Using your telescope: 

This telescope is our best selling telescope and has been sold hundredfold 
worldwide. It even served as demonstration telescope on various astronomy 
events.  
 
Astronomy  is  a  great  hobby,  which  nevertheless  requires  a  certain 
knowledge about the topic.  
 
Do  not  try  and  use  your  telescope  by  aiming  through  a  window.  Take  it 
always  outside.  If  you  are  inside  and  the  window  is  closed,  glass  will 
introduce  reflections  und  distortions.  If  the  window  is  open  the  moving  air 
currents of different temperatures will cause distortions.  
 
Let  your  telescope  adjust  to  the  outside  temperature.  Your  telescope  will 
perform  much  better  if  the  lenses  and  the  air  inside  the  tube  are  all  the 
same temperature as the outside air. This process may take up to 1/2 hour 
if the temperature difference between inside and outside is extreme.  
Try  to  find  a  location  that  is  away  from  glaring  lights.    If  you  are  in  a  large 
town  or  city  you  may  want  to  try  and  find  location  in  the  country.  Using  a 
telescope in the skyglow of a town or city can cut its ability by half.
