THIS TELESCOPE HAS BEEN PRODUCED TO PRECISE SPECIFICATIONS.

PRIOR TO USING  YOUR NEW GALILEO TELESCOPE, PLEASE READ THE FOLLOWING SETUP
AND USAGE INSTRUCTIONS. IT IS IMPORTANT TO PROPERLY ASSEMBLE YOUR TELESCOPE
IN ORDER TO ALLOW IT TO FUNCTION PROPERLY.

USE THE TELESCOPE FOR TERRESTRIAL (LAND) VIEWING  BEFORE  ATTEMPTING  TO VIEW  
ASTRONOMICAL  OBJECTS.  THIS  WILL   FAMILIARIZE YOU  WITH   HOW   POWERFUL EACH 
EYEPIECE   WILL  BE,  AS   WELL   AS   INTRODUCE  YOU  TO  THE   FUNCTIONS   OF  YOUR 
ACCESSORY  LENSES.

THE   IMAGE  YOU  SEE  WILL  BE  UPSIDE   DOWN   AND  BACKWARD. THIS IS  DUE  TO  THE  
FACT   THAT    YOUR   TELESCOPE    IS   AN  ASTRONOMICAL  TELESCOPE AND  HAS   BEEN  
MANUFACTURED   FOR    ASTRONOMICAL   OBSERVATIONS.   IN ASTRONOMICAL   VIEWING, 
THERE  IS  NO  UP OR DOWN, NO RIGHT OR LEFT.

WE  RECOMMEND  YOU  BEGIN  WITH  THE LOWEST  POWER EYEPIECE, 25MM WHEN USING 
 
HIGHER,  BUT   THE  IMAGE  WILL  APPEAR DARKER. THIS IS DUE  TO  THE BASIC  PHYSICAL 
PROPERTIES  OF  THE  TELESCOPE. THE  HIGHER THE POWER YOU USE, THE DARKER THE 
IMAGE WILL APPEAR AND YOUR VIEWING FIELD WILL BE MORE NARROW.

PLEASE BE PATIENT WHEN USING YOUR TELESCOPE. IT IS A VERY SENSITIVE INSTRUMENT 
THAT IS  CAPABLE  OF  USING  HIGH  POWER. HOWEVER, THE MORE POWER YOU USE, THE 
MORE  SENSITIVE  THE  TELESCOPE  BECOMES. AS  A RESULT THE SLIGHTEST MOVEMENT 
OF   THE   TELESCOPE  COULD  CAUSE  YOU  TO   LOSE  THE  IMAGE  YOU  HAVE  IN   YOUR 
EYEPIECE. PRACTICE  WILL  ENABLE  YOU  TO  KNOW  HOW  MUCH MOVEMENT TO EXPECT 
WITH EACH EYEPIECE AND IT'S CORRESPONDING POWER.
