8" - 13.1" Optimized 6 Point Flotation |
Each
AstroGoods mirror cell is individually designed with support
points optimized to its buyer's mirror specifications.
This provides best support for minimizing stresses in
the glass that degrade performance.
A specialized image sharpening method is available, eliminating
mirror clip overhang with a Mirror Mask laminate
ring supported above the mirror inset into the inner edge
of the side supports. This: 1) Provides
a retainer too small for the mirror to unintentionally
come out.
2) Masks turned down edges (TDE) noticeably sharpening
the image. 3) Eliminates
diffraction replacing intrusions of mirror clips over
the mirror's surface with an uninterrupted sharp perfect
circle.
Adds $20 added at time of shipping, Select this option

 What
Specifications We Need: After placing an order you will
be transferred to this dimensions
form for: primary mirror diameter, thickness, focal
length or ratio and secondary mirror size.
What To Expect: the mirror cell it will provide 1/8"
space above the supports, 1/8" under the mirror clips
overhang and 1/8" between the side of the mirror and
inside face of mirror clips. This allows adding adhesive
backed felt pads for a precise fit without pinching the
mirror or allowing it movement in the cell.
For cells to be mounted in oversized tubes we may add $20. |
