The magnification (or power) you will see through a given optical system depends on the telescope and the eyepiece. The simple formula is: Magnification = Focal length of telescope ÷ focal length of ...

Telescope focal length determines image magnification. Field of view (FOV) shows how much sky your telescope displays. FOV is calculated using telescope and camera/eyepiece specs. Match telescope FOV ...

Shini talks to us about optical instruments and how they make magnification possible. How do lenses work? How do they form images? Well, in order to understand how optics work, we have to understand ...

This article is the third in a series teaching the basics of photography. We started by learning about the properties of light and how an image is created, and we also learned how a lens bends light ...
