A COSMETIC NOTE ABOUT BAADER SOLAR FILM

Unlike glass filters, Baader film does not have a perfect cosmetic surface. Wrinkles, folds, kinks, pinholes and other imperfections in this film are normal and will be present on any Baader film solar filter purchased from us. These do not affect the image quality or safety of the filter. Pinholes, even at full solar intensity, work as a camera obscura. This means that each pinhole would project its own solar image, just like eyepiece projection.

Anyone expecting or requiring a perfect cosmetic filter surface should consider another manufacturer's filter.

Having said this, know that Baader film filters are famous for their exquisite sharpness and detail across the entire field of view in an eyepiece and have a very pleasing and comfortable image brightness.

Also, this film is incredibly tough and does not break or tear easily. To puncture it with a blunt object takes a lot of force, much more force that would be used in normal day to day useage. And if by unfortunate chance the filter does get damaged, the film in the filter can be replaced. We will be offering internal replacement filter rings very soon.

HOW TO CHOOSE THE CORRECT SIZE FILTER

The most important piece of information you will need to choose a filter is the diameter (not circumference) of your telescope tube or dewcap (whatever the filter will fit over) or the diameter of your camera lens or the diameter of the barrels on your binocular. Ultimately, this is more important than the aperture diameter shown in our shopping cart.

When you know the diameter of the device that the filter is meant to fit over, choose the appropriate filter in the shopping cart below based on the spec that says, for example, "(Fits 245mm to 275mm tube)". DO NOT USE the filter aperture spec in our shopping cart or your lens optical diameter as a guide to purchase your filter.

CAN I USE A PHOTOGRAPHIC FILTER FOR VISUAL USE?

CAN I USE A PHOTOGRAPHIC FILTER TO VIEW THE SUN?

The same question is often asked in reverse, "Can I use a visual filter for photography?".
A photographic filter cannot be used visually as the image is just too bright to be observed safely.
A visual filter can be used photograpically but you lose an F stop and will have to use longer exposure times which can degrade solar details due to atmospheric turbelence.

SUN FINDER




SUN FINDER: For use with filters and telescopes with out a built in solar finder Makes locating the sun and centering it in your eyepiece a cinch! The finder projects a solar dot onto the white target which can be viewed either from the from the front of the finder or through the cut out on the back. The finder comes with a double sided adhesive foam tape to easy adhesion to a solar filter ring or other surface. Feedback from our field testers is that everyone loved it! This is the same finder that is built into 6000-SF line of solar filters.

SOLAR FILTERS for BINOCULARS

NOTE: To ensure proper fit of the solar filter you must measure the outside diameter of the of the binocular barrel (not the lens diameter). To convert inch measurements to metric, multiply your diameter measurement that is in inches by 25.4. This will give you the diameter in millimeters.

Note that any of our filters can be used for binoculars so if the sizes below are not big enough, check the list of our single filters for the proper size and buy two.

Visual Solar Filters for Binoculars

VISUAL SOLAR FILTERS

We offer two styles of Visual solar filters. One style has a built in Solar Finder and the second is our Classic ring style. Both have their advantages so choosing which style you use is a personal matter. To help you decide, we have laid out the benefits of each style below:

With Built in SOLAR FINDER
Avoids dovetails, counterweights bars and otherdevices or objects that would prevent a standard ring stylefilter from fitting properly.
Has built in Solar FInder to help locate and center the sun in your eyepiece. (Actually much harder to do that many would initially assume.
Lighter weight design. Will not unbalance your telescope.
Very easy to replace the filter ring if the solar filter material gets damaged.
Held in place with nylon thumbscrews.

CLASSIC Ring style
Solid metal collar all the way around the outside of the filter ring. Some of our customers prefer this style as they feel more secure about this type of design. But, if your telescope has objects that extend to the front or the telescope barrel and will not accept a ring design, you will have to consider a filter with the built in solar finder.
More rigid design.
Replacable filter rings if filter gets damaged.
Held in place with nylon thumbscrews.

BAADER FILTERS with Built in Solar Finder

NEW! Solar Filters with built in sun finder!
Our new design has a built in sun finder making centering the sun in your eyepiece very easy. The finder target is visible from both the front and back sides of the filter making centering the sun easy from either end of the telescope.

As well, we have replaced the filter rims with three tabs that contain a secure threaded insert and a nylon thumb screw, making the filter much lighter without reducing the security of the fit. The main reason we made this particular change is that many telescopes have dovetails or other attachments that interfere with the proper fitting of a solar filter to the telescope. Now the filter can be placed onto the scope so that the three thumb screws always firmly attach to the body of the scope. As well, the tabs extend down far enough to allow the thumbscrews to connect beyond the bevels found on some dewcaps or the corrector plate rings and tube rings of some telescopes, ensuring a very secure connection to the telescope.

The filter material itself is the famous BAADER AstroSolar Film. This film has set a new standard for white light filters and gives a very pleasing and high resolution image. The image color is a bluish white. The filters are available in photographic film also.
Constructed of aluminum.

VISUAL FILTERS (ND 5.0)
NOTE: To ensure proper fit of the solar filter you must measure the outside diameter of the front opening of the telescope, binoculars or lens. To convert measurements in inches to metric, multiply your measurement that is in inches by 25.4. For example, a dewcap that is 6.25" outside diameter will be 159 mm (6.25 x 25.4 = 158.75mm)

BAADER FILTERS (Classic Ring Style)

NOTE: These filters cannot accomodate dovetail bars, counterweight bars or other accessories or devices that extend to the front of the telescope. If your telescope has accessories that will interfer with the fit of this particular filter, you must purchase the 6***-SF version of our filters.

R-60 ALUMINUM RINGS

Kendrick is now offering a line of finished R-60 Aluminum Rings to our customers who wish to make their own solar filters or create their own Kwik Focus for sharp focus when astro imaging or for visual observing.
R-60 Aluminum Rings include:

1 x Powder coated aluminum ring
3 x Nylon thumb screws
3 x Felt tabs
1 x Instruction sheet

All our R-60 rings are powder coated off-white and come with three nylon thumb screws to allow for secure attachment to your telescope. Our rings are built in 10mm increments, from 66mm to 405mm. We also have a ring to fit 435mm to 445mm. To determine which ring you will need, measure the outside diameter of your telescope tube in millimeters (or convert inches to decimal, X" x 25.4 = millimeters) and order the ring that most closely matches your dimensions. If your telescope tube diameter is identical to the widest measurement of the ring, we recommend you go up to the next size. The thumb screws will take up any slack that may exist.

Instructions:

Make your own Kwik Focus (PDF Format)

CARE & CLEANING

It is important to note that pollen granules contain aetheric oil and aetheric oil will dissove optical coatings on any optic, even very expensive optics (not just Baader Astro Solar Film). If your filter accumulates pollen, it should be carefully cleaned off at your earliest opportunity with a very soft brush or blown off with a hand operated air bulb.
The good thing about Baader film is that it is coated on both sides, so pollen accumulation will only affect one side of the filter. Consequently there is no danger to your eyes even if pollen accumalation does damage the coating.

Privacy Statement: All information submitted to Kendrick Astro Instruments will be treated with the utmost confidentiality and privacy. We do not share any information with any outside parties whatsoever.
