, Space Surveillance Network
(SSN), ASA telescopes, NASA, JPL |
|
***- Keeps optics and interior clean
for extended periods of time. |
|
***- Maintains higher reflectivity
longer, requires fewer cleanings and therefore extends life of
coating. |
|
* Focus is provided via Dream's precision
linear actuators, which are ASCOM-compliant. |
|
* 4" coma corrector with extended back focus; ~82mm. Hypergraphs
come with 90mm of back focus. |
|
* Includes a 3-piece collimation kit, protective
case & detailed instructions for optical alignment. |
|
* Real-world full testing
is done under the stars with each telescope, BEFORE they ship
to customers. |
|
***TThis page shows the all-sky performance
of a 16" f3.75 Dream Astrograph. |
|
* Each telescope has the highest all-sky
mechanical stiffness & total performance on the market. |
|
* Focal plane optical quality: if you are collimated and focused,
you will never be optics-limited. |

Dream has unrivaled installed
performance. The optical systems
won't
loose that performance as temperature, instrument angle or
even when more than a
decade ticks by! By design these are the highest performing
instruments in the world. |

"Thanks for the (Dream Astrograph) manual. I think it's the best treatment
of focusing and collimation I've 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." -*Dreamecustomer8888888 |
