Well for starters there are 2 glass surfaces in the elation that are polished to better than 100th of a wave , and set at something like 1.25 microns + or - 100th of a wave (that's 100th of one millionth of a millimeter ) apart perfectly parallel to one another in 2 dimensions , perfectly reflective thus bouncing the solar light back between each other at 300,000 Km/second , too zoom in on Ha light's frequency ,,, WOAW !, then there is the BF ( blocking filter) , OTA , focuser etc .
These have to be perfect or people loose their eyesight as you are looking at a magnified image of the sun ,,, ouch .
.
And safety aint cheep when this is concerned , sorry to say .
Yep us humans are quite smart in some ways .
