Never look into the Sun without adequate filtering in frontof your optical instrument. AstroSolar® Film provides thisnecessary safety when mounted into a Baader Solar Filter.Carefully read the instructions to correctly adjust yourBaader Solar Filter in front of your telescope, SpottingScope, Binocular or Camera Lens.

Always attach the safety straps onto the three centeringbolts of the filter and affix the counterparts at the opticaltube to prevent the filter from falling off.

Interrupt solar observation within three minute intervals torelieve your eyes.

If you already know that you suffer from excessive eyesensitivity or eye related diseases, consult yourophthalmologist prior to using this product.

Solar products are not intended for those under 14 years ofage.

Never leave your Solar Telescope outside unattended toprevent children or uninformed visitors from looking at theSun without proper guidance.

Store the filter adequately in a closed box to prevent it fromageing or accidental damage and from collecting dust.

Do not attempt to clean the filter by rubbing it. The filtershould not need cleaning if you store it correctly. You mayonly very lightly brush over it with Optical Wonder cleaningcloth (Baader SKU #2905000).

Do not touch the silver filter film with bare hands (naturalacidic components of the skin may damage the film)

Carefully inspect your filter for damages such asscratches before each observing session. Please also noteour comments on filter quality in Appendix B of this manual.

1. Introduction

After 15 years of offering AstroSolar®film sheets as DIY-product, this systemof Baader Solar Filters is designed toretain the true optical quality of thediffraction limited AstroSolar® SafetyFilm.

Baader Solar Filters provide a professional and securesolution to observe and image the Sun using AstroSolar® SafetyFilm. Many ready made filters do stretch the filter material like adrumhead in order to make it look like a piece of glass - thisabsolutely does destroy the image quality, rendering the filmuseless for high magnification work. AstroSolar® must bemounted entirely stress free in order to perform like a highprecision planeoptical window. It sounds like a contradictionwith traditional perception of quality, but AstroSolar® must showslight ripples! Only when the film is being put under stress by animproper cell mount it performs just like any single side coatedglass-filter made of untreated float glass.

2. Safety Instructions Safety Warning – how to protect your eyes. Please read andfollow the instructions carefully, otherwise your eyes couldsuffer irreversible damage.

Do not use Baader Solar Filters if you do not feel well

informed about the hazards involved in improper use and

handling.

3.1 Preparation

Prepare all parts on a table. Check the Scope of Supply(ASTF: page 5 / ASSF: page 6 / ASBF: page 7) of yourindividual filter to make sure nothing is missing.

3.2 Safety Straps

Prepare the supplied bolts on atable and attach the Safety Strapsto the bolt by pressing the hole inthe strap onto the upper side of thebolt until it rests in the depressedarea in the bolt.

Make sure that the side of thestrap which has the double-stickytape on it faces the table whileapplying it to the bold.

(For ASTF you can choose whichbolt diameter you want to use.Please check clamping rangediagram 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 infront of your objective lens or telescope. It is thereforemandatory to use the three safety straps supplied in thispackage.

Please consider that a strong gust of wind, a loosely fastenedcentering bolt - as well as someone not familiar with the severityof damage that may be caused to the observers eyesight, couldcause even a well fastened solar filter to detach from yourobjective lens or telescope and have the immense amount ofsolar energy fall into the observers eye.

This set of three safety straps provides an easy to use andrepeatable protection to prevent the solar filter from falling offyour 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.

3.3.3 Place combination of the three parts to one of the longholes and make sure that the machined indicator pointsparallel toward the index scale. It should not rotateanymore if the milled surfaces of the slitting fastener arein the correct position according the long holes of thewhite front ring.

(For ASTF you canchoose between the innerand the outer long holes inorder to reach differentclamping areas. Pleasecheck clamping rangediagram at Appendix B)

3.3.5 Hold the combinationgently with one fingerand turn the whole filterring around.

3.3.6 Keep your fingertip onthe head of the M4Phillips screw to avoid itfrom rotating while fastening the bolt.

Only for the ASTF Bolts with 20mm diameter: Each bolt (withthe safety straps already attached) must be mounted with oneadditionally supplied stainless steel washer. Washers are to befitted onto the M4 screw between the centering bolt and thewhite front ring. Make sure that the rounded side of the washersfaces the white front ring.

For other bolts: Fasten the supplied bolts with the safetystraps already attached (see 3.2) at the M4 thread on theopposite side without additional washers in between.

4. Attaching the Filter onto your optics

How to attach your Baader Solar Filter onto your Telescope,Spotting Scope, Binocular or Camera Lens:

4.1 Hold the filter in front of the tube and gently push the threebolts onto the outer rim of your optics. The safety strapsare hanging loosely from the bolts.

4.2 Peel off the carrier film to reveal the sticky bottom of theVelcro tape. Gently stretch out the safety strap (withoutforcing it) and attach the sticky side to your optical tube atmaximum length. Firmly push it to the tube, so that it cannot accidentally come off.

16

In order to firmly lock thecombination, you may use aPhillips head screwdriver togently counter the Phillips headscrew while holding the bolt withtwo fingers.

3.3.7 Only applies to ASTF: Cover the open hole on top withthe 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® Safety Film

Patented AstroSolar® Film is metalized with a coating techniquesimilar to metal coatings applied onto telescope mirrors - but onboth sides of the film! Even a bad rub or removed spot on oneside of AstroSolar® would still only let 50% of the light gothrough the film because the counter side coating stays intact.This proprietary metallization process is noticeably moreresistant than common industrial metallization processes. Theart is - to uniformly metalize the second side withoutdeteriorating the first side at all. Other makers always had touse two layers of film in order to provide two metalized coatinglayers of equal optical density.

Cell mounted AstroSolar® Safety Film does not age nor oxidizeduring storage when protected properly. We have cell mountedAstroSolar® filters in use since 15 years – still providingexcellent image quality because the complete filter assembly isstored safely in a sealed and dry box after each observingsession.

Even the very durable metalized surfaces of AstroSolar®(especially the one facing the sky) may become scratched orage due to accidental touches and by collecting dirt or pollenwhen being left on the telescope uncovered over longer periodsof time. Especially pollen grains do contain a large degree ofethereal oils which work like a weak acid, dissolving the metalcoating over time like they do with multicoatings on lenssurfaces. Pollen grains as well as likewise acidic finger printsmay need to be removed most carefully with the help of mildBaader Optical Wonder Fluid. A certain amount of dust is no

4.3 Now you can lift off the safety strap if you want to removethe filter, but the Velcro counterpart always stays at thetube for quick and easy fastening of the filter onto youroptics.

4.4 Repeat 4.1 to 4.3 for the other two safety straps.

Enjoy observing 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 ontoa white (ASTF) or black (ASSF/ASBF) plastic ring, byusing a special variant of temperature resistant and ageproof double sticky tape. For filter exchange this ringmust be accessed.

5.2.2 Unmount the injection molded black plastic ring from thewhite metal front ring by removing each of the M3Phillips head screws with the help of a smallwatchmakers screwdriver.

5.2.3 The various rings will come apart and provide access tothe ring-side where the filter material is affixed.

5.2.4 Gently lift the film from the holding ring by cutting into themiddle of the filter and pulling the remaining materialfrom inside to outside all around the ring. Doing this withthe right amount of slowness and care will even keep theoriginal sticky tape intact to be right away used foraffixing a new sheet of film.

5.2.5. In case that some of the sticky tape has been lifted offthe plastic ring together with the film removal, then allthe sticky tape needs to be removed and replaced allaround with your own tape solution

5.2.6 Check out the link below and follow the instructions fromparagraph 3 to 7 on how to apply the new film onto theholding ring:astrosolar.com/en/information/how-to/how-to-make-your-own-objective-solar-filter-for-your-camera-or-telescope/

bother and better be left alone rather than be removed byrepeated cleaning processes.

However - heavy wind movement as well as dirt or pollen aswell as their removal procedure itself may lead to the formationof 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 carefullybefore each and every solar session. Someone might haveseverely dented the filter surface during earlier removal from thetelescope or might have severely rubbed the film in an attemptto "clean" it. In each case were the surface quality raisessuspicion during visual inspection by holding it against the Sun -of having large imperfections or scratch marks of more than 0.5mm width, or dented portions with incision marks which mighteven lead to breaking the film - in every such case, the film

must be discharged and replaced.

5.3 Handling and Storage

We suggest you to store the filter in the supplied cardboard boxin a safe and dry place. If you wish to store your Baader SolarFilter fully mounted then we recommend to use a closed plasticcontainer (Tupperware-style) to seal the film completely againstdust and moisture. Thus you can positively protect your filterfrom aging,

You may want to even put some bags of dehumidifyingcompound into the box or use a refurbishable variant which isavailable from Baader Planetarium (Baader SKU #1905160).

24 2525

Baader Solar Filters are available in 3 categories with a total of21 filter sizes:

A.1 ASTF (AstroSolar® Telescope Filter)

This family of solar filters is made in the most elaborate way.AstroSolar® must not be put under stress, neither duringmounting the film, nor during any temperature change. For thisreason the ASTF-Filter features a temperature compensatedcell. The film itself is repeatedly cemented onto an injectionmolded ring, whereas the substrate of that ring has the samethermal expansion coefficient like the AstroSolar® Filter materialitself. This free floating film-carrier ring is held onto thealuminum frame with the help of another holding ring made offiber reinforced plastic - for a maximum of security againstbreaking of the cell. This temperature compensated cell enablesthe AstroSolar® filtermaterial to retain itsexcellent optical quality atany temperature - be it-30°C or +50°C.

ASTF 80 to 280 packagesall come with two sets ofcentering bolts in 38 mmlength (3 bolts with10 mmdiameter and 3 bolts with20mm diameter) to cover awide range of tubediameters.

24

Black sliding washers supplied to securely cover the fulllength of the adjustment slots in the aluminum frame - forblocking sunlight from passing through the filter cell besidethe filter area.

Only for ASTF-filters: Rubber plugs supplied as cover forclosing unused adjustment slots in the aluminum frame.

Three safety straps included, to secure the position of thefilter cell with Velcro-adhesive pads. A safety feature toabsolutely ensure a secure fit in front of the telescopeunder any circumstances (gust of wind asf).

Warning text printed onto the front side of each filter cell:Read the Instructions before use.

Cardboard gift box fit for safely shipping the filter.

Appendix B: Quality information

The following texts and images in B.1 and B.2 depict typicalviews of cell mounted AstroSolar® Film which may appear to beimperfect but which show films that are perfectly withintolerance and which are working without any deterioration to theimage quality.

After mounting and assembly, each Baader Solar Filter haspassed a stringent quality control procedure at our company inMammendorf / Germany.

Boxes are sealed with a clear Baader logo mark. Any seemingimperfections like ripples, dents, or even very small pinholes arewithin the manufacturing tolerance and will not deteriorate theimage quality and most of all will not endanger the userseyesight.

If AstroSolar® Safety Film does collect imperfections over time(note the explanation under B.2) we suggest discharging thefilm. Also check chapter B.1 and B.2 below, or visit our websitewww.astrosolar.com for further information.

The real danger to your filter and eyes (and camera-chip) aresevere scratches or rubbed off zones done to the filter materialinadvertently during handling, were a large amount of themetallization has been scraped off without you noticing it. Alsodents and creases impressed into the film due to accidentaltouching and tearing the filter surface may cause the filter tobreak during observation under heavy wind load. The filtersurface must look "unharmed" in every respect before eachsolar observation session. A filter whose surface looksscratched, dented or otherwise violated must be dischargedand/or the film must be exchanged (see section 5.2).

26

A.2 ASSF (AstroSolar® Spotting Scope Filter)

This family of filters offers a stable and rigid solution for allspotting scopes, tele-lenses and amateur telescopes, withmagnifications up to 120x. The AstroSolar® filter material islikewise mounted onto a plastic ring whereas the plastic ringitself works as stabilizing element for the filter cell. This stillplastic ring is mounted onto the aluminum front frame. Thethermal expansion coefficient of the plastic and the film aresimilar.

ASSF 50 to 100 packages comewith three centering bolts of 13mmdiameter and 24mm length.

ASSF 115 and 130 packages comewith three centering bolts of 10mmdiameter and 38mm length.

A.3 ASBF (AstroSolar® Binocular Filter)

This category is essentially similar to theASSF in terms of mechanics. The onlydifference is that one side is cut off inorder to make them usable on anybinocular - even when the bridge is nearlyclosed. (depending on the binocular type).

ASBF 50 to 100 packages come withthree centering bolts of 13mm diameterand 24 mm height.

recommended to blacken larger pinholes (see instructionsbelow). In the effect that ever more, even tinier pinholes (of just0.1 mm in diameter and smaller) will noticeably brighten theimage then it might be a good time to exchange the film in thecell with the help of the same procedures as described in greatdetail on www.astrosolar.com for DIY-production of filter cells.

Tiny pinpoint sized bright spots can be blackened on the insideof the Solar Filter (the side facing the telescope) by applying atiny black spot, using a black felt marker or soot filled blackpaint. Apply with small retouching brush. Considering the totaloptical surface area, such small black spots do not have anyadverse effect on optical quality. Rather you will notice anincrease in contrast within finest solar surface details.

28

B.1 Folds, Ripples, Creases

Any of the film patterns shown below are remains of the entirelystress free production processes that AstroSolar® has toundergo. Trying to avoid such surface textures inevitably leadsto gross astigmatism and noticeable loss of image sharpness.In fact these patterns do not influence the quality of the imageat all. Do not let yourself be mislead by looking for thecosmetics instead of the optical outcome.

B.2 Pinholes

Before each use carefully inspect your filter by holding it againstthe Sun. Pinholes smaller than 0.5 mm in size do not constitutea safety problem since 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 overlapto brighten the background of the real solar image created bythe telescope optics.

Over time many such pinholes would noticeably deteriorate thecontrast visible in the solar surface details. For this reason it is
