This is very important to every astronomers but easy to learn. Calculating the magnification always helps you to know the current situation and get the best view of the objects. For every celestial objects, there are always the most suitable views (magnification) for it. Let’s back to the topic, I shall discuss the most suitable views in the coming days.
The formula is very easy.
Magnificaiton= Fo / Fe
Fo: Focal length of telescope
Fe: Focal length of eyepiece
Let’ say, I am now using a f=2000mm telescope with f=26mm eyepiece. The magnification value will be 2000mm/26mm= 77X. Therefore, I am now having a 77X magnification.
