2)  Loosen  the  large  knob  (8)  at  the  back  of  the  adaptor 

and put the smartphone on it with face up. 

 

3)  Adjust  the  position  of  the  horizontal  arm  (1)  to  fit  the 

width of the smartphone and tighten the large knob (8)

  Using STAR WALK

TM

 2 for Telescope

 

 

A  stargazing  smartphone  software  application  (e.g.  Star 
Walk ™ 2 for telescope for iOS and Android) helps you find 
and identify the celestial objects easily.  

Select  “Take  a  Tour”  (Menu 

 

  Take  a  tour)  to 

familiarize yourself with the various app features. 

The  App  language  will  follow  your  smartphone’s  language 
setting.

IDENTIFY THE CELESTIAL OBJECTS 

After the  smartphone adapter is  attached  to the  telescope, 
the  smartphone  orientation  is  aligned  with  the  telescope.  
Utilizing  the  smartphone’s  location  and  orientation,  a  star 
map application can show the real time simulated sky view 
on  the  screen  matching  the  view  through  the  telescope.  
Names of the stars or celestial objects are shown on screen 
and automatically updated when users adjust the telescope 
or move the telescope to a different location. 
 
 
 
 
 
 
 
 
 
 
 
 
 

 

 
 

SEARCH AND DIRECT 

Another advantage of using the application software is  that 
users  can  search  for  a  celestial  object.  The  screen  will 
guide users which direction to move the telescope. 

 

 

 

iii. 

Using The Smartphone Eyepiece Adapter 

 
The  smartphone  adapter  is  also  equipped  with  an  adapter 
to  attach  to  the  telescope  eyepiece  for  photo  and  video 
capture..  

 

 

 
1.

 

 To remove the adapter 

from the telescope, 
press the quick release 
lever (4) and slide the 
smartphone adaptor 
ou

t.

 

 

 

 

 

 
 
2.  Loosen the small 

screw (10) at the top. 
Attach the adaptor-
smartphone assembly 
to the telescope 
eyepiece as shown. 
The adaptor should be 
fully inserted into the 
eyepiece for best 
results. Tighten the 
small screw 

 
 
 
3.  With  the  camera  app  opened,  re-adjust  the 

smartphone  camera  position  by  slightly  loosening  the 
main  adaptor  screw  if  necessary.  The  image  circle 
should be at the centre of the screen. Adjust the focus 
knob until the image is clear.
