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 BDSF Filters (OD 3.8) for visual observation.
Always attach the safety straps onto the three centering
bolts of the filter an
d 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 ophthalmologist 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 vi
sitors from looking at the
Sun without proper guidance.
Store the filter adequately in a closed box to prevent it from
ageing or acci dent al 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 d
amage 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 Fi lm. Many ready-made filters do
stretch the filter material like a drumh
ead i n 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 p recisi on 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 s
ingle side coated glass-filter made of untreated
float glass.
2. Safety Instructions
Safety Warning – how to protect your eyes. Please read a nd
follow the instructions carefully, otherwise your eyes could
suffer irreversible damage.
Do not use Baader Solar Filters if you do not feel well
informed about the hazards involved in improper use and
handling.
8 9
3.1 Preparation
Prepare all parts on a table. Check the Scope of Supply
(ASTF and BDSF: page 5 / ASSF: page 6 / ASBF: page 7) of
your individual filter to make sure nothing is missing.
3.2 Safety Straps
Prepare the supplied bolts on a
table and attach the Safety
Straps
to
the bolt by pressing the hole i n
the strap onto the upper side of
the
bolt until i t rests in the depressed
area in the bolt.
Make sure that the si de of the
strap which has the double-stic
ky
tape on it faces the table while
applying it to the bold.
(For ASTF / BDSF
you can choose
which bolt diameter you want to
use. Please check clamping range
diagram at Appendix B)
3. Assembly
Instructions
Solar Safety First! – prevent
your solar filter from falling off
your telescope. For your own
safety – attach safety straps
Utmost care is necessary when positioning your solar filter in
front of your objective lens or telescope. It is therefore mandatory
to use the three safety straps supplied in this package.
Please consider that a strong gust of wind, a loosely fastened
centering bolt - as well as someone not fami
liar with the severity
of damage that may be caused to the observers eyesight, could
cause even a well fastened solar filter to detach from your
objective lens or telescope and have the immense amount of
solar energy fall into the observers eye.
This set of three safety straps provides an easy to use and
repeatable protection to prevent the solar filter from falling off
your solar observation device under any circumstances.
Please read the instructions on how to mount
the safety
straps thoroughly and carefully. Do not miss to make use
of this important safety feature.
Important note:
The eye safety norm EN ISO 12312
-
2:2015
for naked eye solar viewers does
not apply to front aperture filters, covering long-range optics. AstroSolar®Safety Film 5.0 is not
authorized to be used for naked eye solar observation or production of solar viewers. For direct
solar viewing without telescope, binocular or camera optics, inquire for our EN ISO 12312-
2:2015 certified eclipse shades equipped with AstroSolar®Silver/Gold Film.

4. Attaching the Filter onto your optics
How to attach your Baader Sol ar Filter onto your Telescope,
Spotting Scope, Binocular or Camera Lens:
4.1 Hold the filter in front of the tube and gently push the three
bolts onto the outer rim of your optics. The safety straps
are hanging loosely from the bolts.
4.2 Peel off the carrier film to reveal the sticky bottom of the
Velcro tape. Gently stretch out the safety strap (without
forcing it) a nd attach the sticky side
to your optical tube at
maximum length. Firmly push it to the tube, so that it can
not accidentally co me off.
In order to firmly lock the
combination, you may use a
Phillips head screwdriver to
gently counter the Phillips head
screw while holding the bolt with
two fi ngers.
3.3.7 Only applies to ASTF / BDSF: Cover the open hole on
top with th e supplied rubber plug.
Repeat 3.2 to 3.3.7 for the two other bolts.
Your Baader Solar Filter is now ready for use.

5. Maintenance
5.1 Durability of AstroSolar® Film
Patented AstroSolar®Film is metalized with a coating technique
similar to metal coatings applied onto telescope mirrors - but on
both sides of the film! Even a bad rub or removed spo t on one
side of AstroSolar
®
would still only let 50% of the light go
through the film because the counter side coating stays intact.
This proprietary metallization process is noticeably more
resistant than common industrial metalli
zation processes. The
art is to uniformly metalize the second side without deteriorating
the first side at all. Other makers always had to use two layers
of film in order to provide two metalized coating layers of equal
optical density.
Cell mounted AstroSolar
®
Film does not age nor oxidize during
storage when protected properly. We have cell mounted
AstroSolar
®
filters in use since 25 years – still providing
excellent image quality because the c omplete filter assembly is
stored safely in a sealed and dry box after each observing
session.
Even the very durable metalized surfaces of AstroSolar
®
(especially the one facing the sky) may become scratched or
age due to accidental touches and by collecting dirt or pollen
when being left on the telescope uncovered over longer periods
of time. Especially pollen grains do contain a large degree of
ethereal oils which work like a weak acid, dissolving the metal
coating over time like they do with multico
atings on lens
surfaces. Pollen grains as well as likewise acidic finger prints
may need to be removed most carefully with the help of mild
Baader Optical Wonder Fluid. A certain amount of dust is no
4.3 Now you can lift off the safety s trap if you want to remove
the filter, but the Velcro counterpart always st ays at the
tube for quick and easy fastening of the filter onto your
optics.
4.4 Repeat 4.1 to 4.3 for the other two safety straps.
Enjoy observing or imaging the sun
with your Baader Solar Filter!

5.2 Exchanging AstroSolar® Film
5.2.1 Each sheet of film is being cemented in our factory onto
a white (ASTF / BDSF) or black (ASSF/ASBF) plastic
ring, by using a special variant of temperature resistant
and age proof double sticky tap e. For filter exchange this
ring must be accessed.
5.2.2 Unmount the injection molded black plastic ring from the
white metal front ring by removing each of the M3
Phillips head screws with the help of a small
watchmakers screwdriver.
5.
2.3 The various rings will come apart and provide access to
the ring-side where the filter material is affixed.
5.2.4 Gently lift the film from the holding ring by cutting into the
middle of t he filter and pulling the remaining material
from inside to outside all around the ring. Doing this with
the right amount of slowness and care will even keep the
original sticky tape intact to be right away used for
affixing a new sheet of film.
5.2.5. I n case that some of the sticky tape h
as been lifted off
the plastic ring together with the film removal, then all
the sticky tape needs to be re moved and replaced all
around with your own tape solution
5.2.6 Ch eck out the link below and follow the inst ructions from
paragraph 3 to 7 on how to apply t he new film onto the
holding ring:
www.astrosolar.com/en/information/how-to/how-to-make-yourown-objective-solar-filter-for-your-camera-or-telescope/
bother and better be left alone rather than be removed by
repeated cleaning processes.
However - heavy wind movement as well as dirt or pollen as
well as their removal procedure itself may lead to the formation
of small pinholes in the metallization. Please see Appendix A
(A.2) for further information on Pinholes.
Still the cell mounted filter MUST be inspected most carefully
before each and every solar session. Someone might have
severely dented th e filter surface during e
arlier removal from the
telescope or might have severely rubbed the film in an attempt
to "clean" it. In each case were the surface quality raises
suspicion during visual inspection by holding it aga inst the Sun of having large imperfections or scratch marks of more than 0.5
mm width, or dented portions with incision marks which might
even lead to breaking the film - in every such case, the film
must be discharged and replaced.

5.3 Handling and Storage
We suggest storing the filter in the supplied cardboard box in a
safe and dry place. If you wish to store your Baader Solar Filter
fully mounted we recommend use of a closed plastic container (Tupperware-style) to seal the film completely against
dust and mo isture. Thus you can positively protect your filter
from aging.
You may want to even put some bags of dehumidifying
compound into the box or use a refurbishable varia
nt which is
available from Baader Planetarium (Baader SKU #1905160).

*BDSF: FOTO Film
Baader Solar Filters are available in 3 categories with a total of
21 filter sizes:
A.1 ASTF / BDSF (AstroSolar®Telescope Filter)
This family of solar filters is made in the most elaborate way.
AstroSolar
®
must not be put under st ress, neither during
mounting the film, nor during any temperature change. For this
reason the ASTF-Filter features a temperature compensated
cell. The film itself is repeatedly cemented onto an injection
molded ring, whereas the substra
te of that ring has the same
thermal expansion coefficient like the AstroSolar
®
Filter material
itself. This free floating film-carrier ring is held onto the
aluminum frame with the help of another holding ring made of
fiber reinforced plastic - for a maximum of security against
breaking of the cell. This temperature compensated cell enables
the AstroSolar
®
filter
material to retain its
excellent optical quality at
any temperature - be it
-30°C or +50°C.
ASTF 80 to 280 p
ackages
all come with two sets of
centering bolts in 38 mm
length (3 bolts with10 mm
diameter and 3 bolts with
20mm diameter) to cover a
wide range of tube
diameters.
Most ASTF filter sizes are additionally available in the version
“BDSF“ (Baader Digital Solar Filter) with AstroSolar
®
Photo Film
3.8.
Ind ex s cale provided beside each adjustment slo t -
adjacent to each sliding fastener, for fast and repeatable
adjustment of t he filter cell onto different telescope tubes.
Black sliding washers supplied to securely cover the full
length of the adjustment slots in the aluminum frame - for
blocking sunlight from passing th rough the filter cell beside
the filter area.
Only for ASTF/BDSF Filters:
Rubber plugs supplied as
cover for closing unused adjustment slots in the aluminum
frame.
Three safety straps included, to secure the position of the
filter cell with Velcro-adhesive pads. A safety feature to
absolutely ensure a secure fit in front of the telescope
under any circumstances (gust of wind asf).

Appendix B: Quality information
The following texts and images in B.1 and B.2 depict typical
views of cell mounted AstroSolar
®
Film which may appear to be
imperfect but which show films that are perfectly within
tolerance and which are working without any deterioration to the
image quality.
After mounting and assembly, each Baader Solar Filter has
passed a stringent quality control procedure at our company in
Mammendorf / Germany.
Boxes are sealed with a clear Baader
logo mark. Any seeming
imperfections like ripples, dents, or even very small pinholes are
within the manufacturing tolerance and will not deteriorate the
image quality and most of all will not endanger the users
eyesight.
If AstroSolar
®
Film does collect imperfections over time (note
the explanation under B.2) we suggest discharging the
Film. Also check chapter B.1 and B.2 below, or visit our website
www.astrosolar.com
for further information.
The real dang er to your filter and eyes (and camera-chip) are
severe scratches or rubbed off zones done to the filter material
inadvertently during handling, were a large amount of the
metallization has been scraped off without you noticing it. Also
dents and creases impressed into the film due to accidental
touching and tearing the filter surface may cause the filter to
break during observation under heavy wind load. The filter
surface must look "
unharmed" in every respect before each
solar observation session. A filter whose surface looks
scratched, dented or otherwise violated must be discharged
and/or the film must be exchanged (see section 5.2).
A.2 ASSF (AstroSolar®Spotting Scope Filter)
This family of filters offers a stable and rigid solution for all
spotting scopes, t ele-lenses and amateur telescopes, with
magnifications up to 120x. The AstroSolar
®
filter material is
likewise mounted onto a plastic ring whereas the plastic ring
itself works as stabilizing element for the filter cell. This still
plastic ring is mounted onto the aluminum front frame. The
thermal expansion coefficient of the plastic and t
he film are
similar.
ASSF 50 to 115 packages come
with three centering bolts of 13mm
diameter and 24mm length.
ASSF 130 and 150 packages come
with three centering bolts of 10mm
diameter and 38mm length.
A.3 ASBF (AstroSolar®Binocular Filter)
This category is essentially similar to the
ASSF in terms of mechanics. The only
difference is that one side is cut off in
order to make them usable on any
binocular - even when the bridge is nearly
closed. (depending on the binoc
ular type).
ASBF 50 to 100 packages come with
three centering bolts of 13mm diameter
and 24 mm height.
26 27
Pinholes smaller than 0.5 mm in size do not constitute a safety
problem sin ce each such pinhole works as a minute "camera
obscura" - producing a real image of the solar disk - although of
extremely low resolution - given the ever so tiny "aperture".
Several such "solar ghost images" then do overlap to brighten
the background of the real solar imag e created by the telescope
optics.
Over time many such pinholes would noticeably deteriorate the
contrast vis ible in the solar surfa
ce details. For this reason it is
recommended to blacken larger pinholes (see instructions
below). In the effect that ever more, even tinier pinholes (of just
0.1 mm in diameter and smaller) will noticeably brighten the
image then it might be a good time to exchange the film in the
cell with the help of the same procedures as described in great
detail on www.astros olar.com
for DIY-production of filter cells.
Tiny pinpoint sized bright spots can be blackened on the inside
of the So lar Filter (the side facing the telescope) by applying a
tiny black spot, using a black felt marker or soot filled black
paint. Apply with small retouching brush. Considering the total
optical surface area, such small black spots do not have any
adverse effect on optical qualit y. Rather you will notice an
increase in c ontra st within finest solar surface details.
B.1 Folds, Ripples, Creases
Any of the film patterns shown below are remains of the entirely
stress free production processes that AstroSolar®has to
undergo. Trying to avoid such surface textures inevitably leads
to gross as tigmatism and noticeable lo ss of image sharpness.
In fact these patterns do not influence the quality of the image
at all. Do not let yourself be mislead by looking for the
cosmetics instead of the optical outcome.
B.2 Pinholes
Before each use carefully inspect your filter for mechanical
damages, broad scratches, streaks, extensive wipe marks and
other quality de grading influences:
ASTF / ASSF / ASBF (AstroSolar® Safety Film 5.0):
by holding it very briefly at arms length towards the Sun.
BDSF (AstroSolar
®
Photo Film 3.8):
By holding it at arms length towards a bright LED or Halogen
lamp
