K20mm eyepiece (e) which provides the lowest power but the brightest image. Replace the K20mm
with the supplied K10mm to get more magnification if necessary. You may need to re-focus when
changing eyepieces.
3.2. Sun observations. A telescope should never be pointed to the Sun or its vicinity. The Sun light
entering the telescope will concentrate in the eyepiece. It will cause permanent retina damage or
even blindness to the observer. For Sun observation, a dedicated front aperture filter is required
(supplied).
Before observing the Sun check the supplied Sun filter. The Sun filter is
made from a special coated plastic foil that is fragile and can easily be
scratched or pierced. Examine the solar filter with a strong incandescent
bubble light (placing the filter between the light bulb and you). Make
sure that no holes or scratches are visible. You should however see the filament of the light. Filter
with no holes or scratches are usual in good condition for Sun observation. 3.2.1. Fitting the solar
filter to the telescope. Now that the filter (3.2.) fit it to the telescope as shown. The filter should
have a tight fit to the telescope and should not fall-off during the Sun observation – figure 15 & 16.
