Anything available on the internet is less than 20k. This is 50x better than a Walmart telescope.

I cited the spectrum.

Aluminum lenses are cheap and are transparent to x rays. And the ballon is cheap too, see googleadservices.com/pagead/…

I would like more specific objections, it doesn't seem that hard.

Will stack exchange observe my experiment?

Then amatuer balloonborne uv telesocpe for 20k.

You don't need x-rays. Just uv.

There are amateur x rays, balloons and telescopes, you just put them together.
