| This article has surprisingly little substance, given its title.

| They might as well have just said:

| _There are three large telescopes in the works in different
| parts of the world. Here 's a picture of one of them._

| So a typical _Next Generation_ article.

| Eric Berger has a frustratingly amateur perspective on his

| "New computers in development" when referring to
| supercomputers in China and the US. For someone who's spent
| so much time on these subjects, he never has more than a
| surface level understanding of anything related to aerospace
| or astronomy. Compare to a guy like Bill Sweetman who writes
| with extraordinary detail on aviation despite never being an
| engineer himself.

| a lens long enough to have the moon's size be impressive. Wide
| angle shots to establish location with the moon leaves the moon
| a tiny size in the image. Telephotos zoom in past the
| interesting scenery unless moved far enough away--the longer
| the lens the further away. My current plan is a big drone to
| support the lens but the location puts me closer to a highway
| than I'd like to fly a drone. Oh well, I can see it in my
| mind's eye

| catadiotropic lens.
