  • Page 4 OBJECTIVE lens focal length divided by EYEPIECE focal length = MAGNIFICATION (e.g. Using the 20 mm lens, a sample calculation could look like this: 750 mm / 20 = 38x or 38 power. Telescope models will vary in focal length.)
  • Page 5 Saturn, Mars, Jupiter, and Venus are good second steps to take. 2. The first thing you need to do after assembling the telescope as planned is center the desired object in the finderscope’s cross hairs. Provided you did a reasonable job aligning the finderscope, a quick look through the main telescope tube at low power should reveal the same image.
  • Page 6 This might come in very handy if the family dog has just bumped the telescope out of alignment. By using this mode you can center the telescope on any known object and select align object to quickly recalibrate the Northstar alignment allowing continued enjoyment for the duration of the evening.
  • Page 7 SELECT MODE ALIGN EARTH ][ This mode assumes that even if the telescope user is a first time user and does not know anything about astronomy that they can be successful aligning the telescope in a few simple steps. The ALIGN EARTH option is flashing.
  • Page 8 With just two more steps, you will zero in on pinpoint accuracy. Now the telescope will lead you through a simple two star alignment process. YOU DO NOT NEED TO KNOW WHERE ANY STARS ARE.
  • Page 9 This is a great educational tool !!!! To find the object, just press the “GO” button and that object will be right in the telescope’s eyepiece! By pressing the BACK button, you move back to the previous level each time the button is pressed. Press the button three times and you are back at the main level menu.
