answ2. Telescopes come in two flavours, reflecting and refracting.
Reflecting telescopes rely on the light first meeting a mirrored reflector which may be of large area, then passes through various focusing lenses.
Refracting telescopes have the light passing through a lens, before meeting the focusing lenses etc.
Now, there is a loss of light each time the light passes into or out of a glass, even ignoring imperfections of the surface. And more when that is considered.
And it is more than doubly difficult to make a large lens than a large mirror.
And since astronomy is mainly limited by the light-gathering power, this is vital to astronomers.
A1. Nothing. Any device to see the light of distant stars or other objects would still be called a telescope.
