■Relationship between eyepiece focal length and magnification
It is calculated by the formula: Magnification = focal length of objective lens (mirror) ÷ focal length of eyepiece. Also, since the focal length of a telescope's objective lens cannot be changed, all magnification adjustments are made by replacing the eyepiece.
As you can see from the above formula, the longer the focal length of the eyepiece, the lower the magnification, and the shorter the focal length of the eyepiece, the higher the magnification. The lower the magnification, the wider and brighter the visible area, and the higher the magnification, the narrower and darker the visible area.
During actual observation, stars are observed at the optimal magnification by changing eyepieces with different focal lengths depending on the object being viewed.
