Theoretically. Is it possible to construct a telescope using
holographic lens such that you flick a switch and the lens
just formed at the front. I like the idea of a very lightweight
0 wave error 6" refractor that I can carry at my back when
hiking and just putting it on the equally lightweight image
stabilizer mount when the sky has a great view.

In 4000 A.D. Can the above occur.. theoretically??

I can't see holographic equipment being very portable at first. Even
when it is, I'm sure it will be easier to simply GO within a few dozen
light years of the Great Orion Nebula and get a real view or take up a
nice spot on Ganymede on the sub-Jovian side at night and watch the
GRS spin or use 10x50 binoculars to watch the latest Pele eruption on
Io. Guess we'll still need telescopes to see galaxies though. :-)

Later generation light intensifiers and liquid mirrors are likelier to
make amateur astronomy more enjoyable before the advent or portable or
amateur holography equipment.
