Product Description

The Astromania solar filter comes already assembled in a plastic frame. That means that you will not have to tinker around or construct anything. This filter makes it simplicity itself for you to use - just attach it to your telescope and it already fits perfectly. This solar filter is made using a special filter foil that provides you with a neutral white image of the Sun. With a filter factor of 100,000 times, only 0.001% of the sunlight entering the telescope reaches your eye, which means you can always observe the Sun in perfect safety. This filter is fantastic for when you want to observe sunspots and solar flares and also for observing granulation on the surface of the Sun. It is also great for observing solar eclipses - it is breath-taking watching the Moon gradually obscure the Sun’s disc.The Sun always shows some exciting detail. Keep a record of the spots and flares with your camera and become a solar photographer. You can also keep track of how an entire sunspot group evolves. Nothing could be easier! Included in delivery is an adhesive foam ring, with which the filter can be reduced to the correct diameter.
