How you arrange two convex lenses of focal lengths $5 \mathrm{cm}$ and $30 \mathrm{cm}$ to form an astronomical telescope?

If an astronomical telescope forms a clear image of a star, what will be the distance between the lenses?

Why is the aperture of the objective lens greater than that of the eyepiece in a telescope?

What change in the image will take place if half of the aperture of the objective lens in a telescope is covered by a sheet of opaque paper?

Which lens of an astronomical telescope forms a real image and which lens a virtual image?
