These revolutionary instruments come standard with all of the following:

Since 2003 Dream has produced instruments with the highest amount of carbon fiber & CF skinned Sandwich Core (CFSC™) of any company in the world.

***- 95% of the structure weight is carbon fiber with only 5% traditional metals. Make sure the instrument you're ******looking at from others is actually carbon fiber. Ask pointed questions and look closely at photos. Buyer beware.

***- These athermal instruments use Dream's in-house carbon fiber extensively, especially for the all-important mirror mounts.

***- The highest stiffness, lowest mass structures & instruments 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 & non-athermal losses.

******Knowledge is power. Ignorance a liability.™

Custom 20" f7.5 shown in the f5.6 focal reducer configuration. Telescope tube 44" long. Spider hub, vanes, inserts & hardware are stainless steel.

* Both M1 & M2 are Dream's zeroDELTA™ engineered lightweight mirrors.

***- Mirror seeing and tube currents are eliminated due to the mirrors' extremely short thermal time constant & FAST™.

***- 3-6 times lower mirror mass than traditional technology, producing far less flexure of mirror mounts and structures.

* 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: 1.5µm/step raw oerformance (before 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.

***- Old, inexpensive designs from 50 years ago that use a central, small diameter shaft, lack enough stiffness.

***- M2's have been finished to as high as L/125 RMS surface, with 2Å RMS surface roughness.

* Intelligent modern designs, implementation and technologies that provide truly cutting-edge total performance.

* Policies & Warranty.

If the above ~50mm field Ø is too large or small, Dream can modify an existing design, including corrective optics.
