Customer comments
Every AstroGoods standard mirror cell is custom designed and
optimized. Optimization minimizes stresses which may distort
the mirror and degrade the image.
Proper calculated mirror support positions produce the sharpest
images.
6" mirror cells have felt pads at the three support positions.
Mirrors 8"-13.1" have six-point support. All support
points are calculated for the mirror's diameter, thickness,
focal length and secondary mirror size. We size fit to the
inside diameter of your tube. We cut our retaining mirror
clips to be 1/8" above the front surface, securely containing
it in the cell. Kits arrive rough sanded with all parts. You
fine sand, paint wood parts. Assembly is easy. Finished cells
arrive painted, assembled and ready to use.
