Mirror support cell
In
Overview
Basic cells
A basic mirror cell can be built using minimal calculation and simple materials.[1] Only slightly more complex are the wooden, plastic or metal cells which are often glued and which are either not user adjustable or which have only limited adjustment and which are used in lower end commercial telescopes and smaller amateur-built telescopes.
Cells for more sophisticated "small" telescopes
Telescope makers seeking to build larger "small" telescopes with thinner mirrors find simple designs inadequate so they must resort to more complex design methods which include possible use of multiaxis adjustment potential and floating
There remains a good deal of discussion in the amateur telescope making community over the use of glue and the addition of simple astatic devices in such cells.Cells for large telescopes
Astronomical observatories require a much heavier and more complex mirror support cell. One notable example of the structure needed for such telescopes is the dual cell for the M1 mirrors of the 8.4 meter
