Dream Astrograph - 24" custom cellular primary, designed by Dream Telescopes & Accessories, Inc.

To the left is a CAD rendering of the 24" f3.5 that will have an outer physical diameter of 24.75", a usable optical diameter of 24.0" and is 3.625" deep (at outer edge).


UPDATE 8/15/07: The long-awaited first 24" cellular primary has been cast and came out of the furnace. Click below.

 


The finished mirror will weigh 35.0 lbs. A solid optic of the same dimensions and focal ratio would weigh 129.5 lbs.


Dream is combining the benefits of aerospace composites (specifically those that employ high modulus carbon fiber skins over a sandwich core) in the telescope structure with all-cellular mirrors.

Such telescopes require lower payload mounts. Mounts that are substantially less expensive in: initial cost, shipping cost, installation costs, maintenance, etc.. The 24" Dream Astrograph, for example, can be carried by the Paramount ME German Equatorial Mount. 

The thermal benefits of lighter, stiffer systems are enormous.
