Kendrick Solar Filters

Kendrick Solar Filters

Kendrick Solar filters featuring Baader film 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.

Kendrick Astro Instruments manufactures more models, bar far, than any other solar filter manufacturer. From the largest telescopes, to binoculars and camera lenses, we have a model to fit your application. All models use nylon thumb-screws to secure the filter to your telescope/lens. Nylon is a soft material and will not scratch the pretty paint job. Unlike the other brands' "friction fit" system, our fastening system allows the use of a larger frame which increases the clear aperture area for unobstructed full field of view.

Baader 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.

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. In fact, most experienced solar observers say that "wrinkles" improves image contrast. 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.

Who uses Kendrick Solar Filters?

3 more of our filters just arrived onboard the International Space Station, and this is our 3rd trip into space! The current mission will use Kendrick Solar Filters mounted to conventional telephoto camera lenses. Our filters use Baader Solar Film renowned for its excellent contrast. Of course, thousands of us "terrestrial" dwellers also use Kendrick Solar Filters on our telescopes, binoculars, and camera lenses.

More Info

Filters will attach to the front of your telescope/binoculars/camera lens. There are now thousands of telescopes, binoculars, and camera lenses, so we intentionally avoid stating size information with reference to specific equipment models. But it is really easy to find the right fit. Simply measure the outside diameter of your optical TUBE. NOT the size of the lens or mirror, but rather the diameter of the tube that houses your lens/mirror. If you are using a refractor telescope or camera lens, you have a choice to attach the filter to the Dew-Shield/Lens-Shade OR directly onto the body of the telescope/camera lens. SCT & Dobsonian owners take note....do you have dove-tail bars or other accessories mounted near the front of your telescope? Take those into account when chossing the right fit.

 

Visual Solar Filters with Solar Finder

NEW! Solar Filters with built in sun finder!
The 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.

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.

Solar Finder with Built in Finder Solar Finder Solar Finder Front Solar Finder Back

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.

  • 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.

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)

Visual Solar Filters for Scopes (Classic Ring Style)

STOCK STATUS UPDATE: these models are currently OUT OF STOCK. A possible alternative is to look at our "SF" models with the built-in "Solar Finder"

  • 6001 - Visual Solar Filter (63mm filter aperture), Fits tube ODs 66mm to 76mm - OUT OF STOCK
  • 6001-A : Visual Solar Filter (70mm filter aperture), Fits tube ODs 75mm to 85mm - OUT OF STOCK
  • 6006-A : Visual Solar Filter To Fit 117mm To 123mm OD. - OUT OF STOCK

  • It may be several months before they are back in stock.

    ALL OTHER "Classic Ring" MODELS ARE STILL IN STOCK

    The Classic Ring Style features 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.

    The Classic Ring Style has a more rigid design and replaceable filter rings if the filter gets damaged. The rings are held in place with nylon thumbscrews.

    Please note that these filters cannot accommodate dovetail bars, counterweight bars or other accessories or devices that extend to the front of the telescope. If your telescope has accessories that will interfere with the fit of this particular filter, you must purchase the 6***-SF version of our filters.

    *NOTE: Models 665N and 670N are "OPEN FRAME" filters similar to our "SF" filters except that they do NOT have the built-in "Solar Finder" feature. These same models are sold in pairs for use with binoculars. They are designed for small aperture camera lenses that might not be able to accomodate a wrap-around "collar". Refer to the photo in the Binocular Filter section.

    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 inch measurements to metric, multiply your tube diameter measurement that is in inches by 25.4. This will give you the diameter in millimeters.

    Photographic Solar Filters

    Discontinued (July 2016)
    We sold very few of the Photographic Filters because a Visual Filter CAN be used for photography, but a Photographic Filter CANNOT be used for visual observing.

     

    Visual Solar Filters for Binoculars

    Visual Solar Filters for Binoculars

    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.

    Additional Information

    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 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.
