Shown to the right are six triangular segments that
make up one 18-point floating cell. |
|
Each segment to the right weighs ~37 grams. The weight
of each segment is within 1% of any other segment. A testament
to Dream's consistency in fabrication. |

All hardware is Stainless Steel. |
|
Stainless is stiffer than aluminum and has a lower
CTE. |
Stainless obviously is preferred over common steel
because of its corrosion resistance. |
|
Stainless steel hardware is roughly four times more
expensive than steel. Dream is producing world-class instruments
and will not cut corners. |

The two photos to the right show enough floating cell
triangles for three 16" f3.75 Dream Astrographs. |
