Aperture  :   70mm
  **The diameter of the hole or an opening through which light travels. The bigger the aperture, the more you will be able to see.    
Focal Length  :   400mm
  **The focal length of a telescope measures how strongly the system focuses or defocuses light. Usually a longer focal length is associated with larger magnification of objects (aka narrower angle of view), while a shorter focal length is associated with a wider angle of view.     
Focal Ratio  :   f/5.7
  **Focal ratio is calculated by dividing the focal length by the aperature diameter. The focal ratio determines brightness/light gathering power. High focal ratio is necessary to view planets.
