...Is it possible to construct a telescope using
holographic lens such that you flick a switch and the lens
just formed at the front...


William McHale:
You have been watching too much Star Trek . Theoretically I see no way
a "holographic" telescope could work. Light can't impact the path of light.


There are ways that theoretically one could bend light without a physical
lens; but they would involve manipulating the fabric of space time .


A gravitational-lens telescope?

"An entire amateur astronomy club disappeared from the known universe
as one of its members brought a gravitational-lens telescope to a star
party and club members who gathered around to have a look were sucked
into the black hole that comprised the telescope's 'lens.' An onlooker
who was sufficiently distant from the telescope to avoid the
instrument's event horizon reported that she heard a chorus of voices
shout 'Wow, what a view!' before the group 'simply disappeared.' The
Department of Homeland Security is investigating whether the group had
ties to Al-Qa'eda. Congressional Republicans are calling for a ban on
amateur astronomy, but the effort is not expected to go anywhere, as an
NRA spokesman says that the group opposes regulation of anything that
could be mistaken for a rocket launcher."
