11. Dismantling the Telescope
Hopefully your observation session will have
been interesting and successful; afterwards,
it is recommended to store the telescope in
a dry and well-ventilated room. Please do not
forget to place the lens caps back onto the
front tube opening and the eyepiece holder.
All eyepieces and optical accessories should
also be stored in their respective containers.
TIP:
The inverting lens is not suitable for astrono-
mical observation. Here, work with just the
zenith mirror and an eyepiece. For terrestrial
observations and for viewing nature, you may
use the inverting lens with an eyepiece.
Problem Solution
No image Remove lens cap from lens opening
Fuzzy image Adjust focus with focus adjustment knob
Focusing is not possible
Wait for temperatures inside tube to balance
out (about 30 minutes)
Bad image Never observe through a pane of glass.
Object of observation is visible in finder,
but not in telescope
Align finder (see chapter 7)
Sluggish or stiff steering of the shafts Balance telescope
Image is “askew,” even with zenith mirror
The eyepiece holder in the zenith mirror
must be aligned vertically
