“Within Reach” – Observing Our Central Star


The sun is our central star, from which we live. That alone should be reason enough to observe it even more closely. The new Astromania solar filters let you do that easily and above all safely, and are specially tailored to your telescope.

Main Features

Easy to Use

Do you want a solar filter which does not involve any DIY? One which you can simply push onto the end of your telescope and immediately start solar observing? Then an Astromania solar filter is the perfect choice – they come fully assembled in an anodized aluminium mount. Which means you simply attach it and our Sun immediately becomes “within reach”.

Superior Quality

Our complete line of Safety Film Solar Filters feature renowned Baader AstroSolar Safety Film in a sturdy, clear-anodized aluminum cell. The high-quality polymer film material is metallized on both sides with an ion-deposited coating to form a safe barrier against all but 0.0001% of incoming sunlight, providing a clear, crisp view while rejecting harmful ultraviolet and infrared radiation.

With exceptional resolution and superior contrast compared to Mylar and other solar filter materials, Astromania Solar Filters display a natural, neutral white view of the Sun’s surface, without artificial tinting. Once attached to a telescope, these filters provide sharp, scatter-free views of sunspots, solar eclipses, planetary transits, solar granulation, and even white filamentary faculae – the latter of which cannot be seen with most other solar filters.

Versatile Usage

Due to their neutral color balance, Astromania Safety Film Solar Filters can be used in tandem with various color eyepiece filters to accentuate certain spectral passbands for telescopic studies of different layers within the solar “atmosphere”.

Frequently Asked Questions

1. Can I use my telescope if the sun filter is damaged?

No, it is important to never use your telescope if the sun filter is in any disrepair. Using a damaged filter can result in permanent eye damage.

2. Why do some solar filters have wavy lines on the film?

Some solar filters may have wavy lines on the film due to their larger diameter. However, these lines will not have any effect on observation.
