I will have the mirrors recoated, purchase a new tube, and build a new primary mirror cell
and secondary mirror holder.
For example, Jason made Adrian's mirror cell
out of steel to the KB design.
My own use of the telescope has led me to conclude that it isn't the solid tube but the thick, solid mirror cell
in the back that was the problem.
Other clever ATMs will find even more ingenious ways to utilize these concepts to create new mirror cells
As such, the front ring and rear mirror cell
can be attached to the struts with socket-head cap screws.
A smart-designed mirror cell
(that's what computers are for) lets you use a relatively thin, lightweight mirror without compromising optical performance--thereby making the whole telescope lighter and reducing its cool-down time.
The fact that the scope is short enough for you to look in the focuser while adjusting the collimating screws on the mirror cell
is one more benefit of the 6-inch f/5 optics.
The mirror cell
was part of a reflector Porter designed in 1914 that allowed him to observe the sky through a fixed eye-piece in his warm parlor during the bitter Maine winters.
Superb optics Classic good looks Well-ventilated mirror cell
They also showed that specific subsets of mirror cells
increased their activity during the execution of an action but decreased their activity when an action was only being observed.
These neurons and another group located elsewhere in the premotor cortex have been dubbed mirror cells
For example, if you see someone showing disgust, mirror cells
in your own "disgust" brain module are activated, giving you a faint feeling of disgust yourself.
