Part II: Getting Started 

 

Aligning the finder scope 

The  8x50  finder  scope  is  a  small  fixed  magnification  scope  mounted  on  the  optical  tube. 
When it is correctly aligned with the telescope, objects can be quickly located and brought to 
the center of the field. 
 
The alignment should be done at first use and over time if the alignment is no more accurate. 

 

Alignment is best done outdoors in day light when it's easier to locate objects 

 

If it is necessary to refocus your finder scope, look at 
an object that is at least 500 meters (or yards) away. 
Loosen  the  knurled  ring  by  unscrewing  it  back 
towards  the  bracket.  The  front  lens  holder  can  now 
be turned in and out of focus. When focus is reached, 
lock it in position with the knurled ring

 (

When  the  finder  scope  is  in  focus,  choose  a  distant  object  that  is  at  least  500  meters  (or 
yards) away and point the main telescope at the object. Center the object in the eyepiece of 
the telescope by aiming precisely at the distant object. 

 
 
Now, check in the finder scope to see if that distant 
object is exactly positioned behind the crosshairs of 
the  finder  scope's  eyepiece.  If  not,  adjust  the 
alignment  of  the  finder  scope  with  the  two  black 
adjusting screws on the bracket of the finder scope 

(

)

Do  not  over  tighten  the  screws  when  aligning  the 
finder scope. 
 

 

The  image  in  the  finder  scope  is  upside-down.  This  is  normal  and  has  no 
incidence on observations.
