Joe L's advise is accurate and correct. The maximum magnification of this telescope based on the 70mm objective lens is 140X magnification, however I received this for christmas from my wife and you most likely won't get close to that without some major work to the telescope itself. For one, mine had a very loose and sloppy focuser assembly, the threads and mounts were incorrectly drilled and tapped for the "finder scope", and the "finder scope" is of appalling quality (it's focuser is so sloppy that there is no hope to use it). As usual, the eyepieces supplied are not much better than the one's Galileo made back in the 17th century. Trash would be kind. HOWEVER, it does have a good objective lens (Acromatic doublet, air spaced) and it's not bad for colour correction. It's short focal length does hamper high magnification views, but keep it under 100X and it does well. My 2¢ here: shim up the focuser so it's nice and snug, but it still had good movement, buy some better quality eyepieces, and it will give very good views of the moon. With some additional tweaking and careful alignment, Jupiter and the 4 Galilean moons will be visible. Saturn will be a bit of a long shot. It's also worth mentioning that 1.25" focuser assemblies are available that will fit the optical assembly and with the 1.25" format, the quality of the eyepieces will be much easily obtained.
Put the eyepiece with the largest number written on it into the telescope. DO NOT USE the 2x barlow if you have one. This will double the power of the eyepiece. Your scope is too small to use the 2x barlow.
Now go outside during the day time and practice focusing on a distant object.

This is a small 70mm refractor style telescope.
