Here is a 1975 Coulter mirror cell to fit a 12 1/2 inch telescope mirror. It takes a full thickness mirror. The mirror I had in it was 2 inches thick and fit perfectly. This is a 9 point flotation mirror cell, to help align the mirrors better. The cell fits a tube of 14 3/4 inched ID, interior diameter. 3 clips hold the mirror in place.
I have listed several items separately that came from my 12 1/2 inch telescope. If you want to purchase them all, so you can make your own telescope, contact me first. I will give you a small discount plus you can save on shipping.
SOLD AS IS!!! NO REFUNDS OR RETURNS!!!
