There is one (maker unknown) within the Fugger Collection at Augsburg, barely 1" in diameter and 6" in focal length, that was concealed in a walking stick! Eyepiece lenses of 1/6" or much less in focal length had been fairly frequent.
The focal length of the telescope is representative of either the physical 'length' of the telescope, or its optical configuration. A short focal length will give a wide field of view (the region of night sky that will be observed), using the objects in that field of view appearing smaller, whereas a long focal length will give a narrow field of view, but using the objects appearing bigger. The magnification of the telescope may be the result of a combination of the focal length of the telescope itself, and focal length of the telescope eyepiece. A telescope of a specific focal length will create an image of a particular size, which is fixed and won't vary. The eyepiece, successfully utilized as a microscope, then views that image. A bigger image to start with allows the eyepiece to create a greater magnification. So, by altering the eyepiece, the magnification of the telescope may also be changed.
