2.4 Tracking a celestial object
You can easily follow a celestial object by moving the telescope in its two axes. In astronomy one speaks of
‘guiding’ the telescope.
1. You must first accurately position the celestial object in the eyepiece, as described above.
2. Due to celestial objects appearing to move in the eyepiece due to the earth’s rotation, you must constantly
adjust the telescope in order to keep them in view. The azimuth axis remains unlocked during guiding.
Gently pushing the telescope tube allows you to change its position.
3. As objects describe an arc in the sky, you must always move both axes in order to keep objects centred.
You will also need to use the elevation fine adjustment control on the elevation rod to stop objects
‘wandering’ out of the field of view.
Movements in both axes must be made as sensitively as possible. With a little practice you will soon get the
knack.
