The eyepiece will have a shorter focal length than the objective lens has.
The focal length of a telescope is directly related to the magnification in that the longer the focal length, the more magnification you get from the telsceope. How the focal length of a telescope relates to the length of the telescope itself depends on the design of the telescope. In a refracting telescope, the focal length is approximately the length of the telescope. In a reflecting telescope, the focal length is roughly two time the length of the telescope.
Technically the shorter the focal length, the thicker the mirror. But some short focal length telescopes have relatively thin mirrors all the same.
The focal length of the telescope's mirror can be calculated using the formula: Telescope focal length = Eyepiece focal length × Magnification = 26 mm × 70x = 1820 mm Therefore, the focal length of the telescope's mirror would be 1820 mm.
The magnification of a telescope is calculated by dividing the focal length of the telescope by the focal length of the eyepiece. In this case, the magnification would be 3000 mm (telescope focal length) divided by 15 mm (eyepiece focal length), which equals a magnification of 200x.
The magnifying power of a telescope is the focal length of the scope in millimeters, divided by the focal length of the eyepiece in millimeters. Focal length of scope: 225cm=2250mm Focal length of eyepiece: 7.5mm 2250/7.5= 300X

The distance between the two lenses of a refracting telescope depends on its design and purpose. Typically, the lenses are separated by a distance equal to the sum of their focal lengths. This separation allows the lenses to work together to focus light and form an image.
The relationship between focal length and angle of view is such that the shorter the focal length, the wider the angle of view. Shorter focal lengths encompass more of the scene in the frame, leading to a wider angle of view.
The magnification of the telescope image is(focal length of the objective) divided by (focal length of the eyepiece).The focal length of the objective is fixed.Decreasing the focal length of the eyepiece increases the magnification of the image.(But it also makes the image dimmer.)
The formula for calculating the angular magnification of a telescope is: Magnification focal length of the objective lens / focal length of the eyepiece.

The magnification, or power, at which a telescope is operating is a function of the focal length of the telescope's main (objective) lens (or primary mirror) and the focal length of the eyepiece employed.
The apparent magnification of telescope optics is(focal length of the objective) / (focal length of the eyepiece)= (1,000 / 25) = 40 .The diameter of the primary mirror has no effect on the apparent magnification.The length of the body tube is involved in the case of the Newtonian configuration,only because it has to be long enough to hold the eyepiece in the right place.
