Kendrick Baader 4" (113mm - 143mm) Solar Filter (6007-SF)
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.
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 colour 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.
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 note....do 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 dewcap that is 6.25" outside diameter will be 159 mm (6.25 x 25.4 = 158.75mm)
- Visual Solar Filter with Solar Finder, (110 filter aperture) Fits tube ODs 113mm to 143mm
- 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.
