Product Description

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 dew caps or the corrector plate rings and tube rings of some telescopes, ensuring a very secure connection to the telescope.

Baader AstroSolar Film

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.

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. 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 usage.

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.

Attachment Details

Filters will attach to the front of your telescope/binoculars/camera lens and clamp onto the outside of the optical tube assembly (OTA). There are now thousands of telescopes, binoculars, and camera lenses and we can't keep track, 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 you have dove-tail bars or other accessories mounted near the front of your telescope? Take those into account when choosing the right fit.

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 dew cap that is 6.25" outside diameter will be 159 mm (6.25 x 25.4 = 158.75mm)

Kendrick Filter

Only two fairly minor gripes for not giving 5 stars:
- it would be nice if the filter came with a carry case of some kind, the packing box can be used but is probably not going to survive a lot of field use
- the solar finder sight gets you "in the ballpark" with a longer FL scope (925 EdgeHD) while using a low power EP, but there's still a bit of fussing around with the handcontroller and looking thru the EP to get the sun into the field of view

Well made, easy to use

Made for great observation during the recent eclipse. Very easy to aim.


Nicolas was very helpful. Good place to buy your telescope!

Works as specified

The filter works great! I attached it to my lens and rushed outside to snap a photo of the midday sun. The aiming aid is a definite must-have! I can hardly wait for the partial eclipse (Oct 14) and the total eclipse (Apr 8).

I have not tested the filter, beyond holding it up toward the sun. It appears to block all light except the sun. I plan to use it with our telescope soon.
