How to work out magnification level

• all lenses have a number stamped on them, with an 'X'
• the 'X' stands for the magnifying power of the lens -
  how much bigger it makes the object SEEM to be
• each lens magnifies the image from the previous lens...

To calculate:
Note the magnification power on the eyepiece lens
Note the magnification power on the objective lens
Multiply them together

Use Formula:
TOTAL POWER = EYEPIECE POWER x OBJECTIVE POWER
