Never look into the Sun without adequate filtering in front
of your optical instrument. AstroSolar
®
Safety Film 5.0
provides this necessary safety when mounted into a
Baader Solar Filter. Carefully read the instructions to
correctly adjust your Baader Solar Filter in front of
your telescope, Spotting Scope, Binocular or Camera Lens.
Never use B
D
SF Filters (OD 3.8) for visual observation.
Always attach the safety straps onto the three centering
bolts of the filter and affix the counterparts at the optical
tube to prevent the filter from falling off.
Interrupt solar observation within three minute intervals to
relieve your eyes.
If you already know that you suffer from excessive eye
sensitivity or eye related diseases, consult your ophthalmo-
logist prior to using this product.
Solar products are not intended for those under 14 years of age.
Never leave your Solar Telescope outside unattended to
prevent children or uninformed visitors from looking at the
Sun without proper guidance.
Store the filter adequately in a closed box to prevent it from
ageing or accidental damage and from collecting dust.
Do not attempt to clean the filter by rubbing it. The filter
should not need cleaning if you store it correctly. You may
only very lightly brush over it with Optical Wonder cleaning
cloth (Baader SKU #2905000).
Do not touch the silver filter film with bare hands (natural
acidic components of the skin may damage the film)
Carefully inspect your filter for damages such as
scratches before each observing session. Please also note
our comments on filter quality in Appendix B of this manual.

1. Introduction
After 25 years of offering AstroSolar
®
film sheets as DIY-product, this system
of
Baader Solar Filters
is designed to
retain the true optical quality of the
diffraction limited AstroSolar
®
Safety
Film 5.0 / AstroSolar
®
Photo Film 3.8.
Baader Solar Filters
provide a professional and secure
solution to observe (OD 5.0) and image (OD 5.0 or 3.8) the Sun
using AstroSolar
®
Safety Film. Many ready-made filters do
stretch the filter material like a drumhead in order to make it
look like a piece of glass - this absolutely does destroy the
image quality, rendering the film useless for high magnification
work. AstroSolar
®
must be mounted entirely stress free in order
to perform like a high precision planeoptical window. It sounds
like a contradiction with traditional perception of quality, but
AstroSolar
®
must show slight ripples! Only when the film is
being put under stress by an improper cell mount it performs
just like any single side coated glass-filter made of untreated
float glass.
