Seymour Solar ND5 filter film 229 x 305 mm
You can use this sheet to make a filter for safe solar observing, which is attached to the front of the lens of your telescope, camera, or other optics. The strong cardboard box to build a suitable stand is not included in the scope of delivery, only the special film.
The film has a neutral density of 5, which means it blocks 99.999% of incoming light, including harmful UV rays. Observing the sun is only safe with a filter with this high filter effect! Before using the filter, always make sure there are no tears or wrinkles. With careful and dust-free storage, the film is very durable in this regard.
The film is only 0.05 millimeters thick. It is very easy to trim with scissors or a craft knife.
The image of the sun appears through this sheet in a natural orange-yellow. You can use it to observe sunspots, granulation, and the transit of Mercury in the photosphere.
