This 9" ellipse is 1.8" deep.
The first article for this design was engineered and cast
within five weeks of the initial order. Depending on existing
orders additional units around this size range can be produced
in as little as 15 days. An additional unit is currently available
for purchase.
One of these ellipses will be used with Dream's 28.5"
(physical OD) engineered cellular primary for a f3.3 astrograph
using a 4" corrector and large CCD chip. |
