I agree. There are still some companies that do mirror "aluminizing" or
"resilvering" for telescope optics. They should be able to do sextant
mirrors which are comparable in size to the secondary mirrors in Newtonian
reflectors. You might try googling "telescope mirror resilvering" etc. Of
course, this is expensive. It may be cheaper to acquire sextant mirror
spares and then cut them to fit an older sextant.
The prices of high-quality commercial telescopes have declined dramatically
in the past twenty-five years so home-built telescopes,
and the cottage industries that supported them like mirror
resilvering, are becoming rarer. But, wow, you sure can get a great
telescope for a modest amount of money! Damn shame the stars have
disappeared...
