How to calculate the telescope magnification (example): 
If the longest lens (45 mm) is used, then multiplying its increase by increasing the eyepiece (10x), we obtain a total magnification of 450 times, i.e. the object will be enlarged 450 times. and with an increase in the eyepiece in 20x we get an increase in the observed drug in 900x
