    Even after the sun eclipse sun observations are of great enjoyment. The sunspots are constantly changing their size, shape and position. Depending on the magnification used even the Umbra and Penumbra, center and edges of the sunspots are visible. It is, however, of essential importance for the protection of your eyes to reduce the sunlight to less than 1/100,000 of its normal brightness. The Astro Solar Sun Filter Foil provides these conditions. It needs simply to be mounted on the front opening of the telescope tube. The Astro Solar Sun Filter Foil meets highest quality requirements and is therefore comparable to expensive plan parallel glass filters. The foil production is under permanent and strict quality control. The multi-reflective foil guarantees an extraordinary even filter effect, so that just one layer of the foil will be sufficient for sun observations.
