An astronomical telescope in normal adjustment receives light from a distant source `S`. The tube length is now decreased slightly

A virtual image of `S` will beformed at a finite distance.

No image will be formed.

a small, real image of `S` will be formed behind the eyepiece, close to it.

A large, real image of `S` will be formed behind the eyepeice, far away from it.
