THREADED CAMERA SOLAR FILTER
An absorptive filtering material is spread through the substrate and the optical filter should be handled with extreme care to avoid damaging the thin film. The filter can be cleaned as frequently as needed with a clean soft cloth and isopropyl alcohol. When the filter is not in use, it should be placed in its protective case to minimize any possible accidental damage. Once the thin film has been punctured, the filter cannot be used.
Your camera and the solar filter should be placed in the shade outside and let it sit for fifteen minutes before observing through it. This allows for the camera and filter to become adapted to the temperature. There are fine threads on the solar filter that will fit the threads of your lens. Screw the filter on carefully until snug, being careful not to cross thread the lens or strip the threads.
-Before using the filter, check for any damage.
-Let the camera and filter sit for fifteen minutes minimum in the shade so they can adapt to the temperature.
-Direct sunlight can cause damage to the camera and lens causing poor quality of the image.
-Stand over grass areas for viewing to minimize surface heat currents.
-Do not remove solar filter with camera pointed toward the sun.
The neutral density of this threaded filter is rated at a 5. This reduces the light approximately 100,000 times. It is recommended that you set your camera in program mode at the start and then manually adjust if desired. Longer exposure is necessary when a higher magnification is used.
