Comments on: How does a camera lense work different from a telescope?

To summarise: a telescope is essentially 2 lenses placed one after the other.
The eyepiece is just a magnifying glass in its simplest form, more advanced ones may have multiple elements similar to a camera lens.
Either will work similarly to a camera lens (in fact you can fit a camera instead of the eyepiece of a telescope), together they provide the effect you see.

By changing out the eyepiece of the telescope you are essentially magnifying a magnification. The idea is still the same - a longer barrel on the telescope would increase magnification too - but for amateur equipment swapping out an eyepiece is cheaper to manufacture.

In a telescope where you can change the magnification it is a reflecting telescope and the eyepiece goes in the side. What you are actually doing is using a small telescope to look at a small part of the captured image and enlarge it for your eye - you are not changing the light capturing ability or enlargement of the over all telescope.
In a refracting telescope with the viewing on the end through lenses, you are using lenses the same way the camera does - adjusting the focal length and viewing the result.
