Starscopes on azimuthal mount

1. How far can I see with my telescope?

That depends largely on how dark the sky is. 
From the city you can comfortably see the 
brightest planets (a few hundred million kilo-
meters). Beyond the solar system, because 
of the huge distances, we no longer calculate 
in kilometers, but in light years. One light year 
is nearly 10 trillion kilometers! With the naked 
eye you can see stars which are some light 
years to some hundred light years away. 

2. I see nothing when I look through my 
telescope, what am I doing wrong?

Observing through a telescope takes practi-
ce. Initially, you will notice detail only in the 
brightest objects. However, with each obser-
vation you will be able to see more detail and 
objects that were previously „invisible“ will 
suddenly become visible.
If you do not see anything at all, please check 
the following: 
• Is the dust cover completely removed? 
• Is the magnification too high? 
• Is the object in the field of view? 
If in doubt, point the telescope at an object 
that is easier to see to make sure there is no 
technical problem. 

3. the image becomes very dark when I 
choose a high magnification. Why?

The higher the magnification, the darker the 
image will be for geometric reasons. If you 
find the image too dark, simply choose an 
eyepiece with lower magnification (= longer 
focal length). 

4. The celestial objects move when I 
observe them through my telescope and 
disappear from the field of view. Why?

In truth, it is not the celestial objects that 
move, but it is our Earth itself that rotates 
on its own axis. Therefore, in 24 hours all 
celestial objects „wander“ once completely 
around the earth. With the naked eye this 
movement is not visible, but with a telescope 
you enlarge the image so much that the mo-
vement becomes clearly visible. To follow the 
celestial objects, you must therefore move 
the telescope along on the mount at regular 
intervals.
