Interesting information for starting 
 

By  buying  a  telescope  you  made  the  decision  to  pursue  a  very  interesting  and  exciting  hobby  and  we 
congratulate you. We would like to give you a couple of tips upfront. 
Astronomy isn’t a cinema movie 
Astronomy  isn’t  a  cinema  movie  that  you  watch  for  a  couple  of  hours  without  doing  anything.  This  great 
hobby  needs  a  lot  of  self-initiative  and  a  high  self-motivation.  Take  your  time  for  this  beautiful  hobby, 
because, like with many other things, you have to practice the handling of a telescope, how to properly view 
things  with  it  and  the  orientation.    The  pictures  that  you’ll  see  are  also  not  the  ones  that  you’ve  seen  as 
colored  pictures  from  NASA  or  that  you  know  from  the  media.  So  don’t  be  disappointed  when  you’ll  get  to 
see how an object really looks like through your own telescope.  
Don’t expect too much at once and approach the topic slowly. You’ll only see as much as your experience 
and  your  ability  allow  you  to  see,  even  with  the  best  and  most  expensive  telescope.  The  journey  is  the 
destination  and  the  fascinating  thing  about  this  hobby  is  the  independent  discovery  of  the  objects  and  the 
analysis of time and space.  
Learning from others 
The exchange with other astronomers is an important factor and nowadays this can be easily done through 
the many Internet forums. By talking with like-minded people you can get tips and solve many problems and 
answer many questions yourself. Maybe you’re also looking for an astronomy club near you? 
There are countless objects in the sky that can be seen with a telescope. A map of the stars is essential, so 
that you’re able to orientate and find specific objects. You can find and purchase one that is robust and made 
of plastic on the Internet.  
It’s essential to buy an astronomy book that’s suitable for you and we recommend that you don’t eschew this 
purchase.  Our  experiences  have  shown  that  hobby  astronomers  get  better  observation  results  and  also 
derive a lot of joy from this hobby by using a book.   
Children should watch together with someone else, who is already experienced with a telescope, if possible.    
Not every location is suitable for observing 
It’s  best  to  look  for  a  spot  that  is  as  dark  as  possible.  You’re  lucky  if  you  live  outside  of  the  city.  The  ones 
living in the city should drive outside of it to get better observation conditions. Because it’s almost impossible 
to find a dark observation location in the city, due to the many light sources. 
Consider  that  the  temperature  of  the  telescope  has  to  adapt  to  the  outside  temperature  to  get  decent 
observation results. 
The underground is also determining the observation quality 
Avoid pulling out the tripod legs completely and erecting the tripod when it’s very windy, so that you have a 
proper footing.  The flatter the instrument is standing the more stable it is. 
Make sure that the tripod is standing on a firm ground. Balconies, wooden floors or other undergrounds can 
make observations more difficult, due to their high self-oscillation.  
Free sight for your telescope 
Don’t  observe  through  a  window  or  through  an  open  balcony  door,  because  the  temperature  differences 
between inside and outside and/or the thick window glass are making it impossible to get a sharp picture. 
 

How does a telescope actually work? 
 

A telescope collects the weak light of the stars better than a human eye is able to. Thus you can see more in 
the sky with it.  
Depending  on  the  kind  of  objective  you  distinguish  between  refracting  telescope  and  reflecting  telescope. 
Both have the same job; to capture the light of a distant object and accumulate it at the focal point, where the 
ocular will then magnify the image.  All telescopes create an image that is turned by a 180 degree angle; so 
it’s upside down and mirror-inverted  
 
Telescope designs 
The refracting telescope: 
You look into a refracting telescope at the rear end. They are also called refractors, because they break the 
light  (Latin  “fractere”=breaking).    The  light  falls  from  the  frontal  lens  onto  a  second  lens  and  from  there 
through an “ocular” into the eye.
