3.5 When you have finished observing, turn the telescope tube away from the Sun before removing
the filter from the lens.
4. Overview of safety instructions
4.1 Never look at the Sun with a telescope, binoculars or similar without a solar filter attached to the lens.
Observing without a solar filter leads to immediate blindness.
4.2 Always attach the solar filter to the lens of your optics and make sure that it cannot be blown away by a
gust of wind.
4.3 Never look through a finderscope without a solar filter attached to the finderscope lens. An unprotected
glance through a finderscope leads to the immediate destruction of the retina. In addition, the concentrated
light can cause severe burns if it reaches the skin. For safety, remove the finderscope from the telescope tube.
4.4 Check the solar filter for damage before every observation.
4.5 To avoid damage, keep the solar filter away from light and away from sharp objects.
4.6 This filter is not intended for use on an eyepiece.
4.7 For visual observation, only use solar filters with optical density ND of 5. Filters with lower optical density
should not be used for visual observation.
4.8 If your eyes are very light sensitive, or if you have eye disease, check with your doctor before observing the
Sun.
4.9 Never allow children to observe alone: observing the Sun should always be carried out in the presence of a
trained adult.
4.10 After observing the Sun for a few minutes, take a short break before looking through the eyepiece again.
Safety notice
Only a correctly attached and faultlessly-functioning solar
filter can ensure that your observation of the Sun is safe.
